Pesticides once appeared to be a clear target for Robert F. Kennedy Jr.’s desire to “make America healthy again.” Before becoming the health secretary, he described Monsanto, the maker of the glyphosate-based herbicide Roundup, as “enemy of every admirable American value,” and vowed to “ban the worst agricultural chemicals already banned in other countries.” Since he came to power, many of Kennedy’s fans have waited eagerly for him to do just that.

Derrick Hiebert had planned to stick it out at FEMA. He was an assistant administrator working on hazard mitigation—he specialized in getting communities prepared for disasters—and like many emergency-management experts I’ve spoken with, he thinks that the American approach to administering disasters needed an overhaul, even a radical one. The systems had gotten “clunky over time,” he said. Something needed to change. So Hiebert was open to seeing how President Donald Trump might change it.

If you are like me, you brush your teeth—too vigorously, I’m told—with a plastic rack of plastic bristles. You use your plastic brush to lather a paste pushed from a plastic tube. When you have a cavity, you go to a dentist who might fill the hole with a plastic composite then sand it flush right there in your mouth. Say you grind your teeth at night.

Before the waters of Texas’s Guadalupe River rose more than 33 feet over the course of five hours, the National Weather Service sent out a series of alerts. The first one that included Kerr County, where most of the fatalities would ultimately take place, warned of “considerable” flood threat and went out just after 1 a.m. on July 4. It triggered push alerts on people’s phones. It set off alarms on any weather radio tuned to the National Oceanic and Atmospheric Administration’s frequency.

At 4 p.m. ET yesterday, Andrew Hazelton got a form email telling him his work as a hurricane modeler at the federal government would be officially over at 5 p.m. that day. In his five months as a federal employee, his job was to help improve the models that serve as the basis for the National Hurricane Center’s forecasts.

In Wisconsin, where late last year Donald Trump said at a campaign stop, “I’m an environmentalist … I want clean air and clean water—really clean water,” many people want that too. Like Americans across the country, many Wisconsinites have in recent years come to understand that they have been drinking water contaminated by highly toxic “forever chemicals,” compounds known as PFAS, for decades.

When the tanker ships come toward the tiny town of Cameron, Louisiana, Travis Dardar, a shrimp fisherman, can hear their wake coming before he sees it, he told me earlier this year. They’re there to pick up natural gas that’s been supercooled to a liquid state at a sprawling export facility, built atop hundreds of wetland acres in the past few years, and to transport that gas to ports in Europe and Asia.

This year is set to break the record for the hottest year ever recorded. It was a banner year for climate devastation: Southern Africa and South America suffered under severe droughts; dangerous heat bore down on large parts of Asia, Europe, and Central America; and an alarming number of wildfires consumed more than 1 million hectares in Brazil. Hurricanes, intensified by abnormally hot seawater, pummeled the Caribbean and the American Southeast, and floods deluged parts of Africa and Europe.

The problem that the United Nations’ annual climate conference was meant to solve this year was, in one way, straightforward. To have any hope of meeting their commitments to holding global warming at bay, developing countries need at least $1 trillion a year in outside funding, according to economists’ assessments. Failure to meet those commitments will result in more chaotic climate outcomes globally. Everyone agrees on this.

In Mexico, the conditions that have contributed to the largest sustained movement of humans across any border in the world will get only more common. This spring, at the start of the corn-growing season, 76 percent of Mexico was in drought, and the country was sweltering under a deadly heat dome. Finally, after too many months, summer rains started to refill reservoirs. But years and droughts like this promise to become more intense: Mexico is slated to warm 1 to 3 degrees Celsius by 2060.

Last month, an energy think tank released some rare good news for the climate: The world is on track to install 29 percent more solar capacity this year than it did the year before, according to a report from Ember. “In a single year, in a single technology, we’re providing as much new electricity as the entirety of global growth the year before,” Kingsmill Bond, a senior energy strategist at RMI, a clean-energy nonprofit, told me.

The United States is trapped in a cycle of disasters bigger than the ones our systems were built for. Before Hurricane Helene made landfall late last month, FEMA was already running short on funds; now, Alejandro Mayorkas, the Homeland Security secretary, told reporters on Wednesday, if another hurricane hits, it will run out altogether.

A placenta is, by definition, new tissue: It grows from scratch over nine months of pregnancy. So when a team of researchers found microplastics in every human placenta they sampled, they were a little bit shocked, Matthew Campen, a professor at the University of New Mexico and a researcher on the team, told me. But in hindsight, he thinks perhaps they shouldn’t have been. Microplastics are in the air we breathe, the water we drink, the rain and snow falling from the sky, the food we eat.

Tonight’s presidential debate was held while wildfires rage in Nevada, Southern California, Oregon, and Idaho. Louisiana is bracing for a possible hurricane landfall. After a year of floods and storms across the country, more than 10 percent of Americans no longer have home insurance, as climate risk sends the insurance industry fleeing vulnerable places. Record heat waves have strained infrastructure and killed hundreds of Americans.

A basic fact of thermodynamics is coming to haunt every foot of train track in the United States. Heat makes steel expand, moving its molecules farther apart, and as hot days become hotter and more frequent, rail lines are at risk of warping and buckling more often.
Any fix must deal with this fundamental truth of physics. Railroads can slow their trains down, which avoids adding more heat.

