Extreme heat is the deadliest weather phenomenon in the United States. It's also one of the easiest to underestimate: We feel it on our skin, or perhaps see it shimmering in the air around us, but it doesn't announce itself with the destructive aplomb of a hurricane or wildfire. Still, heat waves are becoming practically synonymous with summer.
Climate change is only making heat waves worse. They're getting more frequent, up from an average of two per year in the United States in the 1960s to six per year in the 2010s and '20s. They're also about a day longer than they were in the ‘60s, and they're more intense; those two factors combined, in particular, make them more deadly. This year's expected El Niño will bring even more heat with it: NOAA's summer outlook for the United States, shown below, paints a swath of above-average temperatures across much of the country.

I’ve spent a lot of time thinking about how to cover heat waves. Each is unique — suffering of any kind is always unique, even if the broad strokes are not — yet the things one can say about them are, for the most part, largely the same. Records will break, power grids will strain, and people will be hurt: This is the reality of climate change.
So this year, we are trying an experiment: We will document particularly notable heat waves around the world as they happen, but rather than devote separate stories to them, each heat wave will get a short entry within this larger page. We will call out especially vivid details or statistics and include links to local outlets that can provide more information to anyone looking for it.
The goal here is to create a record of the very real impact of climate change today. By the end of the summer, this page will likely be filled with entry after entry showcasing the ways heat affected people around the world over the course of a few months. This is, I am aware, potentially fertile ground for climate anxiety, but our hope is that the project can help us recognize how our lives are changing and allow us to refocus on what we can do to adapt to our new reality.
Each entry has its own URL. If you wish to share details of any particular heat wave, simply scroll to that entry and hit the share button on your phone or copy the link in your browser. If you'd like to share this tracker as a whole, scroll back up to this introduction. This timeline will be in reverse chronological order, or in other words the newest events will appear at the top of the page.
This project is publishing in the midst of a heat wave hitting multiple Asian countries, and we’ve also included a couple of heat waves that have already come and gone; as the summer progresses, you'll see updates from the entire Heatmap staff and the gradual shaping of a larger story of heat. Again, this is an experiment, and we'd love to hear what you think about it — if you have strong thoughts one way or another, please send them to neel [at] heatmap [dot] news. —Neel Dhanesha
September 6: As we near the end of the summer — though ambient temperatures this week may suggest otherwise — the World Meteorological Organization (WMO) has announced that Earth just had its hottest three-month period on record, and the year so far is the second-warmest after 2016, which saw an extreme El Niño.
“Climate breakdown has begun,” said UN Secretary-General António Guterres in a statement. “Leaders must turn up the heat now for climate solutions. We can still avoid the worst of climate chaos — and we don’t have a moment to lose.”
According to the Copernicus Climate Change Service, August is estimated to have been around 1.5°C warmer than the preindustrial average. Last month saw the highest global average sea surface temperatures on record, at 20.98°C, and Antarctic sea ice was at a record low for that point in the year. Those sea surface temperatures will have a significant impact on hurricane season; as we saw with Idalia, extremely high ocean temperatures can supercharge tropical storms.
These numbers are no surprise — scientists have, of course, been warning of these catastrophic impacts for years — and this report is just the latest in a long line of UN reports that catalog the ways our planet is changing. The question, as always, is if this report will spur any more action than the previous ones did, or whether it will amount to yet another howl lost in the wind. —Neel Dhanesha
August 23-28: On Thursday, record-breaking heat tied the hottest temperature ever recorded in Houston at 109 degrees. In Dallas on Friday, highs climbed into the high 100s. And in Austin on Sunday, the temperature climbed up to 109 degrees. From Thursday to Sunday, the Electricity Reliability Council of Texas issued a conservation request every day — asking Texans to lower their energy use as air conditioners blasted.
Texans will get a relative reprieve from the heat over the coming days: Dallas won’t cross back over the triple-digit mark until Saturday, while Houston won’t get hotter than 100 degrees this week. Still, temperatures remain high — a reminder that just because summer break is over in many places, summer weather isn’t, making air conditioning in schools and on buses more critical than ever. —Will Kubzansky
August 22: The Midwest joins the South and Southwest this week in pulling the short straw of weather forecasts. The National Weather Service projects a large heat dome will “persist in at least 22 states until the end of the week,” Axios reports, affecting 143 million Americans. Numerous cities are experiencing heat indexes between 110 and 115 degrees Fahrenheit; Lawrence, Kansas, even reached a “feels-like” temperature of 134 on Sunday.
Not only will the extreme highs endanger lives, the heat waves might threaten “a bumper U.S. harvest that’s key to keeping global inflation in check,” Bloomberg reports. The United States expects to reap its second largest corn harvest on record this year, but the upcoming heat might dry out fields that are already showing signs of being parched.
