We’ll Always Have Heat Records

The week in heat, August 5 to 11.

Temperatures may still be scorching, but hey, at least you probably don’t have to swim in the Seine.

Don’t get used to cooler temperatures

The Midwest cooled off a bit over the weekend — but doesn’t mean extreme temperatures are behind us. More heat is in store this week for the Central Plains and the deep South. A heat dome developing in the Western side of the country will push hot air over to those regions, Bryan Jackson, a National Weather Service meteorologist, told me.

“Cities like Denver, Oklahoma City and Kansas City will have temperatures ranging from 95 to 100 degrees Fahrenheit the rest of the work week. That’s 6 to 12 degrees above historical averages,” Paul Pastelok, a senior meteorologist at Accuweather, told me.

The conditions in the Southern Plains across the Gulf States into the interior Southeast will be even more extreme, as high humidity levels will make already high temperatures in cities like Houston, Memphis, Tennessee, Jackson, Mississippi feel 8 to 10 degrees hotter, Pastelok explained. To be clear, that means heat indexes as high as 110.

Over in the West, the heat will focus over eastern Oregon, southern Idaho, Nevada, and central and southern California. According to Pastelok, Boise, Idaho, will see temperatures above 100 degrees for most of this week — 8 to 14 degrees above historical averages.

Olympians are having more trouble staying cool than winning medals

Beyond sleeping in cardboard beds and swimming in the Seine (which is potentially still full of E.coli), athletes are having to deal with the intense heat in the city.

In 2021, Tokyo became the hottest Olympic Games ever, with daily highs averaging nearly 90 degrees and the heat index soaring well past 113 degrees. While Paris won’t come close to challenging that, it’s still been plenty hot. Temperatures in the French capital reached 97 degrees last Tuesday before settling back into the high 70s over the weekend.

To counter the heat, athletes were taking extra breaks to hydrate, but sometimes not even that was enough. “We were drinking hot water out there,” British tennis player Jack Draper told ABC News. USA gymnast-slash-golden girl Simone Biles also complained about the heat and having to go around in a bus without AC. Spectators also struggled, and volunteers had to use a water hose to spray those in the bleachers at a beach volleyball game.

  • Looking Ahead: After a cooler weekend, temperatures in Paris will trend warmer again early this week. The city will likely see temperatures above 86 degrees today and tomorrow, Jason Nicholls, lead international forecaster at Accuweather, told me. That same cycle will repeat again from mid-week through Friday. One spot of good news, though, for those toughing it out in the City of Lights: You’re likely already through the worst of it.

Park Fire rages

The Park Fire is now the fourth largest wildfire in California’s history — and there might still be weeks before it’s quenched. As of this morning, only 31% of the fire had been contained, with one more county being added to the evacuation list. Hundreds of structures have been destroyed, and over 400,000 acres have been burned.

Looking at California’s fire season to date, the numbers are even more shocking. During the summer of 2023, the state responded to 119 wildfire incidents. So far this summer — and remember we still have all of August to go — the state has already responded to 321 wildfires, according to Cal Fire data.

  • Looking Ahead: The chances of putting out the Park Fire this week are low, as “precipitation is not in the forecast to help firefighters,” Pastelok told me. Dry thunderstorms and gusty winds coming from the south to southwest predicted for this week will also make the fire harder to contain. New wildfires in the region can also be expected.

“Extended summer” will last into fall

The first couple of weeks of August will continue to see much of the same extreme heat the country has experienced so far this summer, according to Pastelok. In fact, the Southeast looks to be getting even hotter and more humid late this week and into next. In northern California and parts of Oregon, some cooling may happen around the middle of the month, but not enough to end the wildfire season. More significant opportunities for cooler weather in the region won’t start until September — or even October.

Seattle and Portland may get lucky with a more substantial drop in temperatures later in August, but the Northeast will continue hot and humid throughout all of this month. The location of the cooler weather will mostly be determined by storms, Pastelok explained. “If more storms hit the East coast, the cooling will drive into the Midwest,” he said. “If the storms drive into the Gulf, then warmth will remain back to the Midwest and cooling will be more confined to the northern Rockies and Northwest.”

  • Looking Ahead: From September through November, meteorologists at AccuWeather expect temperatures to be 1 to 3 degrees above historical averages. The only region that will be spared is the Pacific Northwest, where cooler, wetter weather will pop up earlier. This also means that the risk of extreme weather events, such as tornadoes and wildfires, will continue high through the end of the year.

