While the Northeast might start breathing more easily this week, the heat will intensify again in the West. Keep reading to discover what sweltering lies in store.
The weekend brough intense heat to the Northwest, with many cities inching close to their all-time temperature records. While the potential for record-breaking heat is set to decrease throughout the week, temperatures in the region will remain above average, Bob Oravec, lead forecaster with the National Weather Service, told me. Cities like Spokane, Washington and Boise, Idaho will continue to see triple-digit temperatures until at least Wednesday. In fact, on Thursday, Boise might see its 10th day in a row above 100 degrees, breaking the city’s record.
The region also struggled this weekend — and will continue to struggle this summer — with increased wildfire activity. On Saturday, residents of Baker County had to evacuate as a fire spread to residential areas. As of yesterday, Oregon’s firefighters were dealing with 81 active fires, burning through over 500,000 acres of the state. This week, a high pressure area combined with moisture coming from the Pacific Ocean may contribute to thunderstorms — but not enough precipitation to break the dry conditions in the region. The pattern will increase the likelihood of wildfires, as lighting might spark blazes.
All across the East Coast temperatures shattered records last week. On July 16, thermometers in Washington, D.C. reached 104 degrees for just the 13th time in history. The next day the District capped off a run of four days with temperatures above 101 degrees, setting — you guessed it — a new record. And that was just the heat — factoring in humidity, the weather felt more like 108 degrees at its hottest.
In Maryland, summer camps had to move activities indoors for the campers’ safety. Last Monday, only 75 children attended the Horizon Day Camp in Baltimore County. Usually there are around 200 campers.
The heat wave also brought back transit issues across the region. Commuters in the D.C. area and in New York struggled through train cancellations and delays.
In Arizona County alone, more than 300 deaths are being linked to record-breaking heat, NBC News reported on Thursday. Also, 23 deaths in the county have been confirmed to have been caused by heat or heat-related complications — and those numbers are up to date only through July 13, meaning they don’t include last week’s heat. But unlike other parts of the country, the Southwest will continue to broil this week.
“Highs will be closer to historical averages in Phoenix next week, but still above 110 in Las Vegas most days, which could challenge some daily records again later next week,” Dan Pydynowski, senior meteorologist at AccuWeather, told me.
Sorry, California. According to Oravec, for at least the month of August, most of the extreme heat in the U.S. will remain concentrated in the West. That’s not the worst of it, even — conditions will also be very dry. “There’s really not a very good chance of rain across the West, especially across parts of the Northwest and the Great Basin where there’s going to be a lot of record high temperatures,” Oravec told me. When hot and dry conditions occur together, that means wildfires.
On the bright side, CNET reported that California’s investment in solar-powered batteries might have kept the state’s lights on during a heat wave that lasted through July 12. The batteries provided an additional 10,000 megawatts of power.
Sweltering heat continues to spread across Europe. Early last week, Italy placed several cities under its most severe heat alert. The country also reported an increased number of wildfires — two firefighters died while putting out a fire in Southern Italy.
That said, most of the extreme heat hitting the region seems to be in the past now. “If we are looking for extreme heat, chances of that being widespread across Italy to Ukraine looks to be on the low side for the rest of the summer,” Pydynowski told me. In the second half of August, temperatures might return to the high 90s for a while, at least.
In Greece, authorities shut down the Acropolis on Wednesday to protect tourists and workers from extreme temperatures. Earlier in the day, before the closure, Red Cross volunteers were distributing bottled water to those waiting in line for the attraction. Several Greek islands have also been dealing with severe water shortages, and some have resorted to desalinating seawater for drinking and banning the refilling of swimming pools. Next week, the interior and coastal regions of the country will continue to see temperatures around 95 degrees, with the possibility of reaching 104 degrees.

The attacks on Iran have not redounded to renewables’ benefit. Here are three reasons why.
The fragility of the global fossil fuel complex has been put on full display. The Strait of Hormuz has been effectively closed, causing a shock to oil and natural gas prices, putting fuel supplies from Incheon to Karachi at risk. American drivers are already paying more at the pump, despite the United States’s much-vaunted energy independence. Never has the case for a transition to renewable energy been more urgent, clear, and necessary.
So despite the stock market overall being down, clean energy companies’ shares are soaring, right?
Wrong.
First Solar: down over 1% on the day. Enphase: down over 3%. Sunrun: down almost 8%; Tesla: down around 2.5%.