Over the weekend, relief for the Midwest will come from cooler winds flowing down from Canada, AccuWeather reports. Unfortunately, the welcome breeze might also come along with “bouts of poor air quality” and smoke from Canadian wildfires. —Annie Xia
August 16: With triple-digit highs, the Pacific Northwest has joined the ranks of states breaking heat records this summer. Portland, Oregon, hit 108 degrees Fahrenheit on Monday, a record for the month of August. Seattle, Washington, also set a new daily record on Monday when it reached 96 degrees.
Combined with strong winds and moderate to severe drought levels, high temperatures in the region also mean heightened wildfire risk. Almost 3,000 firefighters are already “battling the seven large fires burning across Oregon and Washington,” CNN reports.
The sweltering temperatures continue a streak of oppressive summers in the Pacific Northwest. Dr. Steven Mitchell, medical director of a Seattle hospital’s emergency department, told The New York Times that “he couldn’t remember treating a single case of severe heat illness or heat stroke” before 2021, when a deadly heat wave struck the region. —Annie Xia
August 9-11: Florida is often synonymous with heat, but the heat index in Tampa Bay climbed up to 112 degrees on Wednesday — flirting with 113, the mark at which an excessive heat warning is issued. The Tampa Bay Times reported that the warning issued Wednesday was possibly the area’s first excessive heat warning ever, with the caveat that records might be faulty.
While the heat has let up slightly, a heat advisory remains in effect from Fort Myers up to Chiefland, and the area has exceeded its electricity demand records twice this week. On Friday, the heat index at Tampa International Airport reached 110 degrees, and values are expected to climb up to 108 on Saturday, according to the National Weather Service. —Will Kubzansky
August 7: In places like New Orleans, the old adage applies: It’s not just the heat, it’s the humidity. The high is set to hover between 100 and 97 through Friday, but the heat index will sit between 116 and 111. Louisiana, like much of the country, is seeing an unusually hot summer: Baton Rouge experienced its warmest month on record in July. All the while, central Mississippi is experiencing highs between the high 90s and low 100s, with heat indices reaching 120 degrees, according to the National Weather Service’s outpost in Jackson.
The heat killed 16 Louisianans in June and July. And given that extreme heat causes the worst impacts for people experiencing poverty and creates particularly devastating effects for Black Americans, it’s worth noting that Mississippi and Louisiana have the two highest poverty rates in the country as well as the highest proportion of Black residents of any two states. —Will Kubzansky
August 2: Iran is shutting down. The New York Times reports that government agencies, banks, schools, soccer leagues are all closed Wednesday and Thursday, allegedly due to the heat, which is expected to reach 104 degrees Fahrenheit in Tehran. In Ahvaz, a southwestern city, the high on Wednesday is a blistering 123 degrees.
Per the Times, some Iranians have expressed doubts about the alleged reason for the shutdown — instead claiming that the country’s electric grid can’t meet demand. All the while, Iran faces extensive water shortages across the country, largely due to mismanagement of its resources. —Will Kubzansky
August 2: A deadly heat wave is striking both sides of the Sea of Japan.
In South Korea, two deaths were reported on Tuesday due to high heat — they were senior citizens working outside — bringing the death toll from the heat wave to 12. With temperatures above 100 degrees Fahrenheit in Yeoju, a city south of Seoul, the country has raised its warning system for heat to the highest level, the first instance since 2019.
And in Japan, a 13-year-old girl and an elderly couple died due to heat-related causes on Friday. Temperatures have climbed above 103 degrees this week in parts of the country, and 32 prefectures are under the government’s “special heatstroke alert,” according to The Washington Post.
Japan is coming off a brutal month of July, which included the longest run of 95 degree temperatures in Tokyo since records began in 1875. Heat waves are especially devastating for Japan, which has one of the world’s oldest populations. —Will Kubzansky
July 28: No American city has been more emblematic of this summer’s relentless heat than Phoenix, where the temperature has climbed above 110 degrees Fahrenheit for 29 consecutive days. That streak looks like it might finally come to a close, with highs ranging from 106 to 109 from Monday to Wednesday next week as the forecast calls for rain over the weekend. But by Thursday, the mercury will climb above 110 yet again.
With the heat showing no signs of truly relenting, Arizona Democrats have proposed a novel solution — calling on President Joe Biden to issue a presidential disaster declaration for extreme heat, unlocking the Federal Emergency Management Agency’s response capabilities. And all the while, more than 30 wildfires are blazing across the state of Arizona. —Will Kubzansky
July 26: For most of the summer, stories about extreme heat in the U.S. have been limited to the South and Southwest. That’s changed in the last few days, as heat is forecast to scorch the Midwest and Northeast this week. On Thursday, New York will see highs in the mid-90s and D.C. up to 99 — both with heat indexes in the mid-100s. In Kansas City, highs will sit in the 100s through Friday and climb back up into the triple digits again on Monday; Indianapolis will reach 99 degrees Friday.