The coldest place on the planet is not even that cold anymore

Not even Antarctica is safe from bizarre temperatures this summer. Last month, an intense heat wave caused temperatures across the continent to average up to 50 degrees above normal. Temperatures were up 82 degrees from historical readings on some days.

The numbers confirm what climate scientists have been telling us for years: Climate change will be most intensely perceived in the polar regions, making temperatures soar even higher in the rest of the globe. Zeke Hausfather, a researcher at Berkeley Earth, told The Guardian that the heat wave in Antarctica was one of the main factors behind the scorching temperatures in the last few weeks.

Extreme weather sends China from drought to drowning

Now major cities in China are also struggling under boiling heat. Shanghai issued its first red warning alert — the most severe temperature alert in the country — for the year last Thursday; the next day, temperatures along the country’s eastern coast hit 104 degrees. On August 3, the city of Hangzhou faced a high of almost 107 degrees, breaking its previous record set in 2022. Warnings have also been issued for the provinces of Fujian, Anhui, Jiangsu, among others, and intense heat is expected to continue through this week.

In Henan province, which had been battling a severe drought after months of no rain, the situation has taken a turn. In late July, the province was hit by a brutal typhoon, leading to the evacuation of tens of thousands.

This year, China recorded its hottest July in history.

Exclusive: U.S. Startup Lands Deal to Develop International AI-for-Nuclear Rules

Atomic Canyon is set to announce the deal with the International Atomic Energy Agency.

Two years ago, Trey Lauderdale asked not what nuclear power could do for artificial intelligence, but what artificial intelligence could do for nuclear power.

The value of atomic power stations to provide the constant, zero-carbon electricity many data centers demand was well understood. What large language models could do to make building and operating reactors easier was less obvious. His startup, Atomic Canyon, made a first attempt at answering that by creating a program that could make the mountains of paper documents at the Diablo Canyon nuclear plant, California’s only remaining station, searchable. But Lauderdale was thinking bigger.

Current conditions: The Northeastern U.S. is bracing for 6 inches of snow, including potential showers in New York City today • A broad swath of the Mountain West, from Montana through Colorado down to New Mexico, is expecting up to six inches of snow • After routinely breaking temperature records for the past three years, Guyana shattered its December high with thermometers crossing 92 degrees Fahrenheit.

THE TOP FIVE

1. Energy Department shells out $800 million to two nuclear projects

The Department of Energy gave a combined $800 million to two projects to build what could be the United States’ first commercial small modular reactors. The first $400 million went to the federally owned Tennessee Valley Authority to finance construction of the country’s first BWRX-300. The project, which Heatmap’s Matthew Zeitlin called the TVA’s “big swing at small nuclear,” is meant to follow on the debut deployment of GE-Hitachi Nuclear Energy’s 300-megawatt SMR at the Darlington nuclear plant in Ontario. The second $400 million grant backed Holtec International’s plan to expand the Palisades nuclear plant in Michigan where it’s currently working to restart with the company’s own 300-megawatt reactor. The funding came from a pot of money earmarked for third-generation reactors, the type that hew closely to the large light water reactors that make up nearly all the U.S. fleet of 94 commercial nuclear reactors. While their similarities with existing plants offer some benefits, the Trump administration has also heavily invested in incentives to spur construction of fourth-generation reactors that use coolants other than water. “Advanced light-water SMRs will give our nation the reliable, round-the-clock power we need to fuel the President’s manufacturing boom, support data centers and AI growth, and reinforce a stronger, more secure electric grid,” Secretary of Energy Chris Wright said in a statement. “These awards ensure we can deploy these reactors as soon as possible.”

2025 has been incredibly eventful for decarbonization — and not necessarily in a good way. The return of Donald Trump, the One Big Beautiful Bill Act, and the rise of data centers and artificial intelligence led to more changes for climate policy and the clean energy sector than we’ve seen in years. Some of those we saw coming. Others we really did not.

On this week’s episode of Shift Key, Rob and Jesse look back at the year’s biggest energy and decarbonization stories and examine what they got right — and what they got wrong. What’s been most surprising about the Trump administration? Why didn’t the Inflation Reduction Act’s policies help prevent the law’s partial repeal? And why have AI and the data center boom become a much bigger driver of power growth than we once thought?
