After years of criticism, Amazon appears to be cutting down on plastics

After years of criticism for its outsize use of plastic, the world’s largest retailer appears to be making progress to reduce its plastic footprint.

Amazon announced in its latest sustainability report on Tuesday that orders shipped from its fulfillment centers used 85,916 metric tons of single-use plastic in 2022 — an 11.6 percent decrease from the amount used in 2021.

The company attributed this decline to its expanded use of paper-based packaging, as well as an increased effort to ship items in their original containers — without adding any Amazon-branded packaging. Amazon has also stopped using nonrecyclable bags made of mixed materials, and on Tuesday it said it was “phasing out” padded plastic mailers — those ubiquitous blue and white envelopes studded with the Amazon logo — in favor of “recyclable alternatives.”

Eliminating padded plastic mailers is a “big, big deal,” said Matt Littlejohn, senior vice president for strategic initiatives for the nonprofit Oceana, although he called on the company to set a concrete timeline for doing so. He called Amazon’s sustainability report “good news for the oceans,” since plastic film like the kind used in Amazon’s packaging is one of the most common forms of marine plastic litter and is the deadliest type of plastic to marine animals

Plastics have other impacts, too: They’re made of fossil fuels and are a major source of climate pollution, and they cause toxic chemical pollution at every stage of their life cycle. Meanwhile, the U.S. recycling rate for plastics is just 5 percent, meaning the vast majority of plastics are littered, burned, or sent to a landfill.

Amazon’s 2022 sustainability report is the first to include a quantitative estimate of the company’s single-use plastics footprint; previously, the company’s only other estimate came from a blog post last December. Before that, organizations like Oceana had to publish their own estimates and had called for greater transparency — sometimes through investor pressure. Over the past three years, shareholder advocacy groups have repeatedly filed resolutions demanding that Amazon disclose the amount of plastic it uses and reduce it by one-third by 2030. One resolution, co-filed in December 2021 by Green Century Capital Management and As You Sow, was supported by nearly half of Amazon shareholders.

Now, environmental advocates say Amazon appears to be on the right path — in contrast to many other major plastic users. Even companies that have signed onto a prominent pledge to reduce virgin plastic use have moved in the wrong direction: Over the past several years, Pepsi, Coca-Cola, Mars, and many others have reported an increase in the weight of their virgin plastic packaging.

Still, the 86,000 metric tons of plastic used in Amazon fulfillment centers is a lot, and Douglass Guernsey, a shareholder advocate for Green Century Capital Management, said Amazon must move much faster to replace other types of plastic packaging — like non-padded plastic mailers — with reusable alternatives or packaging made from recycled paper. He called for third-party verification of Amazon’s single-use plastic reductions, and for the company to disclose more information about its plastics use: “What type of plastic is Amazon using?” Guernsey asked. “How much is designed to be recyclable?”

Guernsey also criticized Amazon for failing to make a forward-looking, time-bound commitment to reduce its plastics use. “I would like them to make a statement saying, ‘We’re phasing out single-use plastic. We’re Amazon, we can do that,’” he said. 

Littlejohn said Amazon should ensure that its plastic reductions manifest throughout the company’s supply chains. Although the numbers cited in Amazon’s 2022 sustainability report likely apply to the majority of Amazon orders — those shipped from the company’s fulfillment centers — they don’t cover those that are shipped from third-party sellers’ doorsteps. Amazon doesn’t disclose what fraction of its sales are shipped from third-party sellers.

Amazon declined to respond to a series of questions about its plastic use, but a spokesperson for the company said they “continue to prioritize materials that are recyclable and to find alternatives to plastic.” The spokesperson noted some of Amazon’s previously published progress, including the elimination of single-use plastic air pillows in Europe and Australia. 

Both Guernsey and Littlejohn vowed to keep campaigning for stronger action from Amazon. “Investors care about this,” Guernsey said. “The shareholder process has been incredibly important … and we’re going to continue to use it to pressure the company to reduce its environmental footprint.”

Wake from a passing barge nearly throws me over the edge of Nelson’s flat bottom boat. He is winching in his gill nets and I am wondering if it is a bad idea for me to try and help him with the day’s catch. It can get dicey, gill netting silver, bighead, and common carp. The silvers and bigheads like to bask in the calmer pockets of water where your nets can get snagged and the common carp prefer to skirt the bank where it’s two or three feet deep, foraging for worms, insects, and whatever else they can find. Losing a net is a big deal too because you can get fined for “ghost fishing,” or catching and killing fish in an accidentally lost net. The electric engine is whining with the weight of the catch though and Nelson keeps saying, “It’s a good day, Benjamin! It’s a good day!” 

Nelson let me borrow his Grundens, which are two sizes too big, but he doesn’t want me to wear his dad’s old gear. He’s the only person who gets that privilege. 

“Fishing coming up,” Nelson shouts. I see it, a bighead, probably twenty pounds. I grab the tail, free its head with the fish pick, and toss it in the front of the boat. It smacks its tail on the deck. “That’s the sound of money,” Nelson yells. He’s one of a dozen or so commercial fishermen who gill net carp on the Missouri River. When the water was dirty, the carp were a constant source of hand-wringing and injury. The silvers have a bad habit of jumping out of the water when scared and colliding with the faces of unfortunate boaters. The Big Muddy is clean now, and Nelson can market his carp in the new KC port. Ramen spots in Westport serve Missouri local fish cakes, a local cajun place uses the meat to make smoked fish dip, and what doesn’t get sold to the food market gets used for fertilizer.

Another bighead surfaces as Nelson pulls in more net. This one is bigger, thirty pounds maybe. I stick its body under my arm like a football, slip the net off with the pick, and heave it into the hold. It goes that way until there are at least fifty fish piled in the bottom of the boat. We’ve nearly pulled in all the net, the marker buoy bobbing towards us, when I see a huge white shape roll at the surface. The tail is a foot tall at least and I recognize the gray and cream coloration. 

“Sturgeon!” I shout. Nelson positions himself to keep the winch going and help me, but then the marker buoy bobs underneath the water and the boat lurches sideways. I hold on to the gunwale, trying to steady myself, and Nelson hits the emergency stop on the winch. 

“Fuck,” he mutters, tugging on the net. “It’s snagged. How is that even possible? We need to get that fish out of the net.” The marker buoy bobs back up then disappears as Nelson gives the net a tug. Neither one of us want to see the sturgeon die, but if we can’t get the net unstuck, it’s a real possibility. I pull with him, but the only thing we manage is to inch the boat backwards.