Late July is an appropriate time for heat waves — and this burst does not look like a lengthy one, with the 10-day forecast dipping back into the 80s — but it’s also worth noting that cities like D.C. are less prepared for extreme heat than Miami or Phoenix. D.C. has entered a hot weather emergency, but in New York, some advocates have cautioned that the city is not ready for the challenges ahead. —Will Kubzansky
July 26: Devastating consequences of the climate crisis are playing out in Algeria, Greece, Italy, and Tunisia, as wildfires spread and take dozens of lives — more than 40 in total and 34 in Algeria alone. The wildfires are being driven in part by intense heat, up to 119.7 degrees Fahrenheit in Algeria and 120 degrees in Tunisia. While those temperatures have cooled slightly, they will reach up to 111 degrees in Tunis come Friday and already climbed into the triple digits in Greece on Wednesday. Meanwhile, Greek authorities have evacuated more than 20,000 people from Rhodes, a popular vacation spot. —Will Kubzansky
July 25: The summer has offered a deluge of heat headlines — scrolling through this page is the proof. But zooming out, the context matters: Has this summer’s heat been uniquely driven by climate change? The answer is almost certainly yes, according to a study from researchers at Imperial College London, the Royal Netherlands Meteorological Institute, and the Red Cross Red Crescent Climate Centre.
The flash study is not peer-reviewed — it moved too quickly to go through that process — but it notes that “without human-induced climate change these heat events would … have been extremely rare.” The high temperatures in North America and Europe, it adds, would have been “virtually impossible” without climate change. Heat waves may have still occurred, but the key is the intensity: In the U.S., Europe, and China, climate change accounted for between 1 to 2.5 degrees Celsius (1.8 to 4.5 degrees Fahrenheit) of additional heat. —Will Kubzansky
July 17: Records are falling left and right in the Southwest. At 118 degrees Fahrenheit, Phoenix broke its all time high temperature record on Saturday. The city is also approaching breaking its record for the most 110 degree days in a row. In El Paso, the temperature at the airport has hit 100 degrees for 32 consecutive days, the longest streak ever. And according to The New York Times, the National Weather Service called for 45 record highs across the U.S. last weekend.
And as wildfires burn in Southern California, the heat wave is showing no signs of letting up. Phoenix will see highs in the 110s through Monday, as will Las Vegas. At this point, the heat wave has been classified as another heat dome, and Texas is feeling the brunt of it too, with San Antonio and Austin under excessive heat warnings. The heat wave is most dangerous for vulnerable members of society, especially people who are homeless and seniors — placing an outsized and crucial burden on cooling centers in the Southwest. —Will Kubzansky
July 14: A year after Europe saw 60,000 excess deaths due to heat waves, according to a study published by the scientific journal Nature Medicine, Southern Europe is scorching again. In Greece, the Acropolis closed midday Friday to tourists with high temperatures in Athens expected to reach 104 degrees. Parts of Spain saw temperatures going up to 113 degrees Monday, and another heat wave is expected to arrive Sunday. Italy, in the meantime, is expecting that next week could break the record for the highest temperatures ever recorded on the continent.
Europe has taken a new approach to heat waves — giving them names like hurricanes in an effort to raise awareness about their severity, an idea my colleague Neel Dhanesha wrote about last year. The first round of heat this week was dubbed Cerberus; the second round set to arrive this weekend is named Charon. —Will Kubzansky

July 12: In a summer full of record-breaking heat, the fact that it’s hot in Death Valley is almost comforting. On Sunday, the national park in the Mojave Desert, known for being the hottest place on Earth, is projected by the National Weather Service to reach 130 degrees Fahrenheit, which would probably tie the record for the world’s highest temperature. The uncertainty stems from some controversy surrounding the record: While the valley was said to have reached temperatures of 134 degrees in 1913, experts have questioned the legitimacy of that reading. That leaves 130 degree days in 2020 and 2021 as the hottest temperatures on record — in Death Valley or anywhere.
While Death Valley’s heat is something of a novelty, it has catastrophic impacts elsewhere. Las Vegas’s high will only be 12 degrees cooler (118 degrees), and temperatures will reach 106 degrees on the same day in San Bernardino. —Will Kubzansky
July 10: After 10 days with high temperatures above 110 degrees, the highs in Phoenix are forecasted to eclipse that mark for at least the next nine days. According to the National Weather Service’s Phoenix office, the record for consecutive 110-degree days is 18; the office is placing the probability that the record gets shattered at 50%. And like Texas’ heat dome earlier this summer, evening temperatures aren’t declining as substantially as they usually do, leaving Arizonans without relief.
