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.

Why Florida’s home insurance crisis isn’t going away

It’s hard to make money selling home insurance in Florida. For one thing, the state is very vulnerable to hurricanes, and those hurricanes are getting stronger thanks to climate change. That means that insurance companies often have to pay out billions of dollars to rebuild homes after big storms. For another, a legal loophole has made the state a hotbed for fraudulent litigation over insurance claims, and companies lose even more money fighting those lawsuits. Furthermore, these companies have to buy their own insurance from multinational corporations called reinsurers — and reinsurers are charging a lot more money these days, due in part to the increasing severity of hurricane damage.

This difficult environment has made Florida one of the most expensive states in the country for property insurance, with prices about four times as high as the national average. Despite sky-high prices, however, most insurers still can’t turn a profit. The financial pain for the industry got a lot worse last year thanks to Hurricane Ian, which slammed into the city of Fort Myers as a Category 4 storm and caused at least $60 billion in insured losses — more than any U.S. disaster since Hurricane Katrina in 2005. 

That’s been too much for some companies to bear. At least eight Florida carriers have gone bankrupt in the past two years. And just last week two major national insurers, AAA and Farmers, announced that they would trim their business in the state, pulling back from risky areas. The moves may jeopardize as many as 100,000 policies in the state. That’s around 2 percent of the entire state’s market.

“It is pretty rare to have this many insurers leaving a state at a similar time,” said Matthew Palazola, an insurance analyst at Bloomberg Intelligence who studies the Florida market. “Any of these companies leaving probably wouldn’t be hugely significant normally, but it’s more significant with the tide of leaving we’ve seen.”

These departures have forced more Floridians to buy insurance from a state-backed program called Citizens. The program is meant to be an “insurer of last resort” for people who can’t get coverage elsewhere, but it’s ballooned to record size this year as more private companies leave the state. By the end of the year it may have 1.7 million customers. In some areas like hurricane-prone Miami, more than two-thirds of homeowners depend on it.

Florida’s Republican leadership has tried to play down the recent departures as a blip, arguing that the industry is stable and that Citizens’ growth is temporary. The state’s chief financial officer, Jimmy Patronis, called Farmers “the Bud Light of insurance” in what appeared to be an attempt to suggest that its decision was politically motivated. Governor Ron DeSantis, meanwhile, insists that the market is on the mend thanks to recent reforms: Last year, the Florida legislature cracked down on fraudulent litigation and created a new fund to help companies buy reinsurance, which experts believe will stall further bankruptcies. 

“It’s hopefully optimistic, but I think it still will take a long time,” said Palazola. “I haven’t heard any [insurers] say, ‘Oh, they put these reforms in place, that’s great, we’re all in.’ I’ve heard them say, ‘Let’s wait and see.’” Litigation has started to decline since last year’s reforms took effect, and if the trend continues some companies may come back to the market, but no one’s sure how well the new laws are working.

Even if Florida avoids a total market collapse, insurance prices are going to remain high, and that’s thanks in large part to climate change. Rapidly intensifying hurricanes like Ian are so large and so powerful that even healthy insurance companies have a hard time dealing with them, and many resort to fraud and deception rather than pay out all their claims. A Washington Post investigation found that several companies cut payments below required levels, leaving victims short on cash when they needed it most. 

Even during quiet seasons, the mere threat of a hurricane will keep prices high. In preparation for hurricane season, insurance companies buy reinsurance policies that can help them survive the cost burden of big storms, and those policies are getting more expensive: In the months after Hurricane Ian, multinational reinsurers raised prices by as much as 50 percent

Local companies in Florida are passing those costs onto their customers, who open their bills each year to find that their premiums are ticking higher. To make matters worse, many insurance policies aren’t sufficient to recover from storms. In Cape Coral, which bore the brunt of Hurricane Ian’s winds last year, many victims have found their insurance payouts are so small they can’t afford to rebuild their homes.

Homeowners won’t see much relief any time soon, according to Palazola.

“In a middle-of-the-road scenario where the reforms work and there’s an average hurricane season, I could see a scenario where prices don’t go up dramatically from here,” he told Grist. “You’ve got an extreme scenario where we have a giant hurricane this year, and the reforms don’t work, you have more large insurers leaving, and the price becomes untenable, to the point where the average person feels it.”