“Ben, grab an oar. We’re just going to have to swing around and grab it. I can’t risk getting the prop tangled in that net.” He cuts the engine right when I grab an oar. I rush to the helm, slip through the piles of fish, and paddle furiously on port side. I look over my shoulder and Nelson is leaning over the gunwale, a knife in one hand, straining to reach the entangled sturgeon as we turn and drift towards it. Then, he plunges headfirst into the river, the soles of his boots skyward. I scramble back to the stern just in time to see his head pop up above the surface. He takes a deep breath and then starts cutting through the net. His life jacket is barely keeping him afloat and I know that as soon as he severs the connection between the boat and the gill net, he and the sturgeon are going to start drifting down current.

“A fish this size can be a hundred years old, older than the last great flood.”

“Take it in!” he shouts as he cuts the last part of the net. I flip the winch on to take up the last of the net and hit the red button to start the outboard. It sputters, but doesn’t turn over. Nelson is holding on to the sturgeon like a floaty and the two are already going downriver. 

“Blue button then the red button!” he shouts. This time the outboard starts and I circle the boat around. The end of the gill net is still snagged beneath the surface so Nelson and the sturgeon are now being buried by the current. I pull up and engage the spot lock so the boat will hold next to him. I lean over the edge, grab the back of Nelson’s collar, and pull him to the boat. The current is pushing his head forward, but he manages to grab the gunwale and I help pull him onto the deck. He lays on his back for a minute, laughing, water pouring off his clothes. He’s missing a shoe.

With shaky arms, I pilot the boat within arm’s reach of the sturgeon. Nelson rolls over and slaps me on the back. 

“Thanks Ben,” he says. “Thanks.” Together, we pull the sturgeon up next to the boat and I use the fish pick to free it from the net. It’s a six footer, with a dark gray back.

“Everyone thought these were going to go extinct,” Nelson says breathlessly. I cradle its head in my arms and dip it in the water, facing the current so it can revive. A fish this size can be a hundred years old, older than the last great flood. I feel it start to kick, strength returning to it, and I lift the slate-colored head for one last look. Then, we release it back into the river and it disappears into the murky water. Nelson pulls us to the marker buoy and we break it off the snag. We ride in silence to the port at the flooded west bottoms. 

The port flooded back when it was a stockyard in 1951, over a hundred and fifty years ago. They rebuilt it only to have the same flood that swept away KC United Power wipe it out a second time. Now it’s a shallow bayou full of long piers, frog giggers, and houseboats. It floods every year, but people are used to it. We’ve learned to live with the river. 

When we unload the last fish to the processor, Nelson turns to me and shakes his head. He’s still soaked and there’s a scrape on his hand from a fish barb.  

“I thought I was in trouble there for a second. My foot was wrapped up in the net.” He points to his shoeless foot. “My own river damn near killed me.”

“That’s why you love it though, right?” I say. He pulls his shirt off and wrings the water out of it. 

“True words. Maybe you only love rivers that kill you.” 

* * *

Nelson is sipping a beer, splayed out on the gravel bar, watching the drip of the bulkhead across the river. I’m sizing up the ten-pound grass carp he’s tasked me with filleting, which I’ve never done before. I tell people I’m an apostate of vegetarianism, but you’re never supposed to take the word of an apostate. We’re there to eat the inaugural carp celebrating that the Blue River is finally clean enough to eat from. We’re also there because Nelson’s dad died the day before and Nelson said he needed the river. 

“My granddad never told me what that is,” he says, pointing towards it. The bulkhead is a cracked steel door, like in a submarine, but big enough to drive a truck through. Next to it is the remodeled Prospect bridge, and we’re sitting on part of the riverbank that used to be chain-linked riprap. Metal warehouse roofs, lit by LED spotlights, just peak above the old stone wall of the Bannister Federal Complex, a nuclear manufacturing facility that leaked toxic waste into the river in the early 2000s. That was a hundred years ago though. Now, its spongy, erosion-protective grounds store biodegradable straws. Poetry. 

“It’s where they tossed out the dead bodies,” I say. Nelson laughs. He’s wearing his granddad’s muck boots, which have at least six visible holes in them. “You think I’m joking, but what else is an eight-foot-tall cement bulkhead for if not filling up with bodies to be dumped in the river when it floods? Wouldn’t have been the first time they dumped stuff here.” 

“You still working on that fish?” he asks. He looks over his shoulder at the uncut carp, nods, and looks back at the river. “Scale it first, then start at the head, right where the scales would start. Slip the knife between one, flat along the spine.” I do as he says. I slide the back of the knife against the scales, knocking them off. They are quarter sized, like plate armor. I slide the knife down the back bone, crunching through the y-bones that run the length of the fillet.  

I’m Nelson’s protege. In exchange for help running his carp nets on the Missouri I soak up his knowledge of Kansas City. His family is from east of Troost and they know the metro better than anyone. His great granddad was a Black business tycoon and spent all his money buying up the private land on the Blue River. He willed it to the Department of Conservation after his death. His granddad was the river, breathed it, worked next to it, was poisoned by the Bannister Federal Complex. His father was a wildlife biologist, a guerrilla conservationist who snuck into the park to remove invasive honeysuckle when Jackson County couldn’t get their shit together.   

Nelson’s a search engine for the Blue River’s fauna: beavers, deer, mink, you name it. He knows where they live, what they eat, when they fuck for God’s sake. He knows all the other stuff too, wild grapes, how to tell the difference between a blackberry and a dewberry. We pick the chanterelles and other wild mushrooms that hide in the woods, but most often, we’re at the river. I’m his friend now too, which is pretty much unavoidable when you share the river together.

“His granddad was the river, breathed it, worked next to it … “

“You’re getting there,” he says, looking over his shoulder again. He hops up. “This is a special carp, you know?” 

I nod. They used to call them ditch salmon, polychlorinated biphenyls spiderwebbed in their fillets. Every nosing carp that rolled in the Blue River flats was a swimming public health catastrophe. Think melanoma, gall bladder disorders, Chernobyl-style shit. People hated them for it too, like the fish were PCBaholics, eagerly sucking the chemical despite intervention, rehab. There was a whole pamphlet about it, a warning. Grass and common carp, ALL SIZES, don’t eat more than one a month. It wasn’t the fishes’ fault though.

“Goddamnit,” Nelson says under his breath. “I wish…” 

His face twists. His dad should’ve been here to see it. They’d tried to make it happen, but there was no way he could travel.   

“You know, Dad told me today that these boots were all granddad had left when he died. Cancer ate up all the rest of his goddamn life because of this place. I always thought he’d left my dad a little bit of money, but nope. Just these old ass boots.” 