In New Mexico, the National Weather Service office out of Albuquerque is describing the week ahead as “near-record heat.” And temperatures in Las Vegas, Nevada, are set to get even more brutal over the course of the week, with the high going from 107 degrees on Monday to a forecasted high of 117 on Sunday. The heat will also lead to brutal temperatures in Death Valley — potentially up to 127 degrees on Sunday — according to the The Washington Post. —Will Kubzansky
July 10: Texas can’t catch a break this summer — and the South is catching yet another heat wave as well. Heat indexes in Dallas, Houston, New Orleans, and Miami are set to reach 107 to 108 degrees this week. Water temperatures around South Florida are well above average, and the chance that rain breaks the heat in the area is limited over the next few days. This year is already the hottest on record in Miami, according to WLRN. —Will Kubzansky
July 7: Phoenix and Tuscon are under excessive heat warnings for at least the next six days. Afternoon highs are projected to reach between 105 and 115 degrees Fahrenheit — Friday will get up to 112 degrees in Phoenix — bringing temperatures above average for early July, according to AZCentral.
It might last well into the month. According to the National Weather System’s warning: “We are still anticipating this current heat wave to continue through next week and likely beyond with it rivaling some of the worst heat waves this area has ever seen.” A big heat wave also brings pressure to the electric grid, particularly in heavily populated areas like Phoenix, as residents crank up their ACs. One study from earlier this year showed that a five-day heat wave and blackout would combine to send more than 50% of the city’s population to the emergency room.
It’s also not just Arizona that will catch the worst of this wave: New Mexico, Las Vegas and Death Valley all have scorching temperatures in store over the next week, The Washington Post notes. —Will Kubzansky

July 6:Outdoor work came to a halt in Beijing as temperatures reached 104 degrees Thursday in the Chinese capital. A heat wave is gripping parts of China, including the capital and the nearby Henan province. Before 2023, Beijing had experienced temperatures above 104 degrees six times, CNN reported. This year alone, the temperature has eclipsed that mark on five days. In Taiwan, temperatures are set to reach 104 degrees Saturday, according to the country’s Central Weather Bureau. All the while, flooding has also led to devastation in China, causing 15 deaths in Chongqing, Hunan province, and elsewhere. —Will Kubzansky
June 30 - July 5: In the Antelope Valley and Santa Clarita Valley, temperatures reached 105 and 101 degrees respectively Monday, the Los Angeles Times reported. David Gomberg, an NWS forecaster, told the Times that high heat is to be expected in Southern California around now — to some extent, the weather is “routine,” he said.
Still, temperatures climbed rapidly in the Los Angeles area beginning Friday, especially inland and in the desert. And because the rise came so suddenly following a temperate period, it may have posed an unusually high risk to Californians who hadn’t yet acclimated to the season’s hotter temperatures. Extreme heat can also create arid conditions begetting wildfires, though no reports of serious fires in California have emerged following July 4 fireworks displays. —Will Kubzansky
July 5: This year’s Fourth of July was the world’s hottest day on record, and that record will likely be broken again this summer. In Texas, the heat was nothing new: The last day El Paso recorded a high temperature under 100 degrees was June 15. Since then, every day has gotten up to the triple digits — with the heat reaching 108 degrees on June 26 and 27.
In other words, it’s still really, really hot in Texas as a heat dome remains firmly planted over the state. Some parts of Texas have seen a handful of cooler days — July 4 wasn’t quite as brutal in Houston, for instance, and San Antonio’s temperatures have largely fallen back into the ‘90s. But the southern part of the state is in what the San Antonio Express-News describes as a “rut”: Heat is giving way to marginally cooler temperatures but the weather is expected to get hotter and more humid again.
For older people or people who work outdoors, the sustained heat has proven especially deadly. The vast majority of Texas’s prisoners, meanwhile, are without air conditioning. —Will Kubzansky
The North Atlantic Ocean is in the middle of a startling heat wave that could have far-reaching repercussions.
The weeks-long marine heat wave broke records for the months of May and is expected to do the same in June. Sea surface temperatures around the U.K. and northern Europe are an astonishing 9 degrees Fahrenheit above average in places, The Washington Post reports.
“Totally unprecedented,” Richard Unsworth, a biosciences professor at the U.K.’s Swansea University, told CNN. It’s “way beyond the worst-case predictions for the changing climate of the region.” Scientists say the warming oceans could have significant consequences, from harming marine life to decreasing the sea’s capacity to absorb pollution.
Above-average heat has also hit the U.K. Temperatures are expected to hit 89 degrees Fahrenheit in southeast England over the weekend.