Something similar is happening in other states that are vulnerable to climate disaster. In Louisiana, which has seen at least four major storms in the last few years, several private companies have collapsed since 2021’s Hurricane Ida, forcing more customers onto the state-backed plan. And multiple national insurers have fled California in recent weeks rather than try to make a profit selling policies in the state’s wildfire-prone mountains. There, too, homeowners have rushed to buy coverage from a state-backed insurer of last resort. In both of these states, prices have soared as natural disasters continue to strike.

If Hurricane Ian sent a big price shock through an unstable market, another storm this summer could deliver an even bigger blow, pushing more insurers away and forcing more Floridians into the Citizens program. Industry leaders and top government officials insist that the state’s market could survive such an event without total collapse, but another storm would raise prices even further for millions of homeowners across the state. Not only would reinsurers push costs higher to account for the storm risk, but the state government would likely have to charge a tax assessment to keep Citizens afloat.

In other words, no matter how well the legislature clamps down on fraud, the mounting toll of climate change is going to make Florida a less affordable place to live. Even on a sunny day, the status quo is expensive.

The Biden administration bets big on ‘climate smart’ agriculture

This story was originally published by Yale Environment 360 and is reproduced here as part of the Climate Desk collaboration.

A new kind of food may soon be arriving on grocery store shelves: climate smart. Under the Partnerships for Climate-Smart Commodities, a nascent U.S. Department of Agriculture (USDA) program, this amalgam of farming methods aims to keep the American agricultural juggernaut steaming ahead while slashing the sector’s immense greenhouse gas footprint.

This spring, the Biden administration began allocating $3.1 billion to hundreds of agriculture organizations, corporations, universities, and nonprofits for climate-smart projects. These entities will pass most of the money on to tens of thousands of farmers, ranchers, and forest owners, including growers who manage thousands of acres and underserved and disadvantaged farmers who often have much smaller operations. The first agreements have now been signed; the money is starting to flow.

The USDA estimates that the 141 funded projects will, collectively over the project’s five-year lifetime, eliminate or sequester the equivalent of 60 million metric tons of carbon dioxide emissions, on par with removing more than 2.4 million gas-powered cars from the road over the same period. They will achieve this by paying growers to adopt practices thought to either reduce greenhouse gas emissions or capture carbon dioxide from the air. These practices include reducing or eliminating tilling of soil, planting “cover crops” that grow during the off-season and are not harvested, improving how farmers use fertilizer and manure, and planting trees.

More importantly, the agency aims to catalyze new, premium markets for products such as climate-smart corn, soybeans, and beef, which it hopes will spur farmers to continue these practices far into the future. “People want to know that when they’re spending their dollar at the grocery store that they’re not hurting the environment; they want to be helpful,” Agriculture Secretary Tom Vilsack said last December when announcing projects that received funding. The emerging market for climate-friendly products, he added, represents “a transformational opportunity for U.S. agriculture.”

The idea has enthusiastic supporters. The market that Vilsack envisions “is potentially massive — much bigger than any federal program could be,” says Ben Thomas, senior policy director for agriculture at the Environmental Defense Fund. “And it’ll last as long as the conditions that create the market still exist.”

But the high-profile effort has also come under fire. Some researchers fear that the agency lacks a workable plan for measuring and verifying the impacts of the practices federal dollars will be paying for. Others say science has yet to prove that climate-smart practices truly reduce greenhouse gas emissions. “We don’t have that understanding yet for most climate-smart management practices,” says Kim Novick, an environmental scientist at Indiana University.

The program’s harshest critics assail it as a giveaway to rich corporations that will do little to rein in climate change — and might even exacerbate it. “This program is just pork for big polluters,” says University of Iowa economist Sylvia Secchi. “It’s a greenwashing scheme. It’s going to allow nothing to get done.”­

For decades, efforts to cut fossil fuel emissions have focused on power plants, factories, and automobiles, not farmland. “Agriculture has just not been at the table in a meaningful way,” says Thomas.

But it should be. For all of industrial farming’s success at feeding people and livestock and producing biofuel, the sector is also a major polluter, accounting for roughly 10 percent of U.S. greenhouse gas emissions and roughly a quarter of emissions globally. The main greenhouse gases emitted by U.S. agriculture today are nitrous oxide, which comes mainly from soil microbes that digest nitrogen fertilizer, and methane, burped by the nation’s roughly 92 million cows. Both warm the atmosphere far more, per molecule, than carbon dioxide.