“Did your dad go peacefully?” 

Nelson shakes his head. He has a rod stuck in the bank, a live blue-gill on the other end, hoping to catch a flathead. “Dad wasn’t ever gonna go easy.”

I want to say I’m sorry, but I just nod. His eyes are fixed on the bulkhead. My grandpa had told me about the river too, but not like Nelson. He had grown up in Kansas City, west of Troost, and to them it was a distant catastrophe. He existed outside the redlined Black neighborhoods, floating above the city’s history like it was a documentary and not part of his hometown. When the Troost divide started to melt, the runoff of local memory made its way west, into the white neighborhoods that’d tried to forget. West KC was forced to remember. 

At one time, the Bannister Federal Complex had been the Kansas City Speedway, then a manufacturing facility in the Second World War, an office for the IRS. Before it was shut down, its final iteration was a nuclear manufacturing plant. Airborne toxins started to poison the workers in the active part of the facility, then the office staff, until the administration couldn’t hide behind fudged reports anymore. My granddad heard it on the news, wrote a letter to the city. By that time though, Nelson’s granddad was coughing blood. 

I throw the fish head in the river. Sometimes we keep it for soup, but it’s early summer. Too hot for that. The crayfish will find it, scuttle out from beneath the rocks and recycle it back into the riverbed.

Nelson walks over and crouches above the electric camp stove we brought down to help us fry the fish. He pulls a bag of cornmeal from his backpack, a pot, a glass bottle of oil, a metal camping bowl, and a plate. I score the fillets so he can rub cornmeal in between the gaps to fry the y bones soft. 

The little beep of the burner reminds me of the old propane camp stove my dad still used when I was growing up. The whooshing of natural gas being ignited is nostalgic, but my dad was an ironic hold-out when the natural gas industry shut down. Gasoline and propane disappeared when I was in elementary school. Now, it’s all batteries.  

He puts the pot on the burner and pours an inch of oil in. I stare at the pot as he gently places the fillets in to fry. The sizzling and bubbling of fish mixes with the trickle of the river and the droning of bullfrogs. 

“You really think it’s safe to eat?” I ask. Nelson flips a carp fillet with his fork. 

“You know, when dad found out he was dying, he started coming down here all the time and eating fish. Every day he had the energy he was frying up carp. He said he could feel the river had recovered, heard turkeys again, saw beaver sign. They hadn’t announced the end of the pollution advisory. I just thought he didn’t care anymore since he was going to die anyways.”

“He wasn’t too far off though,” I say. “Fourth of July, two years ago, he talked me and my dad’s ears off about it. I thought it was just talk.”

Nelson grins. “One day, son, it’ll be so clean you can drink it!” he says, shaking his finger at me. “Don’t you stop believing that.”

“My dad tried that after talking to him.”

“No shit,” Nelson says. I laugh and nod. My dad, with his ridiculous panama jack hat, sipping the Blue River on his hands and knees, saying he wanted to reconnect to nature. 

“He got giardia. Puked his guts out. I told him to boil his water next time and he told me to mind my own damn business.”

“Rightly so. It’s a man’s inalienable right to give himself waterborne parasites,” Nelson says. He lifts the fillets from the oil and sets them on the plate. I fish around in my backpack for the spice shaker. A semi silently glides across the Prospect bridge above us, autopilot lights pulsing blue, and I stop to watch it pass. It backlights the box elders and sycamores that separate the road from the riparian forest below. I think back to being a ten year old, clambering through cathedrals of invasive honeysuckle before they figured out how to eradicate it. That world feels thousands of years away. 

I pull my canteen from my pack, dip it in the river, and screw the cap on. Everyone has portable filters now. The water is cold even though it’s June. I offer it to Nelson.

“To life,” I say. He takes it from me, steps into the river, and stares again at the bulkhead door. He raises the canteen then puts it to his lips. To life. 

* * *

The ANGELINA’s hull is only visible in winter, when the mouth of the Blue River runs low at its entrance point into the Missouri. Last year’s floods unearthed the bridge, which Nelson and I had seen just peak above the water’s surface in the fall. We are floating down the Blue River, intending to be the first to search the long abandoned vessel.

Nelson and I dig our paddles into the flow so that we’ll beach on the sandbar where we think we can climb into the control deck. KC United Power used to own the mouth of the Blue, until a hundred year flood destroyed the station, buried Bayer’s Crop Science institute in a foot of silt and deadfall, and created an oxbow lake between Blue River and Rock Creek. Most of the old floodplain is now public land or Department of Conservation-leased crop fields. 

Duck hunters call in the distance and I hear the whistle of gliding waterfowl above me. Nelson puts a hand to his ear, nods, and we hear one, two, three shotgun blasts in quick succession. It’s probably Stuart Mills and his friends. They are the most faithful congregants around the backwaters near downtown. Stuart is in his seventies, grew up east of Troost, before the flood, and used to drive three hours to try to find waterfowl. We met him at the boat ramp upstream two years ago. It’s a yearly event to ride with Stuart in his busted up jon boat and watch him hobble to the duck blind with his equally ancient black lab. They always come home with ducks. Everyone does now. 

After the flood, the Missouri finally chewed up enough wing dikes to slow and widen. It was a renaissance for wildlife and the Corps of Engineers decided that their sonar mapping was good enough to let the river breathe again. Now, the urban core who’d lived generations disconnected from the cottonwood bottoms and marshes that the first humans would’ve found alongside the Big Muddy have rediscovered the river. 

* * *

Nelson and I slip out of our kayaks and haul them onto the sandbar. It’s the kind of sand that you only find in rivers, the kind you can sink into, that finds its way between your fingers and behind your ears. Nelson reaches the rusted sides of the barge first. 

“It’s bigger than I thought,” he says. The deck is a good fifteen feet in the air and the hull angles slightly away from us. I uncoil a ratchet strap and toss it onto the ship. Careful does it. I pull it back until the hook end of the strap catches one of the portside cleats.

“You wanna test it?” I ask Nelson, handing him the strap. He shrugs and gives it a sharp pull. “If I break my leg, you have to tow me back, you know.”

“Tow you my ass. You paddle with your arms, not your legs,” I say, grinning. Nelson grabs the strap and starts climbing. He’s got those farmer hands from running his commercial gill nets. Most everyone does something with their hands these days though. My specialty is lion’s mane mushrooms.

Once Nelson clambers over the gunwale, he unhooks the strap and wraps it around the cleat so there’s no way it’ll slip off. I give him a thumbs up and grab the rope. River barges are shaped like big tubs and normally there’d be another fifteen foot drop off the other side of the gunwale, but it’s mostly filled up with sand. We follow the steel frame to the bridge.

