I won’t sugar coat this: The election of Donald Trump to a second term with a likely governing trifecta has dealt a devastating blow to U.S. efforts to cut climate-warming pollution.
I’ve spent the past four years analyzing the progress made under the Biden-Harris Administration as leader of the REPEAT Project, which uses energy systems models to rapidly assess the impact of federal energy and climate policies. In that time, the passage of landmark legislation — the Inflation Reduction Act and Bipartisan Infrastructure Law — and finalization of key federal regulations on greenhouse gas emissions from power plants, cars and trucks, and oil and gas supply chains put the U.S. on track to more than double its pace of decarbonization and avoid about 6 billion tons of cumulative emissions through 2035. Though even that progress was not enough: Recent policies would do only about half the work required to bend U.S. emissions onto a net-zero pathway by 2035.
A President Harris would have fought to protect and build on the efforts of the past four years. Now that opportunity is lost. One notable climate scientist even declared a second Trump term “game over for the climate.”
With Trump once again ascendant and seemingly committed to dismantling the historic climate progress made by the United States over the past four years, one can be forgiven for feeling anguish about the opportunities we’ve lost, rage about the very real suffering that will result from further delay, or deep despair about the darker days ahead.
But only for a moment. Because the fight to defend that progress begins today, and there is no time to lose.
In 1992, the nations of the world established the United Nations Framework Convention on Climate Change and pledged to "prevent dangerous human induced interference with the climate system." As the parties to the UNFCCC gather once again in Azerbaijan this December, one thing should be clear to all: We have failed in that task. This year is virtually certain to be the warmest on record and the first to breach 1.5 degrees Celsius above pre-industrial temperatures. Wildfires and droughts, hurricanes and floods now seem to strike with alarming frequency and terrible ferocity.
Yet the best science tells us that climate change is not like an asteroid hurtling towards earth, an all-or-nothing battle for survival. Rather, scientists tell us that every billion tons of CO2 and every 10th of a degree of warming we prevent will save lives, prevent suffering, and avoid countless damage.
The fight cannot be surrendered, and the project of building a world where the lives and aspirations of 8-going-on-10 billion people can be powered by clean, abundant energy remains essential.
Indeed, I have been in this fight long enough to have experienced several gutting defeats before — and to have witnessed real, transformative progress.
When I began my career nearly two decades ago, a good onshore wind project cost $100 to $200 per megawatt-hour, two to five times the average cost of fossil power. Germany had just launched a subsidy program paying a lavish €400 to €500 per megawatt-hour for solar photovoltaics. And it would be several years still before the first Tesla Roadster would even hit the streets.
Today, either solar or wind power is the cheapest way to generate new electricity almost everywhere in the world, and the International Energy Agency expects solar to overtake nuclear, wind, hydro, gas, and, finally, coal, to become the largest source of electricity in the world by 2033. Here in the U.S., clean electricity and battery storage constitute virtually all of the more than 2.5 terawatts of projects requesting interconnection to our grids. Likewise, electric vehicles (whether two-, three-, or four-wheeled) are now the cheapest and fastest growing mobility solution for those in emerging economies and the rich world alike. One in five cars and trucks sold globally are now electric — in China, that figure is nearing 50%.
Annual U.S. emissions are more than a billion metric tons (or 16%) lower than their peak in 2007, even as the economy is 40% larger. The European Union has cut emissions by 37% from their peak, and by 8% in 2023 alone. Even China, the world’s top polluter, may have seen its emissions peak in 2023 — seven years ahead of schedule.
In sum, the trajectory of global emissions has been wrestled down from inexorable rise to plateau and impending peak. That may not be enough to prevent dangerous climate change, but it is sufficient to transform the outlook from a bleak world of around 4 degrees of warming and put a much more manageable world of 2 degrees within reach.
The truth is that Donald Trump can only slow, not stop the clean energy transition. The U.S. is only responsible for about a 10th of global emissions, and China, not America, is now the world’s largest market (by far) for cars and trucks, electricity, and industrial commodities like steel and cement. Trump cannot wind back the clock on technological innovation or dampen the appetite for EVs and clean energy in the rest of the world. Emerging climate technologies like decarbonized steel, cement and industrial heat can take root elsewhere, even if they face dimmer prospects in America. And a bipartisan consensus to advance technologies like geothermal, nuclear, and carbon capture in the U.S. remains.