Why the slump? There are a few big reasons:
Several analysts described the market action today as “risk-off,” where traders sell almost anything to raise cash. Even safe haven assets like U.S. Treasuries sold off earlier today while the U.S. dollar strengthened.
“A lot of things that worked well recently, they’re taking a big beating,” Gautam Jain, a senior research scholar at the Columbia University Center on Global Energy Policy, told me. “It’s mostly risk aversion.”
Several trackers of clean energy stocks, including the S&P Global Clean Energy Transition Index (down 3% today) or the iShares Global Clean Energy ETF (down over 3%) have actually outperformed the broader market so far this year, making them potentially attractive to sell off for cash.
And some clean energy stocks are just volatile and tend to magnify broader market movements. The iShares Global Clean Energy ETF has a beta — a measure of how a stock’s movements compare with the overall market — higher than 1, which means it has tended to move more than the market up or down.
Then there’s the actual news. After President Trump announced Tuesday afternoon that the United States Development Finance Corporation would be insuring maritime trade “for a very reasonable price,” and that “if necessary” the U.S. would escort ships through the Strait of Hormuz, the overall market picked up slightly and oil prices dropped.
It’s often said that what makes renewables so special is that they don’t rely on fuel. The sun or the wind can’t be trapped in a Middle Eastern strait because insurers refuse to cover the boats it arrives on.
But what renewables do need is cash. The overwhelming share of the lifetime expense of a renewable project is upfront capital expenditure, not ongoing operational expenditures like fuel. This makes renewables very sensitive to interest rates because they rely on borrowed money to get built. If snarled supply chains translate to higher inflation, that could send interest rates higher, or at the very least delay expected interest rate cuts from central banks.
Sustained inflation due to high energy prices “likely pushes interest rate cuts out,” Jain told me, which means higher costs for renewables projects.
While in the long run it may make sense to respond to an oil or natural gas supply shock by diversifying your energy supply into renewables, political leaders often opt to try to maintain stability, even if it’s very expensive.
“The moment you start thinking about energy security, renewables jump up as a priority,” Jain said. “Most countries realize how important it is to be independent of the global supply chain. In the long term it works in favor of renewables. The problem is the short term.”
In the short term, governments often try to mitigate spiking fuel prices by subsidizing fossil fuels and locking in supply contracts to reinforce their countries’ energy supplies. Renewables may thereby lose out on investment that might more logically flow their way.
The other issue is that the same fractured supply chain that drives up oil and gas prices also affects renewables, which are still often dependent on imports for components. “Freight costs go up,” Jain said. “That impacts clean energy industry more.”
As for the Strait of Hormuz, Trump said the Navy would start escorting ships “as soon as possible.”
“It is difficult to imagine more arbitrary and capricious decisionmaking than that at issue here.”
A federal court shot down President Trump’s attempt to kill New York City’s congestion pricing program on Tuesday, allowing the city’s $9 toll on cars entering downtown Manhattan during peak hours to remain in effect.
Judge Lewis Liman of the U.S. District Court for the Southern District of New York ruled that the Trump administration’s termination of the program was illegal, writing, “It is difficult to imagine more arbitrary and capricious decisionmaking than that at issue here.”
So concludes a fight that began almost exactly one year ago, just after Trump returned to the White House. On February 19, 2025, the newly minted Transportation Secretary Sean Duffy sent a letter to Kathy Hochul, the governor of New York, rescinding the federal government’s approval of the congestion pricing fee. President Trump had expressed concerns about the program, Duffy said, leading his department to review its agreement with the state and determine that the program did not adhere to the federal statute under which it was approved.
Duffy argued that the city was not allowed to cordon off part of the city and not provide any toll-free options for drivers to enter it. He also asserted that the program had to be designed solely to relieve congestion — and that New York’s explicit secondary goal of raising money to improve public transit was a violation.
Trump, meanwhile, likened himself to a monarch who had risen to power just in time to rescue New Yorkers from tyranny. That same day, the White House posted an image to social media of Trump standing in front of the New York City skyline donning a gold crown, with the caption, "CONGESTION PRICING IS DEAD. Manhattan, and all of New York, is SAVED. LONG LIVE THE KING!"