The ANGELINA was the last of the old barges and a rare model. It was one of only a few manufactured with an inboard tug. When we reach the rusted stairs, Nelson says after you and steps aside. The stairs lead up to the main deck of the tug. The crew quarters and navigation room are more or less a metal shipping container on top of another shipping container that holds the engine. 

“I want to break the lock, see what’s inside, but there’s a feeling, like I’m trespassing.”

“Thanks,” I murmur. I test my weight on the first step and it holds. The whole frame groans and creaks under my weight, but I make it to the top. My hands are caked red with rust from the railing. Nelson follows and we peek our heads into the door. There’s otter poop everywhere, and frozen, half-eaten fish carcasses.

“Amazing that the sonar screens aren’t cracked,” Nelson says. He tries to turn the faded silver steering wheel, but it won’t budge. Time and water have eroded the paint off the control buttons. I open a few cabinets next to the crew bunks. There’s a sealed plastic bag with a phone in it, the kind that my grandpa used to have. I turn it over in my hands and then put it back in the cabinet. 

“Got something juicy here,” Nelson calls out. There’s a cabinet with a padlock on it. He gives it a tug, but it won’t open. “Damn. Should we try to break it?”

I want to break the lock, see what’s inside, but there’s a feeling, like I’m trespassing. Nelson must feel the same because he gives it up and after we rummage around, he shrugs and says, “I’d say, let’s take some pictures and head out. Nothing much here unless you want to see what’s in the engine room.

“Worth checking out,” I say. We open the door, but it’s mostly filled with sand. I turn to leave, but catch the shape of something sticking out of the silt underneath one of the engine room stairs. I pull it out and bring it to the front of the tug where I can get a good look at it. 

“Is that a Hot Wheels?” Nelson asks, looking over my shoulder. I turn it over in my hands. It’s a truck, a Ford I think. I look at the bottom of it and F-150 Electric 2024 is embossed on the cast metal underside. 

“Holy shit,” I say. “This is from when my grandpa was a kid. Looks like a first edition too, right when everyone went electric.”

“That might be worth something,” Nelson says. “Why do you get to find the cool stuff? Goddamnit. Maybe I will break that lock.” I walk out onto the deck while Nelson looks around more. The silhouettes of migrating mallards break the horizon and I hear a few more shots from where Stuart and his arthritic dog are undoubtedly huddled behind the cattails. I slip the toy truck in my pocket and sit on the starboard edge of the deck. 

“Yes!” Nelson shouts from inside the tug. I turn and see him come out with a broken padlock. 

“You couldn’t resist,” I laugh. 

“You can’t find all the cool stuff. Come look,” he says. I hop up and we both crouch in front of the cabinet. It’s rusted shut and Nelson has to grab the handle with both hands and press against the wall with his feet. It pops open and the hinges snap, leaving Nelson flat on his back with the door in his hands. Nelson tosses the door to the side. A tattered, canvas backpack is shoved inside. He slowly works it out, but even being careful the fabric rips a bit. When he tries to unzip it, the bag rips more. 

“You’re a top notch archeologist,” I say. He grimaces and after some more unintentional ripping, opens the bag. Inside it is another half gallon plastic bag. 

“Why did everyone on this boat put their stuff in plastic bags? It’s like they knew it would sink.” He opens the plastic and inside is a buck knife, a yellowed copy of Sand County Almanac, and a duck call. Nelson looks up and smiles at me. 

“Don’t even say anything,” I say. 

“Oh, I won’t. You just keep that Hot Wheels of yours.” He puts the bag and the busted lock back in the cabinet, shoves the door in, and walks out onto the deck. I follow, wishing I had opened the lock first. He puts the duck call to his mouth, cups the end of it with his hand, and rips out the loudest mallard quack he can muster. We wait and after a minute we hear a distant quack return. 

“That’s probably Stuart,” Nelson says. He gives the call one more go, then we climb down the stairs, rappel off the barge, and walk back to our kayaks. Nelson gathers washed up wood and we build a small fire. Close to dark we stomp it out and paddle back upstream in the dark, treasures in tow, the low glow lights of downtown KC sparkling like distant fireflies.

‘Underground Climate Change’ Is Shifting Chicago’s Foundations, Study Finds

Climate change is causing global temperatures to rise, leading to droughts, heat waves and wildfires. It is warming the surface of the ocean, intensifying hurricanes and increasing acidity and ecosystem imbalances.

But the climate crisis is also happening beneath our feet, in a phenomenon called “underground climate change.”

The concept has been studied for years surrounding issues of railroad tracks buckling in the heat and groundwater contamination, according to CNN.

However, it was not until recently, in a new study by Alessandro F. Rotta Loria, an assistant professor of civil and environmental engineering at Northwestern University, that the effects of underground climate change — also known as “subsurface heat islands” — on civil infrastructure were examined, a press release from Northwestern University said.

“Underground climate change is a silent hazard,” said Rotta Loria in the press release. “The ground is deforming as a result of temperature variations, and no existing civil structure or infrastructure is designed to withstand these variations. Although this phenomenon is not dangerous for people’s safety necessarily, it will affect the normal day-to-day operations of foundation systems and civil infrastructure at large.”

The study, “The silent impact of underground climate change on civil infrastructure,” was published in the journal Communications Engineering.

When the ground gets hotter, it can expand, contract and become misshapen, causing the foundations of buildings to move and sometimes crack. This can affect the soundness and performance of the structures.

“Chicago clay can contract when heated, like many other fine-grained soils. As a result of temperature increases underground, many foundations downtown are undergoing unwanted settlement, slowly but continuously. In other words, you don’t need to live in Venice to live in a city that is sinking — even if the causes for such phenomena are completely different,” Rotta Loria said.

Earlier research discovered warming of 0.1 to 2.5 degrees Celsius each decade for cities’ subsurfaces.

“If you think about basements, parking garages, tunnels and trains, all of these facilities continuously emit heat,” Rotta Loria said in the press release. “In general, cities are warmer than rural areas because construction materials periodically trap heat derived from human activity and solar radiation and then release it into the atmosphere. That process has been studied for decades. Now, we are looking at its subsurface counterpart, which is mostly driven by anthropogenic activity.”

Rotta Loria and the research team installed more than 150 above and below ground wireless temperature sensors along the Chicago Loop. The researchers placed them in subway tunnels, basements, subsurface streets and underground parking garages. They also buried some in Grant Park for comparison.