Farmland itself was also once a major source of atmospheric carbon dioxide as farmers cleared carbon-rich forests and plowed up prairie soils, releasing carbon from trees and the ground. Now, climate-smart agriculture aims to recapture some of that carbon.

Unlike with organic farming, climate-smart farming has no list of allowed or prohibited practices. “There is no single definition of climate smart,” says Omanjana Goswami, an interdisciplinary scientist at the Union of Concerned Scientists. Instead, it comprises a mélange of practices that, studies show, can either reduce farms’ greenhouse gases emissions or increase the amount of carbon stored in their soils.

Funded projects are receiving up to $95 million over five years to help farmers take up these practices and to create monitoring and marketing programs that, it’s hoped, will keep farmers on the climate-smart track after the program ends. That all-carrot, no-stick strategy is intentional and necessary to reduce agriculture’s climate impact, says Robert Bonnie, under secretary for farm production and conservation at USDA and one of the program’s chief architects and champions.

“A voluntary, collaborative approach is the only approach that works here,” says Bonnie. “Regulation isn’t very good at asking people to adopt new practices.”

The department says the program will deliver benefits to underserved and disadvantaged farmers, a group that includes farmers of color, women, veterans, and small and beginning farmers who have, in the past, struggled to access USDA funding streams and have sometimes been intentionally excluded from them. Many of the projects whose signed agreements have been made public, for example, will direct at least 20 percent of funds to underserved farmers.

Champions of the program also note that expected benefits go beyond increasing carbon sequestration and reducing greenhouse gases from farm fields. By encouraging farmers to reduce tillage, plant cover crops, and take other measures, “we’re improving water quality; we’re reducing erosion,” says Adam Kiel, executive vice president of AgOutcomes, which is managing a $95 million climate-smart partnership led by the Iowa Soybean Association.

But as the climate-smart commodities program gets underway, many experts are warning that even its most-touted practices often fall far short. For example, some cover crop studies have found that the practice did not sequester significant amounts of carbon in soils, while other studies that did find gains also had gaps or methodological problems that diminished confidence in the results. And an analysis published in May in Nature Sustainability found that yield losses resulting from cover crops in the United States could erase as much as 70 percent of their climate benefits if farmers cut down trees elsewhere or plow up grasslands to compensate for those losses.

“I wouldn’t say we should pause everything, because there are some real benefits to cover cropping,” says David Lobell, a food security researcher at Stanford University and a coauthor of the Nature paper. “But I think we should be much more vigilant about maintaining productivity” as more farmers start using cover crops.

Other projects aim to reduce the greenhouse gas footprint of beef and dairy herds by more carefully managing how these animals graze pastures, so their manure can feed perennial grasses and other plants whose roots pull carbon deep into the soil. But grass-fed cows can also emit significantly more methane over their lifetimes than those that spend more of their lives in feedlots. Some projects plan to feed cows experimental additives that could reduce those methane emissions.

Measuring and modeling nitrous oxide emissions accurately is also notoriously difficult. And practices thought to reduce such emissions — like applying some fertilizer in the spring, just before planting, rather than applying all fertilizer in the fall — sometimes backfire. In fact, few long-term assessments of any climate-smart practices have been conducted on working farms, says Novick, making it hard to tailor practices to particular soil types, climates, and situations.

“It doesn’t appear that funding decisions from this program were necessarily made in a way that maximizes climate mitigation,” says Novick, who led a team that last fall authored a report on how science can inform nature-based climate solutions. “Ideally we would have first invested in the data tools necessary to understand when and where a practice is likely to succeed as a climate solution.”

There’s also the question of how to measure the program’s benefits. Funded groups are required to take measurements that will allow the USDA to assess the impacts of the practices farmers are implementing. But the agency is also relying heavily on a computer model that was designed to estimate greenhouse gases for planning large-scale projects and that cannot accurately quantify emissions and carbon capture from individual farms, notes Jon Sanderman, a soil scientist at the Woodwell Climate Research Center.

Bill Hohenstein, director of the USDA’s Office of Energy and Environmental Policy, acknowledges that the science behind climate-smart agriculture remains a work in progress. But he says it’s mature enough to take action. “We could wait a decade and probably understand these benefits better,” Hohenstein says. “But our view is that we would end up with generally the same recommendations.”