As a flotilla in the Atlantic searched for the missing Titan submersible, the prominent environmental writer Bill McKibben tweeted, “The truly terrifying news this week is not what happened deep beneath the sea, it’s what’s going on at the surface.” —Annie Xia
June 22: Texans will only get a brief reprieve from the most extreme highs of their heat wave before temperatures pick back up early next week. Notably, temperatures aren’t falling considerably at night, making the heat even more dangerous. North Texas will see the mercury rise up to 104 degrees through Thursday, with the small caveat that humidity will decline into a more comfortable range as the week goes on. In parts of Southwest Texas, the heat won’t let up at all: the high temperatures in Del Rio will hover between 107 and 110 through next Wednesday.
The Electric Reliability Council of Texas issued its first voluntary conservation notice of the heat wave this past Tuesday. While the utility was able to meet demand, it requested that all Texans, especially government agencies, reduce their electricity use.
Mexico is similarly seeing scorching temperatures, which have led to eight deaths already. And high heat in the Rio Grande Valley means that migrants who traverse the border in Southwest Texas could be left exposed to the same high heat, which can have deadly consequences. —Will Kubzansky
Week of June 19: Temperatures in the northern Indian states of Uttar Pradesh and Bihar, two of the most populous in the country, reached as high as 115 degrees Fahrenheit (46 degrees Celsius), CNN reports. The extreme heat triggered power cuts, leaving people without running water, fans, or air conditioners.
The Associated Pressreports nearly 170 people had died as of June 20, overwhelming hospitals, morgues, and crematoria — although state officials dispute the connection to the heat wave. Nearly half of the deaths came from a single district, Ballia, in Uttar Pradesh; officials say they have opened an investigation into the cause, which they say could be linked to contaminated water. Members of opposition parties blame the state government and its chief minister, Yogi Adityanath, for not investing enough in medical facilities or warning residents about the heat wave ahead of time. —Neel Dhanesha
June 19: The numbers from Texas’ heat wave are already striking: Dallas tied a humidity record on Thursday, and tens of millions of Texans woke up Friday to heat advisories or warnings. Temperatures will approach — and possibly break — records in Austin early next week, with highs between 104 and 106 through Wednesday. In the area, the heat indices will be highest over the Rio Grande plains and coastal plains, according to the National Weather Service’s Austin/San Antonio office.
Houston, in the meantime, saw its first excessive heat warning since 2016, with heat indices potentially breaking 115 degrees Friday and Saturday. Texas’ grid has held up (so far) — though the Electric Reliability Council of Texas has projected that next week will shatter the record levels of electricity demand that were just set this week, thanks to the number of air conditioners expected to be on full blast. —Will Kubzansky
June 14: Triple-digit heat has arrived early in Texas. Large parts of central and southeast Texas saw the heat index climb into the 100s Wednesday, topping out in McAllen at a searing 118. The heat wave is expected to spread and last through the week, hitting San Antonio, Dallas, Houston, and Austin, where it will feel like 112 degrees Thursday.
But while meteorologists watch for record heat and humidity, others will keep their eye on the state’s isolated electricity grid. Its operators, the Electric Reliability Council of Texas, warned of record-breaking electricity use Friday, an ominous signal for a state that has struggled with deadly blackouts in recent years. But this is just Texas’s first test of the summer: The grid operators noted that the record-breaking demand will likely be surpassed later in the summer. —Will Kubzansky
June 7-11: As skies over New York and Washington, D.C., turned orange from wildfire smoke, Puerto Rico and nearby Caribbean nations sweltered under a heat dome. The Heat Index, which takes into account both heat and humidity, went as high as 125 degrees in parts of Puerto Rico — a number that Jeff Berardelli, chief meteorologist at Tampa Bay’s WFLA-TV, said was astonishing. Temperature records broke across the island.
The Puerto Rican power grid still hasn’t recovered after Hurricane Maria hit the island in 2017, and over 100,000 Puerto Ricans reportedly lost power (though, as Pearl Marvell pointed out in Yale Climate Connections, the exact number cannot be verified because the island’s power company asked PowerOutage.us, which tracks outages, to stop collecting data on Puerto Rico until it can “replace their technology and provide more accurate data”). As I wrote in May, the combination of extreme heat and blackouts has the potential to be incredibly deadly, though no deaths were reported from this heat dome as of publication. —Neel Dhanesha
June 5: Large parts of China have seen record-breaking heat over the past month, one year after the worst heat wave and drought in decades hit the country. This year, Yunnan and Sichuan provinces saw temperatures exceed 40° C (104° F); according to CNN, heat in some parts of the country was so bad that pigs and rabbits died on farms and carp being raised in rice fields "burned to death" as water temperatures rose. Henan province had the opposite problem; extreme rain flooded wheat fields there, ruining crops in the country's largest wheat-growing region.