The team found that the temperatures under the Chicago Loop were frequently 10 degrees Celsius warmer than those under Grant Park.

Underground air temperatures can be as much as 25 degrees Celsius hotter than the temperature of intact land, potentially leading to problems of warping, cracking and people using the structures getting heat stroke.

“We used Chicago as a living laboratory, but underground climate change is common to nearly all dense urban areas worldwide. And all urban areas suffering from underground climate change are prone to have problems with infrastructure,” Rotta Loria said.

Rotta Loria completed a 3D computer model after three years of collecting temperature data that was able to simulate how subterranean temperatures had evolved since 1951 — the year the city finished its subway tunnels. The values were comparable to the field data, so Rotta Loria used those to predict the evolution of temperatures until 2051.

Rotta Loria also came up with a model for the deformation of ground in response to rising temperatures. Materials like stiff and soft clay contract when they are heated, while materials such as limestone and hard clay expand.

The simulations showed that warmer temperatures can lead to ground expanding and swelling by up to 12 millimeters. Increased temperatures can also lead to ground contraction and sinking beneath a building’s weight by up to eight millimeters. It may not sound like much, but it is more than many foundations and components of buildings can take and still function.

“Based on our computer simulations, we have shown that ground deformations can be so severe that they lead to problems for the performance of civil infrastructure,” Rotta Loria said in the press release. “It’s not like a building will suddenly collapse. Things are sinking very slowly. The consequences for serviceability of structures and infrastructures can be very bad, but it takes a long time to see them. It’s very likely that underground climate change has already caused cracks and excessive foundation settlements that we didn’t associate with this phenomenon because we weren’t aware of it.”

Rotta Loria emphasized that newer buildings fare better than older ones.

“In the United States, the buildings are all relatively new. European cities with very old buildings will be more susceptible to subsurface climate change. Buildings made of stone and bricks that resort to past design and construction practices are generally in a very delicate equilibrium with the perturbations associated with the current operations of cities. The thermal perturbations linked to subsurface heat islands can have detrimental impacts for such constructions,” said Rotta Loria.

Rotta Loria pointed out that building planners can minimize the amount of heat that goes into the ground by installing thermal insulation.

“The most effective and rational approach is to isolate underground structures in a way that the amount of wasted heat is minimal,” Rotta Loria said in the press release. “If this cannot be done, then geothermal technologies offer the opportunity to efficiently absorb and reuse heat in buildings. What we don’t want is to use technologies to actively cool underground structures because that uses energy. Currently, there are a myriad of solutions that can be implemented.”

‘Now Is the Time’ to Curb Energy Emissions as Demand Rebounds, IEA Expert Says

Global energy demand will increase next year, and we will need more renewables capacity as fossil fuel-generated power slows — that’s the message from a new International Energy Agency (IEA) Electricity Market Report.

Slower economic growth and the global energy crisis are predicted to ease the demand for global electricity this year, but next year it will again pick up pace as the economic outlook improves, rebounding to 3.3 percent, according to the report.

This year’s demand is expected to increase by less than two percent, down from 2.3 percent in 2022. The average yearly growth rate from 2015 to 2019 was 2.4 percent.

“The world’s need for electricity is set to grow strongly in the years to come. The global increase in demand through 2024 is expected to amount to about three times the current electricity consumption of Germany,” said Keisuke Sadamori, the IEA’s director for Energy Markets and Security, in a press release from the IEA.

The IEA said renewable energy will be able to cover predicted growth through next year, as renewable sources will make up more than one third of the world’s supply of power for the first time in 2024, reported Reuters.

Electricity demand in the European Union (EU) is expected to fall to its lowest level in two decades this year, but renewables growth will be important as the economy and energy needs ramp up again, the press release said.

In the United States, it is predicted that demand for electricity will decrease by nearly two percent in 2023. In Japan and the EU, demand is set to fall by three percent. The drop in EU demand this year, along with a similar decrease in 2022, add up to the largest slide ever recorded, with consumption in the EU set to fall to 2002 levels.

Over the next two years, energy demand in China is predicted to go up at an average yearly rate of 5.2 percent, which is just below the average for 2015 to 2019. In India, average yearly demand is expected to grow an estimated 6.5 percent through next year, which is far higher than the country’s average for 2015 to 2019.

There is enough renewable energy supply to meet additional demand for electricity worldwide through 2024.

While renewables are making up more of global energy capacity, over the next two years, fossil fuel-based electricity is predicted to fall. Power from oil is expected to decrease markedly, and coal-fired power is projected to decrease slightly this year and next.

The IEA also shows fossil fuel-generated electricity decreasing in four of the years from 2019 to 2024.

Until recently, yearly declines in fossil-fuel powered energy usually only happened following global financial and energy shocks that led to a fall in worldwide demand. Now fossil-fuel generated electricity slows or decreases as power needs grow.

According to the IEA, this shows that the planet is quickly approaching a “tipping point” when clean energy will take the place of fossil fuels more and more.

“[W]e’re encouraged to see renewables accounting for a rising share of electricity generation, resulting in declines in the use of fossil fuels for power generation. Now is the time for policy makers and the private sector to build on this momentum to ensure emissions from the power sector go into sustained decline,” Sadamori said in the press release.

The report found that energy-intensive industries in the EU have yet to rebound from the production slump of 2022, and that heightened energy costs that followed Russia’s invasion of Ukraine led to nearly two-thirds of EU electricity demand reduction last year. This has continued this year, even though electricity and energy commodity prices have gone down.

Canadian Lake Chosen as Site to Mark Beginning of Anthropocene Epoch

Following years of discussions by scientists on how and when humans began to significantly alter the planet, Canada’s Crawford Lake has been chosen to mark the beginning of a new geological epoch: the Anthropocene.

The International Union of Geological Sciences had to select one site that symbolized humans’ enormous effect on Earth before the new era could be officially declared, reported Yale Environment 360.

Each year, particles collect on the tranquil, 79-foot-deep lake and settle to the bottom to form strata of sediment that become a record of the environmental conditions of that time, much like tree rings, according to the journal Nature. If the scientists’ choice is approved, a core of sediment from the lake — located in a conservation area in Ontario — will become the “golden spike” to mark the start of the Anthropocene.

“The sediments found at the bottom of Crawford Lake provide an exquisite record of recent environmental change over the last millennia,” said Simon Turner, a researcher at University College London, in a statement. “It is this ability to precisely record and store this information as a geological archive that can be matched to historical global environmental changes which make sites such as Crawford Lake so important.”