In addition to the technical challenges of measuring carbon and greenhouse gas changes, the Climate-Smart program will have to get farmers to stick with new practices after payments have ended. Officials say that payments to cover the startup costs for enrolled farmers are essential. “If this stuff was free, folks would already be doing it,” Bonnie says. But once they’ve bought equipment like seed drills for no-till planting and climbed the learning curve, he and Hohenstein say, reduced input costs, yield increases resulting from healthier soils, and premiums for climate-smart products will start to pay for themselves.

Many experts view such projections as overly optimistic. Hanna Poffenbarger, a soil scientist at the University of Kentucky, says it may take a decade for cover crop benefits, such as reduced need for fertilizer and increased soil organic matter, to translate into profits. That aligns with the experience of early adopters like Trey Hill, a farmer in Maryland who says that even after planting cover crops for more than 20 years, he’s still seeing yield losses in some of his corn fields and an unclear impact on his bottom line. “When you talk about improving soils,” he says, “we’re talking about a 10-year commitment before you would really even see anything significant.”

Details on the projects themselves have been slow to emerge. Though the projects receiving the bulk of the funding were announced last September, the USDA has so far shared fewer than a quarter of the signed agreements on its website. For the remaining projects, the department has published scant information. For example, a $61-million project led by the agribusiness giant Tyson to create and market “climate-smart beef” comes with only a two-sentence description that does not explain what practices will make beef climate smart. In response to an interview request, a Tyson representative linked to a blog post lacking substantive information on how the company’s claims will be verified.

The vagueness troubles observers like Goswami, of the Union of Concerned Scientists, who says that without clear standards, companies will define “climate smart” in different ways, potentially confusing customers. “If Tyson comes in and says farms and ranches who we’re buying cows from have implemented X amount of cover cropping, does that make their beef climate smart?” she asks.

Even people who received funding fear that the program could overwhelm or confuse farmers who are suddenly inundated with competing climate-smart offers. “In Iowa alone, there are 17 different climate-smart projects” that will be recruiting farmers, Kiel notes. At the same time, another branch of the USDA, the Natural Resources Conservation Service, has been tasked with disbursing nearly $20 billion injected by the Inflation Reduction Act into farm programs, including ones that pay farmers to grow cover crops or set aside land for conservation. Private-sector carbon markets are also courting farmers. And many of these initiatives require that farmers not take money from competing programs, to avoid double counting of climate benefits. “There’s going to be farmer confusion,” Kiel says. “It’s unfortunate, but at least there’s going to be lots of choices.”

Secchi, meanwhile, questions why some of the wealthiest corporations and individuals in industrial agriculture are receiving additional federal money. She would have instead liked to see the government insist that growers already receiving government subsidies through other programs do more to reduce their climate impact. “Why can’t we ask farmers who are getting crop insurance subsidies to plant cover crops at zero extra cost for the taxpayer?” Secchi asks. She’d also like to see more of the funds directed toward minority, Indigenous, and other disadvantaged farmers.

Bonnie, the USDA undersecretary, responds that catalyzing large-scale change requires working with companies big enough to reach thousands of growers farming millions of acres. Building a program that will create new markets rather than new regulations and policies, he adds, insulates climate-smart agriculture from future Congresses and administrations that may be less climate friendly.

One thing is certain: As the government looks to steer the ocean liner that is American farming in a direction that’s climate friendlier yet still highly profitable, a lot of eyes — both hopeful and skeptical — will be watching closely.

Smoke From Canada’s Wildfires Prompts U.S. Air Quality Alerts for 70 Million People in 32 States

Canada is currently experiencing its worst wildfire season ever, and on Monday smoke from the hundreds of blazes once again drifted across the border into the United States, prompting another round of air quality warnings.

The new bout of smoke and haze led to air quality alerts being issued for around 70 million people in 32 states and the District of Columbia, from Montana across to Vermont and all the way down into Northern Alabama, reported CNN and The New York Times. Cities affected included New York, Cleveland and Chicago.

“We are acutely aware that the recent weather events prominently impacting our City this summer are the direct result of the climate crisis,” said Chicago Mayor Brandon Johnson, as The New York Times reported.