Meanwhile, a prolonged heat wave in Vietnam is keeping temperatures between 26 and 38 degrees Celsius (78.8 and 100.4° F), prompting officials to turn off street lights and ask citizens to cut down on their power consumption to avoid blackouts. VNExpress reports that many Vietnamese citizens who can't afford air conditioners are seeking respite in public spaces like libraries, buses, department stores, and cafes. —Neel Dhanesha
May 12: Some 12 million people in Washington and Oregon were under a heat advisory for four days starting May 12 as temperatures in the region topped out at more than 20 degrees above the normal high at that time of year, which should have been in the mid-60s.
"It’s harder for people in the Pacific Northwest to cool down when it’s 90 out than for people in, say, Phoenix or Las Vegas — cities that were constructed with heat in mind," wrote Heatmap Founding Staff Writer and Washington native Jeva Lange in her larger story about this heat wave. "Seattle, for example, is the second-least-air-conditioned metro area in the country (behind only “the coldest winter I ever spent was a summer in” San Francisco). Just over half of the homes in the area have a/c, and many of them are new buildings." —Neel Dhanesha and Jeva Lange
April: A large, deadly heat wave baked much of Asia for two weeks in April,Axios reported. Parts of India saw temperatures beyond 40°C (104°F), while temperatures in Thailand reached their highest levels ever, breaking past 45°C (113°F) for the first time in that country's history. Thirteen people died in Mumbai, and hundreds of people across the Asian continent were hospitalized. —Neel Dhanesha

What he wants them to do is one thing. What they’ll actually do is far less certain.
Donald Trump believes that tariffs have almost magical power to bring prosperity; as he said last month, “To me, the world’s most beautiful word in the dictionary is tariffs. It’s my favorite word.” In case anyone doubted his sincerity, before Thanksgiving he announced his intention to impose 25% tariffs on everything coming from Canada and Mexico, and an additional 10% tariff on all Chinese goods.
This is just the beginning. If the trade war he launched in his first term was haphazard and accomplished very little except costing Americans money, in his second term he plans to go much further. And the effects of these on clean energy and climate change will be anything but straightforward.
The theory behind tariffs is that by raising the price of an imported good, they give a stronger footing in the market; eventually, the domestic producer may no longer need the tariff to be competitive. Imposing a tariff means we’ve decided that a particular industry is important enough that it needs this kind of support — or as some might call it, protection — even if it means higher prices for a while.
The problem with across-the-board tariffs of the kind Trump proposes is that they create higher prices even for goods that are not being produced domestically and probably never will be. If tariffs raise the price of a six-pack of tube socks at Target from $9.99 to $14.99, it won’t mean we’ll start making tube socks in America again. It just means you’ll pay more. The same is often true for domestic industries that use foreign parts in their manufacturing: If no one is producing those parts domestically, their costs will unavoidably rise.
The U.S. imported over $3 trillion worth of goods in 2023, and $426 billion from China alone, so Trump’s proposed tariffs would represent hundreds of billions of dollars of increased costs. That’s before we account for the inevitable retaliatory tariffs, which is what we saw in Trump’s first term: He imposed tariffs on China, which responded by choking off its imports of American agricultural goods. In the end, the revenue collected from Trump’s tariffs went almost entirely to bailing out farmers whose export income disappeared.
The past almost-four years under Joe Biden have seen a series of back-and-forth moves in which new tariffs were announced, other tariffs were increased, exemptions were removed and reinstated. For instance, this May Biden increased the tariff on Chinese electric vehicles to over 100% while adding tariffs on certain EV batteries. But some of the provisions didn’t take effect right away, and only certain products were affected, so the net economic impact was minimal. And there’s been nothing like an across-the-board tariff.
It’s reasonable to criticize Biden’s tariff policies related to climate. But his administration was trying to navigate a dilemma, serving two goals at once: reducing emissions and promoting the development of domestic clean energy technology. Those goals are not always in alignment, at least in the short run, which we can see in the conflict within the solar industry. Companies that sell and install solar equipment benefit from cheap Chinese imports and therefore oppose tariffs, while domestic manufacturers want the tariffs to continue so they can be more competitive. The administration has attempted to accommodate both interests with a combination of subsidies to manufacturers and tariffs on certain kinds of imports — with exemptions peppered here and there. It’s been a difficult balancing act.
Then there are electric vehicles. The world’s largest EV manufacturer is Chinese company BYD, but if you haven’t seen any of their cars on the road, it’s because existing tariffs make it virtually impossible to import Chinese EVs to the United States. That will continue to be the case under Trump, and it would have been the case if Kamala Harris had been elected.
On one hand, it’s important for America to have the strongest possible green industries to insulate us from future supply shocks and create as many jobs-of-the-future as possible. On the other hand, that isn’t necessarily the fastest route to emissions reductions. In a world where we’ve eliminated all tariffs on EVs, the U.S. market would be flooded with inexpensive, high-quality Chinese EVs. That would dramatically accelerate adoption, which would be good for the climate.