Sediments on the lake’s bottom include evidence of Indigenous Peoples, European settlers, ash from the burning of fossil fuels, nitrates from chemical fertilizers, logging and radioactive plutonium-239 from the testing of nuclear weapons, according to Yale E360, Nature and The Guardian.

“[T]here are no burrowing organisms to disturb the sediments, allowing the precise calendar age of sediments to be determined by layer counting, just like tree rings,” Francine McCarthy, a scientist at Brock University in Ontario, told Yale E360.

Other locations in the running for the origin of the golden spike included a Gulf of Mexico coral reef, a Polish peat bog and the Antarctic ice sheet.

In 2016, the Anthropocene Working Group (AWG) decided that humans had had such an impact on the planet that it was time for a new geological epoch, The Guardian reported. 

The current geological epoch, the Holocene, began 11,700 years ago, following the last big Ice Age. All of human civilization developed during the Holocene, which was marked by global environmental stability, allowing many plant and animal species to flourish.

If Crawford Lake is approved as the site of the beginning of the Anthropocene, the new geological epoch will officially be declared in August of 2024.

Hallmarks of the Anthropocene include climate change, plastics pollution and devastating impacts on wildlife.

Plutonium isotopes from hydrogen bomb tests have been selected by the AWG as the main marker of the new epoch. The isotopes were spread around the world beginning in 1952, then decreased quickly following the 1963 Nuclear Test Ban Treaty.

“The Anthropocene that starts in the 1950s represents a very rapid change that we have caused to the planet. There’s hope in that respect. The combined impacts of humanity can be changed rapidly for good and for bad. It’s not inevitable that we have to slide into continuing environmental poverty,” said AWG Chair Professor Colin Waters from the University of Leicester, as reported by The Guardian.

Biden Declines Call to Embargo Products From Mexico Over Endangered Vaquita Crisis

President Joe Biden has decided against imposing an embargo on products from Mexico after the country was sanctioned by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) for failing to protect vaquitas by curbing illegal totoaba fishing.

Vaquitas are critically endangered porpoises with only about 10 individuals left in the population. They have faced threats from illegal fishers, who use gillnets to trap totoaba, a type of fish whose swim bladder is used in traditional medicines and foods and can sell for thousands of dollars per pound. It is illegal to fish for totoaba, but people have continued illegally fishing for them in protected areas. The vaquitas can die from entanglements in the gillnets.

CITES sanctioned Mexico in March 2023 for failing to stop illegal totoaba fishing and thereby failing to protect the few remaining vaquitas left. 

In May of this year, Secretary of Interior Deb Haaland certified that Mexico was involved “in trade or taking that diminishes the effectiveness of any international program for the conservation of endangered or threatened species,” under the U.S. Pelly Amendment. 

Haaland cited that Mexico has failed to abide by CITES Appendix I, which makes trade of both totoaba and vaquita parts illegal.

With this certification, Biden was given until July to decide whether or not to take action against Mexico, the Animal Welfare Institute reported.

“Mexico has failed the vaquita and ignored its obligations under international law, so this step is crucial,” Sarah Uhlemann, international program director at the Center for Biological Diversity, said in a statement. “No one relishes painful trade sanctions, but without strong, immediate pressure from the international community, there’s a good chance we’ll lose this shy little porpoise forever.”

Biden announced on July 17 that he would not move forward with a trade embargo, instead noting that other actions — such as having executive department and agencies carry a dialogue with Mexico about next steps to reduce illegal fishing, assisting Mexico in complying with CITES measures, and having the Department of the Interior develop an assessment over the next year on Mexico’s actions to enforce the CITES Compliance Action Plan — were sufficient.

The President noted he will reassess the situation in one year and said potential trade restrictions may be possible next July without improvements on curbing illegal fishing.

“I’m disappointed in the U.S. government for doing so little to save vaquitas from extinction,” Uhlemann said in a statement. “These are the rarest marine mammals in the world, and yet the United States has let the Mexican government off the hook again. Mexico has a long, painful history of failed promises on protecting these little porpoises. The United States needs to apply the strongest pressure and ban seafood from Mexico until there’s real enforcement on illegal fishing in their habitat. The last 10 vaquitas are at stake.”

Arctic Sea Ice 101: Everything You Need to Know

Quick Key Facts

  • Temperatures in the Arctic are increasing four times faster than the rest of the planet.
  • The main driver of Arctic sea ice decline is human-caused global warming.
  • Sea ice reflects about 50 to 70 percent of incoming solar energy, while the much darker surrounding ocean only reflects about six percent.
  • Most multiyear sea ice is fresh enough to drink, as the salt drains through the ice leaving fresh water behind, which is often used for polar expeditions.
  • The Arctic is the only place polar bears are found on Earth.
  • The record low for Arctic sea ice extent — 1.32 million square miles — was set on September 15, 2012.
  • The planet loses Arctic sea ice at a rate of nearly 13 percent every ten years.
  • In the past three decades, the thickest and oldest Arctic ice has declined by 95 percent.

What Is Arctic Sea Ice?

Sea ice forms and covers most of the Arctic Ocean during the shorter, darker winter months. How much of the ocean’s surface is covered in sea ice is an important indicator of climate change. By mid-September, after the summer melt, the area covered by Arctic sea ice will have reached its thinnest — about half the maximum area covered in winter.

In the polar regions, the sun’s rays strike the surface of the Earth at an angle that is more grazing than the more direct angle experienced in regions near the equator. This is the primary reason for the cold weather at the poles and the warm weather in equatorial regions.

Sea ice keeps the polar regions cool by reflecting sunlight, as well as by acting as a layer of insulation between the cold air above and the warmer water beneath it. By doing so, sea ice helps to maintain the energy balance of our planet.

As Earth’s temperatures rise, scientists are able to measure the rate at which the warmer air and water temperatures reduce the amount of measurable sea ice. They have found that the maximum amount of sea ice has been shrinking at an alarmingly rapid pace.

Why Is Arctic Sea Ice Important? Why Does It Matter?

Human Impacts

The melting of Arctic sea ice can have enormous impacts on humans. It can lead to extreme weather changes that can cause drought, heat waves, flooding and wildfires, displace people from their homes, increase human-wildlife conflict, disrupt food systems and alter the shipping routes used to transport goods all over the world.

Coastal Communities

Despite what many people may think, the melting of Arctic sea ice does not contribute greatly to sea level rise. This is because it is sea water that has frozen, so, like an ice cube, when it melts it doesn’t change the overall water level.