Monday was likely the hottest day on Earth since modern recordkeeping began. On that day, the planet was 17.16 degrees Celsius, or 62.89 degrees Fahrenheit, on average, according to the European climate service Copernicus, narrowly beating out the previous record, set just the day before, by about 0.1 degrees. That news, like previous records of its kind, was quickly characterized as the hottest day in millennia—since the peak of the last interglacial period, about 125,000 years ago.

Last July, I was living in Montreal when an emergency push alert from Canada’s environmental agency popped up on my phone, accompanied by a loud alarm. It had been raining ferociously that afternoon, and the wind was picking up. The alert warned of something worse—a marine tornado, which “are often wrapped in rain and may not be visible”—and ordered, “Take cover immediately if threatening weather approaches.”
I looked outside. The wind was howling louder now, and the sky was a strange gray.

In a 6–3 ruling today, the Supreme Court essentially threw a stick of dynamite at a giant, 40-year-old legal levee. The decision overruled what is known as the Chevron doctrine, a precedent that governed how American laws were administered. In doing so, it likely unleashed a river of litigation, much of which could erode away the country’s climate and environmental ambitions.

It’s troublingly hot in June, which means the United States is entering the heat-death zone for workers again. We’ve been here before. In San Antonio, on a blisteringly hot June day in 2022, Gabriel Infante, a 24-year-old construction worker, died in his first week on the job, after he entered a state of delirium while laying fiber-optic cable; medics measured his temperature at 109.8 degrees Fahrenheit. That same month, Esteban Chavez Jr.

Summertime in North America is becoming smoke season. Last summer, when a haze from catastrophic Canadian wildfires hung over the continent—turning Montreal, where I lived at the time, an unearthly gray and my home city of New York a putrid orange—plenty of people seemed untroubled by this reality. Relatively few people wore masks; infamously, an outdoor yoga class continued on a skyscraper terrace in Manhattan.

Cordelia Saunders remembers 2021, the year she and her husband, Nathan, found out that they’d likely been drinking tainted water for more than 30 years. A neighbor’s 20 peach trees had finally matured that summer, and perfect-looking peaches hung from their branches. Cordelia watched the fruit drop to the ground and rot: Her neighbor didn’t dare eat it.

The Biden administration earlier today issued a major new rule intended to spur the country’s electric-vehicle industry and slash future sales of new gas-powered cars. The rule is not a ban on gas cars, nor does it mandate electric-vehicle sales. It is a new emissions standard, requiring automakers to cut the average carbon emission of their fleets by nearly 50 percent by 2032.

The gallon pot of white petunias I held on an otherwise ordinary subway train, on an otherwise ordinary Thursday in March, would have looked to anyone else like an ordinary houseplant. But I knew better. An hour before, Karen Sarkisyan, one of the plant scientists responsible for this petunia’s existence, had dropped it off at my office. He warned me that my petunia had spent a while in transit, and might not immediately put on a show. Still, I’d rushed the petunia into a windowless room.

It feels like a sin against the sanctitude of being alive to put a dollar value on one year of a human life. A year spent living instead of dead is obviously priceless, beyond the measure of something so unprofound as money. But it gets a price tag in the world of economic models. Different agencies and organizations use different estimates—no one can seem to agree on the precise going rate. But according to the Environmental Protection Agency, a statistical lifetime is valued at about $11.

If Donald Trump wins a second term, and his administration realizes conservative advocacy groups’ plans to dismantle environmental protections and drill, baby, drill, the United States is in for four years of relentless carbon pollution. In other words, another Trump presidency all but guarantees a complete abnegation of the country’s climate duties from 2025 to 2029.

All of a sudden, the U.S. has become the biggest liquid-natural-gas exporter in the world. Supplied by a souped-up hydraulic-fracturing industry, and spurred by Russia’s war on Ukraine, which has hampered European gas access, LNG export terminals are being built on a monumental scale throughout the U.S. Gulf Coast, in places so beset by climate disasters that homes there are now deemed uninsurable.

In a 1998 Atlantic cover story, William H. Calvin offered perhaps the best oceanography lesson to appear in a major national magazine.

From a climate perspective, 2024 is beginning in uncharted territory. Temperatures last year broke records not by small intervals but by big leaps; 2023 was the hottest year ever recorded, and each month in the second half of the year was the hottest—the hottest June, the hottest July, all the way through to December. July was in fact the hottest month in recorded history. Already, experts predict that 2024 is likely to be even hotter.

For as long as the world’s diplomats have gathered to talk about slowing the march of climate change, the one institution pointedly missing from the agenda has been the military. This has been by design: At the behest of the U.S., reporting military emissions was largely exempted from the 1997 Kyoto Protocol, the document that set binding emissions targets for nations that signed. The 2015 Paris Agreement overturned the old exemption but still did not require reporting of military emissions.

In January 1995, when The Atlantic published “In Praise of Snow,” Cullen Murphy’s opus to frozen precipitation, snow was still a mysterious substance, coming and going enigmatically, confounding forecasters’ attempts to make long-term predictions. Climate change registered to snow hydrologists as a future problem, but for the most part their job remained squarely hydrology: working out the ticktock of a highly variable yet presumably coherent water cycle.