But that would also deal a crushing blow to the American car industry, which is why neither party will allow it. What may happen, though, is that Chinese car companies may build factories in Mexico, or even here in the U.S., just as many European and Japanese companies have, so that their cars wouldn’t be subject to tariffs. That will take time.
Of course, whatever happens will depend on Trump following through with his tariff promise. We’ve seen before how he declares victory even when he only does part of what he promised, which could happen here. Once he begins implementing his tariffs, his administration will be immediately besieged by a thousand industries demanding exemptions, carve-outs, and delays in the tariffs that affect them. Many will have powerful advocates — members of Congress, big donors, and large groups of constituents — behind them. It’s easy to imagine how “across-the-board” tariffs could, in practice, turn into Swiss cheese.
There’s no way to know yet which parts of the energy transition will be in the cheese, and which parts will be in the holes. The manufacturers can say that helping them will stick it to China; the installers may not get as friendly an audience with Trump and his team. And the EV tariffs certainly aren’t going anywhere.
There’s a great deal of uncertainty, but one thing is clear: This is a fight that will continue for the entirety of Trump’s term, and beyond.
Give the people what they want — big, family-friendly EVs.
The star of this year’s Los Angeles Auto Show was the Hyundai Ioniq 9, a rounded-off colossus of an EV that puts Hyundai’s signature EV styling on a three-row SUV cavernous enough to carry seven.
I was reminded of two years ago, when Hyundai stole the L.A. show with a different EV: The reveal of Ioniq 6, its “streamliner” aerodynamic sedan that looked like nothing else on the market. By comparison, Ioniq 9 is a little more banal. It’s a crucial vehicle that will occupy the large end of Hyundai's excellent and growing lineup of electric cars, and one that may sell in impressive numbers to large families that want to go electric. Even with all the sleek touches, though, it’s not quite interesting. But it is big, and at this moment in electric vehicles, big is what’s in.
The L.A. show is one the major events on the yearly circuit of car shows, where the car companies traditionally reveal new models for the media and show off their whole lineups of vehicles for the public. Given that California is the EV capital of America, carmakers like to talk up their electric models here.
Hyundai’s brand partner, Kia, debuted a GT performance version of its EV9, adding more horsepower and flashy racing touches to a giant family SUV. Jeep reminded everyone of its upcoming forays into full-size and premium electric SUVs in the form of the Recon and the Wagoneer S. VW trumpeted the ID.Buzz, the long-promised electrified take on the classic VW Microbus that has finally gone on sale in America. The VW is the quirkiest of the lot, but it’s a design we’ve known about since 2017, when the concept version was revealed.
Boring isn’t the worst thing in the world. It can be a sign of a maturing industry. At auto shows of old, long before this current EV revolution, car companies would bring exotic, sci-fi concept cars to dial up the intrigue compared to the bread-and-butter, conservatively styled vehicles that actually made them gobs of money. During the early EV years, electrics were the shiny thing to show off at the car show. Now, something of the old dynamic has come to the electric sector.
Acura and Chrysler brought wild concepts to Los Angeles that were meant to signify the direction of their EVs to come. But most of the EVs in production looked far more familiar. Beyond the new hulking models from Hyundai and Kia, much of what’s on offer includes long-standing models, but in EV (Chevy Equinox and Blazer) or plug-in hybrid (Jeep Grand Cherokee and Wrangler) configurations. One of the most “interesting” EVs on the show floor was the Cybertruck, which sat quietly in a barely-staffed display of Tesla vehicles. (Elon Musk reveals his projects at separate Tesla events, a strategy more carmakers have begun to steal as a way to avoid sharing the spotlight at a car show.)
The other reason boring isn’t bad: It’s what the people want. The majority of drivers don’t buy an exotic, fun vehicle. They buy a handsome, spacious car they can afford. That last part, of course, is where the problem kicks in.
We don’t yet know the price of the Ioniq 9, but it’s likely to be in the neighborhood of Kia’s three-row electric, the EV9, which starts in the mid-$50,000s and can rise steeply from there. Stellantis’ forthcoming push into the EV market will start with not only pricey premium Jeep SUVs, but also some fun, though relatively expensive, vehicles like the heralded Ramcharger extended-range EV truck and the Dodge Charger Daytona, an attempt to apply machismo-oozing, alpha-male muscle-car marketing to an electric vehicle.
You can see the rationale. It costs a lot to build a battery big enough to power a big EV, so they’re going to be priced higher. Helpfully for the car brands, Americans have proven they will pay a premium for size and power. That’s not to say we’re entering an era of nothing but bloated EV battleships. Models such as the overpowered electric Dodge Charger and Kia EV9 GT will reveal the appetite for performance EVs. Smaller models like the revived Chevy Bolt and Kia’s EV3, already on sale overseas, are coming to America, tax credit or not.