Precautions like wearing masks and limiting time outside were recommended by officials. Wildfire smoke can irritate the nose, throat and eyes, and can lead to breathing issues. Exposure has also been associated with increased risks of heart attack, lung cancer, stroke and cognitive decline.

“The advice to limit strenuous activities is because when your respiratory rate is higher, you inhale more particulates,” said Yale Medicine’s Dr. Carrie Redlich on the Yale Medicine website. The tiny particles from the smoke “get everywhere through the bloodstream and trigger inflammatory pathways, which can exacerbate a number of underlying cardiac and respiratory conditions.”

Redlich said the best kind of mask to wear to protect yourself from the poor air quality that comes with wildfire smoke is an N95 or P100.

According to the Canadian Interagency Forest Fire Centre, 904 active fires were burning across Canada on Monday, with 587 out of control and 203 under control. In British Columbia (B.C.), officials reported 391 active fires, with 125 in Alberta and 107 in Québec, according to CBS News.

In some parts of the country, “light to moderate” smoke is forecast to hang around through mid-week, ABC News reported.

In the past week, two firefighters have lost their lives battling the epic blazes, prompting an outpouring of tributes and thanks for those on the front lines of the thus far untamable and relentless fires, reported The Guardian.

Of 19-year-old nursing student Devyn Gale, who had been helping to combat a fire near her hometown in B.C., the B.C. wildfire service said, “She was one of us. She was the heart of us,” as The Guardian reported.

“When they burn like this there’s no way to even put people in front of it to stop the fire, there’s no amount of resources on the ground or from the sky that’s going to be able to stop… these fires when they get the momentum,” said Matt Rau, an incident commander with the U.S.-based Southwest Area Incident Management Team, according to CNN in another report.

Some days, wildfire crews can work as long as 16 hours battling the unrelenting blazes.

Currently, fire crews from Mexico, New Zealand, the U.S. and, most recently, Australia are helping to fight the blazes alongside Canadian firefighters.

Heat Waves in Europe Threaten Olive Harvest for Second Consecutive Year

Olive harvests are expected to face a second challenging year in a row as heat waves threaten crops across Europe.

This year’s heat waves arrived a month earlier than the first heat waves of last year’s hot, dry season, according to Earth.org. The first heat wave arrived in late April, following a warmer- and drier-than-usual March. The winter was also unusually warm.

During the first heat wave of 2023, the trees were just beginning to flower, putting them in a vulnerable position.

“This happened as the olive trees were in bloom,” said Rafael Pico, director of Asoliva, the Spanish association of olive oil producers and exporters in Spain, as reported by Phys.org. “If there are no flowers, there’s no fruit. And if there’s no fruit, there’s no oil.”

Spain, the largest olive oil producer in Europe, has had its annual supply decline by half because of the heat and drought. Last year, heat waves caused the country’s olive oil production to decline from 1.48 million metric tons in 2021 to 2022 to just 660,000 metric tons from 2022 to 2023. Experts are predicting olive oil supply to reach 850,000 metric tons this year, still far below average, but continuing heat waves could impact the harvest.

“In Spain we already know it is going to be another bad year, but no one has got to grips with the what’s currently happening. The record temperatures are not going to help the situation,” Walter Zanre, the chief executive of the UK branch of Filippo Berio, the largest olive oil producer globally, told The Guardian. “I can’t share how much anxiety this is causing us. Last year, Spain came into crop with a bit of carry-over [from the year before], which negated the shortfall somewhat. This year the barrels are dry. Even if Spain produces the predicted 850,000 tonnes, the price situation is worse.”

Spain isn’t alone. Other major olive oil-producing countries, such as Italy and Portugal, have experienced smaller yields because of the harsh conditions.

Since June 2022, olive oil prices have surged in response to the poor olive harvests, as the crop has been affected by the extreme heat. Olive oil prices have hit over $6,000 per metric ton, the highest price this product has been since 1997, Weather.com reported.

As The Guardian reported, consumers may expect to see shortages of olive oil in the fall, as last year’s supply is expected to run out in September, and the new supply for 2023 isn’t expected to be ready until November.

Many crops are facing shortages amid the climate crisis. The current heat waves in Europe are also threatening vineyards, even putting types of grapes that have long been known to survive in extreme conditions at risk. Maturing tomatoes in Italy are at risk from blistering in the extreme temperatures, and these crops were already impacted by severe floods earlier this year.