As Arctic sea ice melts, its coastlines become exposed to the open ocean, making them more vulnerable to larger storm-generated waves. This can lead to accelerated coastal erosion, which impacts the environment, including human and wildlife habitats. The erosion releases soil, salt, nutrients and sediment into the ocean, which can carry pollutants from the land with it. This can cause negative impacts for animals who live on the beach and in coastal waters. Coastal erosion can also damage rail and road transportation infrastructure, and sedimentation changes along coastlines can impact navigation routes.

Unlike the melting of Arctic sea ice, when ice on land from the Antarctic or Greenland ice sheets melts it can contribute significantly to sea level rise. This is because ice that was previously frozen on land makes its way to the ocean, adding to its volume.

The melting of Greenland’s ice sheet contributes to sea level rise at the rate of at least 0.5 millimeters annually, and recent studies suggest the rate may be speeding up. If all the ice on Greenland were to calve into the ocean or melt, sea levels around the world would rise 23.6 feet.

Food Supply

The unpredictability of rapidly changing temperatures and weather patterns — like polar vortexes and heat waves — associated with the loss of Arctic sea ice and the climate crisis can result in damage to crops that supply the world’s food, inevitably harming vulnerable populations the most.

Shipping

The Arctic Ocean is the shortest shipping route between Asia and Europe, but it is usually impassable. However, as Arctic ice melts, new shipping routes are created. During part of the year, some routes have already started to open because of declining sea ice.

These unexplored pathways not only open up possibilities for saving time, but also increase the potential for increased shipwrecks and oil spills in areas that could be difficult for crews to access.

More shipping traffic also means an increase in noise pollution that is stressful to wildlife, as well as increased debris that presents hazards for migratory animals like whales.

Salinity

As ice forms, it becomes less salty as the freezing process expels salt into the surrounding water. The older the ice is, the fresher it is on the surface. When pools of melted water form on multiyear ice, it can be fresh enough to drink.

Since it is less dense, fresh water tends to stay on the surface of the ocean. This lower density water failing to sink at the poles influences ocean circulation, making it more difficult to move warm water northward from the equator. Stagnation can result, affecting the planet’s climate.

Permafrost

Arctic ice and the thick, permanently frozen subsurface layer of soil known as permafrost — made up mostly of plant material in the soil, called “organic carbon” — store large amounts of greenhouse gases like methane and carbon dioxide, major contributors to climate change.

As permafrost thaws and these greenhouse gases are released, the rate of planetary warming increases. As Earth’s temperatures rise further, more permafrost and ice thaw or melt, releasing even more greenhouse gases, and the cycle continues at an even greater pace.

Biodiversity Impacts

For some animals, like Arctic foxes, polar bears, snowy owls, walruses, caribou and other species, sea ice is the only home they’ve ever known. As the ice shrinks, so does their habitat, and they must adapt quickly to survive.

As Arctic sea ice disappears, it brings humans and wildlife into more frequent contact as animals wander into Arctic communities searching for sustenance and refuge as their natural habitat melts away.

Benefits of Arctic Sea Ice

Cools the Planet

The Arctic and Antarctic act as the planet’s cooling system. Ice and snow reflect about 80 percent of the sun’s rays back into space, maintaining the extreme low temperatures of the region and balancing out hotter parts of the planet that absorb heat from the sun.

The less ice there is, the less it is able to act as a reflector, which increases the chance of more global heat waves. The more of the ocean that is exposed, the more its darker waters can absorb solar energy, which leads to higher temperatures and a cycle of warming and melting. It can also result in more extreme winter temperatures, since warmer air destabilizes the polar jet stream, bringing cold air further south.

Insulates

Sea ice forms an insulating barrier, separating the cold air in the atmosphere above from the warmer ocean waters below. This “blanket” keeps both the warm and cold air where they should be, helping to maintain Earth’s energy balance and prevent atmospheric warming.

Heat can escape from the ocean through thin ice or fractures, called leads. About half of the exchange of heat between the Arctic Ocean waters and the atmosphere is due to warm air escaping through openings in the ice cover.

The thinner the ice and the more leads the sea ice has, the less effectively it can provide insulation between the ocean and the atmosphere. This causes the Arctic atmosphere to warm, which affects global atmospheric circulation and weather.

In a process called thermohaline circulation — known as the Great Ocean Conveyor Belt — heat is transported from the equator to the poles. As warm water moves north, it cools, becoming heavier and more dense, which causes it to sink. The water then moves south before rising near the equator, completing the cycle. This natural process helps to balance out Earth’s temperatures. For instance, it keeps Europe relatively warm for its latitude.

Provides Vital Habitat

Arctic sea ice is home to many types of animals, inducing polar bears and narwhals. The ice provides a birthing and resting place for walruses and seals, a place for polar bears to breed and a foraging ground for Arctic foxes, caribou and other mammals. As sea ice melts, so do habitats, and a lack of sea ice can lead to extinction for some species, as they are unable to hunt and reproduce effectively.

If the ice pack shrinks past the edge of the continental shelf — where walruses usually feed — they are forced to swim as much as 250 miles round trip to their feeding grounds, or otherwise crowd together onto small islands or shores.

When Arctic foxes aren’t able to migrate onto the ice, they can become stranded onshore with predators. And some migrating caribou have fallen through ice that was thinner than usual.

Some species of seal are so linked to the ice that their entire existence depends on it. Harp seals live on the edge of sea ice year-round, migrating south in the spring to follow it. Since the beginning of the satellite record, sea ice cover in harp seal breeding habitat has declined. Ringed seals give birth on the ice, which must be sufficient and stable enough for them to build birth lairs and rear their pups. A decrease in sea ice extent reduces seal habitat, and an early breaking up of the ice could mean premature separation of mothers from their pups.

Polar Bears

Polar bears are found in only one place on the planet — the Arctic — where they are apex predators and the largest land carnivore.

For polar bears, thick, stable ice that has been building up for years is the preferred habitat for hunting their main food source: bearded and ringed seals. They eat very little in the summer months while they wait for the ocean waters to freeze again. In some areas, like Hudson Bay, all the bears come ashore during the summer and early fall.

Polar bears can swim, but they don’t often swim too far from land, so lack of sea ice cover means they are forced to swim distances between the edge of the pack ice and land that can sometimes prove too far.

Phytoplankton

The cycle of melting and freezing water in the Arctic keeps the life there healthy, from phytoplankton — an essential food source for marine creatures — to whales.

When ice crystals form on the surface of the ocean, they expel salt that sinks to the bottom. In other parts of the ocean, waters rise, bringing forth nutrients essential to the phytoplankton. When this melt-freeze cycle is disrupted, so is the sustenance of many ocean animals.