The question for the legacy car companies is where to go from here. It takes years to bring a vehicle from idea to production, so the models on offer today were conceived in a time when big federal support for EVs was in place to buoy the industry through its transition. Now, though, the automakers have some clear uncertainty about what to say.
Chevy, having revealed new electrics like the Equinox EV elsewhere, did not hold a media conference at the L.A. show. Ford, which is having a hellacious time losing money on its EVs, used its time to talk up combustion vehicles including a new version of the palatial Expedition, one of the oversized gas-guzzlers that defined the first SUV craze of the 1990s.
If it’s true that the death of federal subsidies will send EV sales into a slump, we may see messaging from Detroit and elsewhere that feels decidedly retro, with very profitable combustion front-and-center and the all-electric future suddenly less of a talking point. Whatever happens at the federal level, EVs aren’t going away. But as they become a core part of the car business, they are going to get less exciting.
Current conditions: Parts of southwest France that were freezing last week are now experiencing record high temperatures • Forecasters are monitoring a storm system that could become Australia’s first named tropical cyclone of this season • The Colorado Rockies could get several feet of snow today and tomorrow.
This year’s Atlantic hurricane season caused an estimated $500 billion in damage and economic losses, according to AccuWeather. “For perspective, this would equate to nearly 2% of the nation’s gross domestic product,” said AccuWeather Chief Meteorologist Jon Porter. The figure accounts for long-term economic impacts including job losses, medical costs, drops in tourism, and recovery expenses. “The combination of extremely warm water temperatures, a shift toward a La Niña pattern and favorable conditions for development created the perfect storm for what AccuWeather experts called ‘a supercharged hurricane season,’” said AccuWeather lead hurricane expert Alex DaSilva. “This was an exceptionally powerful and destructive year for hurricanes in America, despite an unusual and historic lull during the climatological peak of the season.”

This year’s hurricane season produced 18 named storms and 11 hurricanes. Five hurricanes made landfall, two of which were major storms. According to NOAA, an “average” season produces 14 named storms, seven hurricanes, and three major hurricanes. The season comes to an end on November 30.
California Gov. Gavin Newsom announced yesterday that if President-elect Donald Trump scraps the $7,500 EV tax credit, California will consider reviving its Clean Vehicle Rebate Program. The CVRP ran from 2010 to 2023 and helped fund nearly 600,000 EV purchases by offering rebates that started at $5,000 and increased to $7,500. But the program as it is now would exclude Tesla’s vehicles, because it is aimed at encouraging market competition, and Tesla already has a large share of the California market. Tesla CEO Elon Musk, who has cozied up to Trump, called California’s potential exclusion of Tesla “insane,” though he has said he’s okay with Trump nixing the federal subsidies. Newsom would need to go through the State Legislature to revive the program.
President-elect Donald Trump said yesterday he would impose steep new tariffs on all goods imported from China, Canada, and Mexico on day one of his presidency in a bid to stop “drugs” and “illegal aliens” from entering the United States. Specifically, Trump threatened Canada and Mexico each with a 25% tariff, and China with a 10% hike on existing levies. Such moves against three key U.S. trade partners would have major ramifications across many sectors, including the auto industry. Many car companies import vehicles and parts from plants in Mexico. The Canadian government responded with a statement reminding everyone that “Canada is essential to U.S. domestic energy supply, and last year 60% of U.S. crude oil imports originated in Canada.” Tariffs would be paid by U.S. companies buying the imported goods, and those costs would likely trickle down to consumers.
Amazon workers across the world plan to begin striking and protesting on Black Friday “to demand justice, fairness, and accountability” from the online retail giant. The protests are organized by the UNI Global Union’s Make Amazon Pay Campaign, which calls for better working conditions for employees and a commitment to “real environmental sustainability.” Workers in more than 20 countries including the U.S. are expected to join the protests, which will continue through Cyber Monday. Amazon’s carbon emissions last year totalled 68.8 million metric tons. That’s about 3% below 2022 levels, but more than 30% above 2019 levels.
Researchers from MIT have developed an AI tool called the “Earth Intelligence Engine” that can simulate realistic satellite images to show people what an area would look like if flooded by extreme weather. “Visualizing the potential impacts of a hurricane on people’s homes before it hits can help residents prepare and decide whether to evacuate,” wrote Jennifer Chu at MIT News. The team found that AI alone tended to “hallucinate,” generating images of flooding in areas that aren’t actually susceptible to a deluge. But when combined with a science-backed flood model, the tool became more accurate. “One of the biggest challenges is encouraging people to evacuate when they are at risk,” said MIT’s Björn Lütjens, who led the research. “Maybe this could be another visualization to help increase that readiness.” The tool is still in development and is available online. Here is an image it generated of flooding in Texas:
