Five years from the emergence of the disease, the world — and the climate — is still grappling with its effects.
Five years ago this month, the novel coronavirus that would eventually become known as Covid-19 began to spread in Wuhan, China, kicking off a sequence of events that quite literally changed the world as we know it, the global climate not excepted.
The most dramatic effect of Covid on climate change wasn’t the 8% drop in annual greenhouse gas emissions caused by lockdowns and border closures in 2020, however. It wasn’t the crash in oil prices, which briefly went negative in April 2020. It wasn’t the delay of COP26 and of the United Nations Intergovernmental Panel on Climate Change’s Sixth Assessment Report. And it wasn’t, sadly, a legacy of green stimulus measures (some good efforts notwithstanding).
Rather, it was in the way the world’s governments (especially the largest and most powerful) responded to the virus, which undermined the very idea of multilateralism, climate action included. This took place along three main vectors: inertia on global financial rules, even as long-acknowledged failings turned catastrophic; a renaissance in industrial policy that may prove transformative for domestic fiscal policy; and, at the intersection of both, deterioration of what we might call geopolitics or “global solidarity.”
Evidence of this phenomenon can be found in nearly every aspect of the global order. The World Bank in October pointed to Covid as chief among a “polycrisis” of “multiple and interconnected crises occurring simultaneously, where their interactions amplify the overall impact.” Development gains have almost slowed to a halt. Extreme poverty has increased overall in low-income countries since 2014, after decades of improvement, according to the World Bank’s analysis.
None of this, however, was an inevitable effect of Covid. Poor countries got poorer, for the most part, because of norms and hard rules in global finance that they have little control over — what a group of researchers last year termed “financial subordination.”
To understand why, a brief history: Developing countries during the 2010s were seeking new avenues of finance as traditional sources like multilateral development bank loans, official development assistance, and commercial bank loans waned. Many turned to the U.S. dollar sovereign bond markets, and also to China; a few countries also turned to commodity traders like Glencore and Trafigura, taking on opaque debts to be repaid with their own oil and other commodities.
When the pandemic response shut down many kinds of economic activity in 2020, what World Bank researchers called a “fourth wave” of debt followed. After a continuous series of debt surges from 1970 to 1989, 1990 to 2001, and 2002 to 2009, global debt markets had been relatively stable for the preceding decade. What was different about this fourth wave was that it was largely in developing countries.
With Covid, the fourth wave turned into a tsunami. Countries everywhere were paralysed by the pandemic, but the poorest ones lost critical revenue from tourism, remittances, and some exports. On top of that, they suffered the same lockdowns and illness that depressed local economic activity and drained government budgets in many countries. Unlike rich countries, developing countries had limited ability to dip into reserves or raise money from the bond markets to keep their citizens safe and tide over those who lost work.
Wealthy countries and lenders did little to ameliorate this stress. A “Debt Servicing Suspension Initiative” facilitated by the G20 provided some relief for 46 countries; China participated, too, granting deferrals to some of its debtor countries. But private bondholders (who were earning returns as high as 9%) and multilateral banks did not. The debts still had to be paid, and by 2023, aggregate net capital flows were negativefor developing countries — that is, more money flowed from poorer countries to richer ones than the other way around.
Numerous governments defaulted on their debts in the wake of Covid, including Ghana, Sri Lanka, Zambia, Ethiopia, and Suriname. But perhaps just as bad, many, many more countries continued to pay their debts by slashing their health and social welfare budgets just as they were needed most. Low- and middle-income countries spent more on debt servicing in 2022 than they spent on health in 2020, during the height of the pandemic.
Tensions between the U.S. and China, meanwhile, became even more overt around Covid, helped in part by accusations and recriminations over the source of the disease. The two great powers were themselves deeply changed. China emerged from its Covid Zero measures with public discontent at a nearly unprecedented pitch and its engines of economic growth — domestic infrastructure and residential property — faltering as vast local government debts became unmanageable. The country’s central government renewed its focus on an export-led growth model, but this time instead of cheap, low-tech consumer goods, it was semiconductors, solar panels, and electric vehicles.
It quickly became clear that the Biden administration would not be much less hawkish towards China than Trump’s was. It largely focused inwards, on tackling the disenfranchisement of formerly solid Democratic working class constituencies that Trump had exploited and Covid deepened. These were largely seen as an outcome of untrammelled free trade — especially with China. But Covid lockdowns and the rush to regain normalcy in the re-opening choked complex supply chains and logistics networks, driving up prices around the world and helping to spark a global inflation crisis that has yet to meaningfully abate in many parts of the world.
When Russia invaded Ukraine, energy prices shot up, particularly in those countries reliant on imported oil and natural gas. This shook the global fossil energy economy. Exports of liquified natural gas by the United States to Europe skyrocketed, as European countries desperately sought alternatives to Russian piped gas. Those same desperate Europeans also bought LNG shipments that had been bound for countries like Bangladesh and Pakistan, outbidding the poorer countries which then endured blackouts and further hits to their financial reserves as they struggled to match the new EU price.
Global energy price rises compounded the Covid supply-chain pressures and monetary policymakers decided hiking interest rates was unavoidable. While Russian troops tried to capture Kyiv in March of 2022, the U.S. Federal Reserve — perhaps the most powerful U.S. entity for the rest of the world — began hiking interest rates, taking them from just a quarter of a percent before the invasion to more than 5% by mid-2023. This strengthened the U.S. dollar, heaping more pressure on developing countries trying to pay dollar-denominated debts. Meanwhile, in rich and poor countries alike, the jump in living costs has helped drive backlashes against incumbents, and a surge in far-right populism.
Perhaps years ago, if we’d known that we’d see a spike in temperatures, droughts, and storms alongside a flood of cheap solar panels and EVs, technological breakthroughs in batteries, and a renewed interest in industrial policy, it might have seemed that more urgent climate action was assured. Instead, divisions have worsened. The agreement text from this year’s United Nations climate conference is actually slightly watered down from the last year’s statement on fossil fuel phaseout. A special conference on biodiversity Cali, Colombia, finished last month only when delegates had to catch flights home, and a desertification conference hosted by Saudi Arabia finished this month with no group statement.
Rachel Kyte, the UK special envoy for climate change, told an event hosted by the Overseas Development Institute think tank that even as it approached its 10-year anniversary, the 2015 Paris Agreement was more fragile than it had ever been. Countries like the UK, she said, had been inflicting “paper cuts” on developing countries for so long that the ill will was becoming impossible to wave away.
“[W]e’ve also cherry-picked which international laws we want to stand behind and then, which conflicts we believe the international law is important for and not,” she added. “And you sit in the climate negotiations and they know that you know that they know that you know.”
And yet a hopeful note sounding out of all of this has been the central role of clean energy in many countries’ responses to the increasingly fractious global landscape. Responses to Covid, as chaotic as they were, demonstrated that governments can take decisive action. Although the vast majority of Covid stimulus was climate-neutral at best; about a trillion dollars’ worth of investments really were green. Efforts to boost cycling gained ground in some cities, including in Paris, where bike trips now outnumber car trips in and around the city center.
Renewed interest in energy security sparked by the Ukraine invasion has been largely supportive of clean energy. Europe’s combined wind and solar generation rose 10% in the first year after the invasion as the bloc made its emissions reduction target more ambitious. Green industrial policy introduced by the Biden administration has encouraged other countries to see decarbonization as a competitive opportunity rather than an obligation. And China’s doubling down on its manufacturing of the “new three” — batteries, EVs, and solar panels — has created an oversupply that spurred rapid uptake of clean energy in many countries.
Fractures, however, are rife. Too many countries have steep tariffs on clean energy imports preventing them from taking advantage of cheap Chinese components, adding to other barriers to clean energy generation, such as the restrictive planning rules in Japan, where renewable energy generation lags; even wind power, where the country has ample potential, was virtually flat for the decade to 2022. Tariffs on imports to the U.S., while helping to build a domestic industry, also slow the rate of deployment. Globalized supply chains tend to be cheaper; a study in Nature estimated that they saved the U.S. up to $31 billion in the 12 years leading up to 2020, while China saved up to $45 billion, compared to a scenario in which domestic suppliers were prioritized. Even with its rapid expansion in clean tech manufacturing thanks to the Inflation Reduction Act, it will take years for the U.S. to catch up to China’s capabilities, while in the meantime, tariffs will slow down installations.
For those in wealthier and more powerful countries, there’s at least a chance of political shift. For countries under financial subordination, there are hard limits to what can be achieved.
Geopolitical alignment is an increasingly sensitive question for countries trying to avoid the pitfalls of appearing to be too close to either China or the U.S. Auto manufacturing has become the site of intense competition and tension, with the U.S. and EU putting punitive tariffs on Chinese EV imports to compensate for “state subsidies.” The introduction of the European carbon border adjustment mechanism this year, which penalizes high-carbon imports so they don’t undermine the continent’s carbon pricing regime, has introduced a new source of tension around trade, particularly for African countries that rely on exports to Europe and are nowhere near having their own carbon accounting scheme that is a prerequisite to avoiding the surcharges.
We may only know in retrospect, but the supply bottlenecks and inflationary surges associated with the Covid lockdowns and reopenings may have been a kind of masked transition phase into a new, more permanently supply-constrained world. Researchers at Potsdam Institute and the European Central Bank published new research in March showing that climate change impacts will raise general inflation by more than a percentage point by 2035.
The damage could be seen in the recent COP29 in Azerbaijan. Trust was close to an all-time low over negotiations for a new target for finance flows from wealthy to poor countries. After it ended with a controversially low $300 billion target, Fiona Harvey of the Guardian called it the second worst COP of the 18 she’s attended, surpassed only by the disastrous 2009 COP15 in Copenhagen, which ended with no agreement at all. It can also be seen in the rebound in emissions since 2021.
While some hopeful shifts have emerged from the Covid era, the increasingly febrile global atmosphere risks endangering our already slim chances of protecting the habitable atmosphere. As climate impacts worsen, pushing back on that axiom will be more difficult, but more urgent. Combating climate change is such a monumental undertaking that collaboration – in technology, manufacturing, knowledge, and diplomacy – will be vital.

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