While executive actions can be easily repealed, the legislative achievements of the past four years lower energy prices for American consumers and businesses, have sparked a long-promised American manufacturing renaissance, and direct substantial investment and job creation to Republican-represented districts and states. Texas, that paragon of conservatism, is now the undisputed king of clean energy. Factories producing batteries, EVs and solar panels are sprouting across Georgia, the Carolinas, Kentucky, Indiana, Michigan, and beyond. Clean energy is now big business, and influential companies stand to lose billions if the Inflation Reduction Act is repealed. With Republicans securing razor-thin legislative majorities, these laws could thus prove surprisingly durable.
In times of struggle and defeat, those brave champions of civil rights would remind themselves that, though long, the arc of history bends towards justice. Today, it remains our collective task to continue to bend the arc of global emissions towards net zero.
Vice President Harris began her historic campaign by declaring, “When we fight, we win!” That isn’t always the case, but we can say with absolute certainty that if we give up the fight, we are guaranteed defeat.
There is no “game over” in the fight against climate change. The next battle begins today.

Imagine for a moment that you’re an aerial firefighter pilot. You have one of the most dangerous jobs in the country, and now you’ve been called in to fight the devastating fires burning in Los Angeles County’s famously tricky, hilly terrain. You’re working long hours — not as long as your colleagues on the ground due to flight time limitations, but the maximum scheduling allows — not to mention the added external pressures you’re also facing. Even the incoming president recently wondered aloud why the fires aren’t under control yet and insinuated that it’s your and your colleagues’ fault.
You’re on a sortie, getting ready for a particularly white-knuckle drop at a low altitude in poor visibility conditions when an object catches your eye outside the cockpit window: an authorized drone dangerously close to your wing.
Aerial firefighters don’t have to imagine this terrifying scenario; they’ve lived it. Last week, a drone punched a hole in the wing of a Québécois “super soaker” plane that had traveled down from Canada to fight the fires, grounding Palisades firefighting operations for an agonizing half-hour. Thirty minutes might not seem like much, but it is precious time lost when the Santa Ana winds have already curtailed aerial operations.
“I am shocked by what happened in Los Angeles with the drone,” Anna Lau, a forestry communication coordinator with the Montana Department of Natural Resources and Conservation, told me. The Montana DNRC has also had to contend with unauthorized drones grounding its firefighting planes. “We’re following what’s going on very closely, and it’s shocking to us,” Lau went on. Leaving the skies clear so that firefighters can get on with their work “just seems like a no-brainer, especially when people are actively trying to tackle the situation at hand and fighting to save homes, property, and lives.”

Although the super soaker collision was by far the most egregious case, according to authorities there have been at least 40 “incidents involving drones” in the airspace around L.A. since the fires started. (Notably, the Federal Aviation Administration has not granted any waivers for the air space around Palisades, meaning any drone images you see of the region, including on the news, were “probably shot illegally,” Intelligencer reports.) So far, law enforcement has arrested three people connected to drones flying near the L.A. fires, and the FBI is seeking information regarding the super soaker collision.
Such a problem is hardly isolated to these fires, though. The Forest Service reports that drones led to the suspension of or interfered with at least 172 fire responses between 2015 and 2020. Some people, including Mike Fraietta, an FAA-certified drone pilot and the founder of the drone-detection company Gargoyle Systems, believe the true number of interferences is much higher — closer to 400.
Law enforcement likes to say that unauthorized drone use falls into three buckets — clueless, criminal, or careless — and Fraietta was inclined to believe that it’s mostly the former in L.A. Hobbyists and other casual drone operators “don’t know the regulations or that this is a danger,” he said. “There’s a lot of ignorance.” To raise awareness, he suggested law enforcement and the media highlight the steep penalties for flying drones in wildfire no-fly zones, which is punishable by up to 12 months in prison or a fine of $75,000.
“What we’re seeing, particularly in California, is TikTok and Instagram influencers trying to get a shot and get likes,” Fraietta conjectured. In the case of the drone that hit the super soaker, it “might have been a case of citizen journalism, like, Well, I have the ability to get this shot and share what’s going on.”
Emergency management teams are waking up, too. Many technologies are on the horizon for drone detection, identification, and deflection, including Wi-Fi jamming, which was used to ground climate activists’ drones at Heathrow Airport in 2019. Jamming is less practical in an emergency situation like the one in L.A., though, where lives could be at stake if people can’t communicate.
Still, the fact of the matter is that firefighters waste precious time dealing with drones when there are far more pressing issues that need their attention. Lau, in Montana, described how even just a 12-minute interruption to firefighting efforts can put a community at risk. “The biggest public awareness message we put out is, ‘If you fly, we can’t,’” she said.
Fraietta, though, noted that drone technology could be used positively in the future, including on wildfire detection and monitoring, prescribed burns, and communicating with firefighters or victims on the ground.
“We don’t want to see this turn into the FAA saying, ‘Hey everyone, no more drones in the United States because of this incident,’” Fraietta said. “You don’t shut down I-95 because a few people are running drugs up and down it, right? Drones are going to be super beneficial to the country long term.”
But critically, in the case of a wildfire, such tools belong in the right hands — not the hands of your neighbor who got a DJI Mini 3 for Christmas. “Their one shot isn’t worth it,” Lau said.
Plus 3 more outstanding questions about this ongoing emergency.
As Los Angeles continued to battle multiple big blazes ripping through some of the most beloved (and expensive) areas of the city on Friday, a question lingered in the background: What caused the fires in the first place?
Though fires are less common in California during this time of the year, they aren’t unheard of. In early December 2017, power lines sparked the Thomas Fire near Ventura, California, which burned through to mid-January. At the time it was the largest fire in the state since at least the 1930s. Now it’s the ninth-largest. Although that fire was in a more rural area, it ignited for some of the same reasons we’re seeing fires this week.
Read on for everything we know so far about how the fires started.
Six major fires started during the Santa Ana wind event last week:
Officials are investigating the cause of the fires and have not made any public statements yet. Early eyewitness accounts suggest that the Eaton Fire may have started at the base of a transmission tower owned by Southern California Edison. So far, the company has maintained that an analysis of its equipment showed “no interruptions or electrical or operational anomalies until more than one hour after the reported start time of the fire.” A Washington Post investigation found that the Palisades Fire could have risen from the remnants of a fire that burned on New Year’s Eve and reignited.
On Thursday morning, Edward Nordskog, a retired fire investigator from the Los Angeles Sheriff’s Department, told me it was unlikely they had even begun looking into the root of the biggest and most destructive of the fires in the Pacific Palisades. “They don't start an investigation until it's safe to go into the area where the fire started, and it just hasn't been safe until probably today,” he said.
It can take years to determine the cause of a fire. Investigators did not pinpoint the cause of the Thomas Fire until March 2019, more than two years after it started.
But Nordskog doesn’t think it will take very long this time. It’s easier to narrow down the possibilities for an urban fire because there are typically both witnesses and surveillance footage, he told me. He said the most common causes of wildfires in Los Angeles are power lines and those started by unhoused people. They can also be caused by sparks from vehicles or equipment.
At more than 40,000 acres burned total, these fires are unlikely to make the charts for the largest in California history. But because they are burning in urban, densely populated, and expensive areas, they could be some of the most devastating. With an estimated 9,000 structures damaged as of Friday morning, the Eaton and Palisades fires are likely to make the list for most destructive wildfire events in the state.
And they will certainly be at the top for costliest. The Palisades Fire has already been declared a likely contender for the most expensive wildfire in U.S. history. It has destroyed more than 5,000 structures in some of the most expensive zip codes in the country. Between that and the Eaton Fire, Accuweather estimates the damages could reach $57 billion.
While we don’t know the root causes of the ignitions, several factors came together to create perfect fire conditions in Southern California this week.
First, there’s the Santa Ana winds, an annual phenomenon in Southern California, when very dry, high-pressure air gets trapped in the Great Basin and begins escaping westward through mountain passes to lower-pressure areas along the coast. Most of the time, the wind in Los Angeles blows eastward from the ocean, but during a Santa Ana event, it changes direction, picking up speed as it rushes toward the sea.
Jon Keeley, a research scientist with the US Geological Survey and an adjunct professor at the University of California, Los Angeles told me that Santa Ana winds typically blow at maybe 30 to 40 miles per hour, while the winds this week hit upwards of 60 to 70 miles per hour. “More severe than is normal, but not unique,” he said. “We had similar severe winds in 2017 with the Thomas Fire.”
Second, Southern California is currently in the midst of extreme drought. Winter is typically a rainier season, but Los Angeles has seen less than half an inch of rain since July. That means that all the shrubland vegetation in the area is bone-dry. Again, Keeley said, this was not usual, but not unique. Some years are drier than others.
These fires were also not a question of fuel management, Keeley told me. “The fuels are not really the issue in these big fires. It's the extreme winds,” he said. “You can do prescription burning in chaparral and have essentially no impact on Santa Ana wind-driven fires.” As far as he can tell, based on information from CalFire, the Eaton Fire started on an urban street.
While it’s likely that climate change played a role in amplifying the drought, it’s hard to say how big a factor it was. Patrick Brown, a climate scientist at the Breakthrough Institute and adjunct professor at Johns Hopkins University, published a long post on X outlining the factors contributing to the fires, including a chart of historic rainfall during the winter in Los Angeles that shows oscillations between wet and dry years over the past eight decades.
But climate change is expected to make dry years drier and wet years wetter, creating a “hydroclimate whiplash,” as Daniel Swain, a pre-eminent expert on climate change and weather in California puts it. In a thread on Bluesky, Swain wrote that “in 2024, Southern California experienced an exceptional episode of wet-to-dry hydroclimate whiplash.” Last year’s rainy winter fostered abundant plant growth, and the proceeding dryness primed the vegetation for fire.

On tough questioning from the Senate, LA’s fires, and EV leases
Current conditions: Odd weather has caused broccoli and cauliflower plants to come up far too early in the UK • Another blast of Arctic air is headed for the Midwest • An air quality alert has been issued in Los Angeles due to windblown dust and ash.
Firefighters in Los Angeles are scrambling to make progress against the ongoing wildfires there before dangerous winds return. The Palisades and Eaton fires have now been burning for almost a week, charring nearly 40,000 acres, damaging more than 12,000 structures, and leaving at least 24 people dead. They are 13% and 27% contained, respectively. Residents who lost their homes are desperately trying to find new properties to rent or buy in a tight market, with reports of intense bidding wars as landlords hike rents. The economic toll of this disaster is estimated to be between $135 billion and $150 billion. Red flag warnings are in effect today, with critical fire conditions and extreme wind gusts forecast through Wednesday.

A few updates on the incoming administration: President-elect Donald Trump tapped Ed Russo to run an advisory environmental task force. Trump said Russo will oversee “initiatives to create great jobs and protect our natural resources, by following my policy of CLEAN AIR and CLEAN WATER. Together, we will achieve American Energy DOMINANCE, rebuild our Economy, and DRILL, BABY, DRILL.” Russo is a longtime Trump loyalist who served as an environmental consultant to the Trump Organization and wrote a book titled “Donald J. Trump: An Environmental Hero”.
Trump also announced his deputies for some key environmental and energy Cabinet positions over the weekend, including:
More than a dozen of Trump’s Cabinet nominees face Senate confirmation hearings this week. Doug Burgum, who is up for interior secretary, has a hearing before the Committee on Energy and Natural Resources tomorrow. Energy secretary nominee Chris Wright has one on Wednesday. EPA nominee Lee Zeldin has one with the Environment and Public Works Committee on Thursday.
Affordable EV leases are “the car market’s hottest deal,” according toThe Wall Street Journal. Car companies are changing the way they pitch EVs to buyers, offering short-term leases with low monthly payments. These deals are attractive to first-time EV shoppers who are still a little bit hesitant to commit, as well as people on a tighter budget. Roughly 45% of EV transactions at the end of 2024 were leases, much higher than the auto industry as a whole. And a provision in the Inflation Reduction Act means leased cars can more easily qualify for the government’s $7,500 EV tax credit. “The proliferation of lease deals has made EVs more accessible to buyers who couldn’t afford their higher sticker prices,” the Journal said. “For the automakers, it is helping get more EVs into customers’ hands after a choppy start for their electric-car operations.”
Wind power could overtake coal in Europe for electricity generation for the first time this year, according to the energy think tank Ember. At the end of 2024, wind power was closing in on coal, coming in at just 4% below the fossil fuel in power generation as the continent’s coal plants close. “That output gap could easily be made up over the course of 2025 by an increase in regional wind generation capacity or by higher average wind speeds at turbine level, or by some combination of both,” Reutersreported. Last year wind power accounted for 20% of electricity consumed in the EU, and the goal is to get that up to 50% by 2050. But as Electreknoted, the same problems plaguing projects in the U.S. – permitting delays and connection bottlenecks – are slowing things down. The EU accounts for 4.6% of global power sector emissions.
The World Health Organization’s European Centre for Environment and Health has issued a callout for “examples of interventions to protect and promote mental health in the face of climate change.” The group wants to take stock of these interventions so that it can identify gaps in mental health care and share some best practices. The callout is aimed at Europe only, but it is indicative of a growing awareness of how the worsening climate crisis is taking a toll on mental health worldwide.
“There’s a lot of finger-pointing going around, and I would just try to emphasize that this is a really complex problem. We have lots of different responsible parties. To me, what has happened requires more of a rethink than a blame game.” –Faith Kearns, a water and wildfire researcher at Arizona State University, speaking to Heatmap about the spread of misinformation around the LA fires