Indigenous Peoples

For millennia, the Arctic has been home to populations of Indigenous Peoples — currently about one million — many of whom live along the region’s coasts. For many of these communities, the sea ice is the coastline’s protector from strong winter storms, and an extension of the land used for travel and hunting, as well as to access fish, seals, walruses, whales and other marine life. If sea ice melts too fast in the spring, it leads to a shorter hunting season.

For Indigenous populations, shrinking sea ice means the loss of their homeland. It also affects weather patterns, animal migrations and causes other environmental shifts — patterns that are the bases of their livelihoods and culture.

Less sea ice means fewer animals migrating to Indigenous areas, which means Indigenous Peoples must alter ancient hunting practices. Thinning ice also means more cracks, causing safety concerns. Weather could once be predicted through observations of natural patterns, but now it shifts so quickly and those methods are not always as reliable as they once were.

Since the Indigenous Peoples of the Arctic have such intricate knowledge of sea ice — some of which is passed down through songs and stories — they can provide local observations and fill in missing information and knowledge that can be important to ongoing research on how the region is being altered by climate change. In fact, Bering Sea Elders authored a chapter of the Arctic Report Card for the first time in 2019.

Threats to Arctic Sea Ice

Climate Change

The main cause of Arctic sea ice decline is human-caused global warming. Human activities such as the burning of fossil fuels and industrial agriculture increase emissions of greenhouse gases like carbon dioxide and methane that trap heat in the atmosphere, causing Earth’s temperatures to rise. Temperatures in the Arctic are increasing at four times the rate of the rest of the planet — a phenomenon known as Arctic amplification. Methane is the second most prevalent greenhouse gas and a major cause of Arctic amplification. Methane traps heat in the planet’s lower atmosphere at about 25 times the rate of carbon dioxide.

Until we curb our use of fossil fuels and revert to more regenerative livestock and farming practices, global warming and its consequences will continue.

Sea ice extent has been declining every decade since satellites started monitoring sea ice conditions almost continuously in November 1978. The smallest declines are seen in April, while the largest declines occur in September.

The record low for Arctic sea ice extent is 1.32 million square miles, set on September 15, 2012.

Newly formed sea ice can be extremely thin, but over time it thickens and becomes multiyear ice about 12 to 15 feet thick. Since the 1950s, however, Arctic sea ice has been getting thinner and younger.

A study found that 35 percent of the ice pack in the Arctic in 1987 was a minimum of four years old, with one-fourth of that ice being at least nine years old. But by 2020, almost none of the ice was a minimum of nine years old and less than five percent was at least five years old.

Now, more and more ice is first-year ice about three to six feet thick, as multiyear sea ice keeps declining.

Arctic Amplification

The poles are the most sensitive regions to climate change on Earth, so even a small increase in the average temperature of our planet can lead to greater warming over time.

Arctic amplification is the increasingly sped-up level of warming that is taking place in the Arctic compared to the rest of the world. It operates as a feedback loop: The warmer it gets the worse the amplification gets, which leads to more ice melt and further amplification. In turn, this cycle leads to accelerated climate change for the rest of the planet.

New research has suggested that sea ice melt is the factor most contributing to Arctic amplification.

As permafrost in the Arctic thaws and dries out, grasslands become more susceptible to wildfires, which cause more greenhouse gases to be released into the atmosphere.

At midlatitudes, soot or “black carbon” from wildfires can travel through the atmosphere and land on sea ice, darkening it and speeding up its melt. A 2021 study found that wildfires may be sending three times more black carbon to the Arctic than had been predicted by climate models.

Industrialization and Oil and Gas Activities

Oil and gas activities in the Arctic like the recently approved ConocoPhillips’ Willow project continue the extraction of fossil fuels at a time when the climate-warming emissions they produce — which are ultimately causing the melting of Arctic sea ice — should be reduced and eliminated.

The new shipping routes created by the melting of sea ice also make the region more accessible for fossil fuel energy firms.

Fossil fuel activities wreak havoc on the Arctic ecosystem, disrupting Indigenous communities and the daily lives and migratory patterns of native wildlife. These enormous projects decimate habitat and put local inhabitants at risk from the devastating consequences of oil spills, which are far too common in what would otherwise be pristine wilderness.

More than two dozen oil fields litter Alaska’s North Slope, including Prudhoe Bay, the largest oil extraction project in Alaska thus far. In operation since 1977, Prudhoe Bay is about 250 times as large as Central Park in New York City.

The Alaska Department of Environmental Conservation has said that, since 1996, the oil fields of Prudhoe Bay and the Trans-Alaska Pipeline have averaged 500-plus oil spills per year on the North Slope.

In addition to oil and gas projects, other forms of industrialization plague the Arctic. Factories dot the coastline of Russian Siberia, where toxic pollutants sink into the local environment and are trapped by sea ice, which circulates them throughout the region.

Microplastics from the breakdown of industrial waste and consumer products can be found throughout the Arctic sea ice and seawater below. These tiny plastic particles can come from fishing gear and other human-generated sources.

What Can We Do to Support Arctic Sea Ice?

As a Society?

The best thing humans can do to support Arctic sea ice is to reduce, and eliminate as quickly as possible, the use of fossil fuels and replace them with renewable energy sources. We must do this in order to limit global heating to a maximum of 2.7 degrees Fahrenheit to prevent the worst effects of climate change.

We must also eliminate industrial agriculture and factory farming operations and replace them with sustainable, regenerative agricultural practices on smaller, organic farms.

In the meantime, helping wildlife, ecosystems and communities adapt to the changes we’re already experiencing is also important.

In Our Own Lives?

Reducing our own carbon footprint by driving less, opting for renewable power sources, buying local and organic produce, growing our own fruits and vegetables using regenerative practices, eating less meat, helping our communities start gardens and participating in groups interested in coming up with ways to make our communities greener are all ways to help curb global warming and support Arctic sea ice.

We can vote for leaders who are willing to put policies into practice that will help us make the fastest transition to renewable energy. We can also support businesses that are working to reduce their carbon footprints, and not patronize those that have ties to fossil fuel interests.

Takeaway

Rising temperatures in the Arctic and the shrinking of sea ice maximum extent are indicators of the progress of climate change. Temperatures in this unique ecosystem are heating up nearly four times faster than on the rest of the planet, which means time is of the essence when it comes to slowing global heating, by curbing our use of fossil fuels and our reliance on industrial agriculture in order to avoid the worst effects of climate change.

If emissions continue to rise unabated, there could be no ice left during Arctic summers by 2040. We must act now before it’s too late to stop the feedback loop of Arctic amplification and sea ice melt from destroying our planet’s natural cooling system.