New York had only just launched the tolling program a month earlier after nearly 20 years of deliberation — or, as reporter and Hell Gate cofounder Christopher Robbins put it in his account of those years for Heatmap, “procrastination.” The program was supposed to go into effect months earlier before, at the last minute, Hochul tried to delay the program indefinitely, claiming it was too much of a burden on New Yorkers’ wallets. She ultimately allowed congestion pricing to proceed with the fee reduced from $15 during peak hours to $9, and thereafter became one of its champions. The state immediately challenged Duffy’s termination order in court and defied the agency’s instruction to shut down the program, keeping the toll in place for the entirety of the court case.
In May, Judge Liman issued a preliminary injunction prohibiting the DOT from terminating the agreement, noting that New York was likely to succeed in demonstrating that Duffy had exceeded his authority in rescinding it.
After the first full year the program was operating, the state reported 27 million fewer vehicles entering lower Manhattan and a 7% boost to transit ridership. Bus speeds were also up, traffic noise complaints were down, and the program raised $550 million in net revenue.
The final court order issued Tuesday rejected Duffy’s initial arguments for terminating the program, as well as additional justifications he supplied later in the case.
“We disagree with the court’s ruling,” a spokesperson for the Transportation Department told me, adding that congestion pricing imposes a “massive tax on every New Yorker” and has “made federally funded roads inaccessible to commuters without providing a toll-free alternative.” The Department is “reviewing all legal options — including an appeal — with the Justice Department,” they said.
Current conditions: A cluster of thunderstorms is moving northeast across the middle of the United States, from San Antonio to Cincinnati • Thailand’s disaster agency has put 62 provinces, including Bangkok, on alert for severe summer storms through the end of the week • The American Samoan capital of Pago Pago is in the midst of days of intense thunderstorms.
We are only four days into the bombing campaign the United States and Israel began Saturday in a bid to topple the Islamic Republic’s regime. Oil prices closed Monday nearly 9% higher than where trading started last Friday. Natural gas prices, meanwhile, spiked by 5% in the U.S. and 45% in Europe after Qatar announced a halt to shipments of liquified natural gas through the Strait of Hormuz, which tapers at its narrowest point to just 20 miles between the shores of Iran and the United Arab Emirates. It’s a sign that the war “isn’t just an oil story,” Heatmap’s Matthew Zeitlin wrote yesterday. Like any good tale, it has some irony: “The one U.S. natural gas export project scheduled to start up soon is, of all things, a QatarEnergy-ExxonMobil joint venture.” Heatmap’s Robinson Meyer further explored the LNG angle with Eurasia Group analyst Gregory Brew on the latest episode of Shift Key.
At least for now, the bombing of Iranian nuclear enrichment sites hasn’t led to any detectable increase in radiation levels in countries bordering Iran, the International Atomic Energy Agency said Monday. That includes the Bushehr nuclear power plant, the Tehran research reactor, and other facilities. “So far, no elevation of radiation levels above the usual background levels has been detected in countries bordering Iran,” Director General Rafael Grossi said in a statement.
Financial giants are once again buying a utility in a bet on electricity growth. A consortium led by BlackRock subsidiary Global Infrastructure Partners and Swedish private equity heavyweight EQT announced a deal Monday to buy utility giant AES Corp. The acquisition was valued at more than $33 billion and is expected to close by early next year at the latest. “AES is a leader in competitive generation,” Bayo Ogunlesi, the chief executive officer of BlackRock’s Global Infrastructure Partners, said in a statement. “At a time in which there is a need for significant investments in new capacity in electricity generation, transmission, and distribution, especially in the United States of America, we look forward to utilizing GIP’s experience in energy infrastructure investing, as well as our operational capabilities to help accelerate AES’ commitment to serve the market needs for affordable, safe and reliable power.” The move comes almost exactly a year after the infrastructure divisions at Blackstone, the world’s largest alternative asset manager, bought the Albuquerque-based utility TXNM Energy in an $11.5 billion gamble on surging power demand.
China’s output of solar power surpassed that of wind for the first time last year as cheap panels flooded the market at home and abroad. The country produced nearly 1.2 million gigawatt-hours of electricity from solar power in 2025, up 40% from a year earlier, according to a Bloomberg analysis of National Bureau of Statistics data published Saturday. Wind generation increased just 13% to more than 1.1 gigawatt-hours. The solar boom comes as Beijing bolsters spending on green industry across the board. China went from spending virtually nothing on fusion energy development to investing more in one year than the entire rest of the world combined, as I have previously reported. To some, China is — despite its continued heavy use of coal — a climate hero, as Heatmap’s Katie Brigham has written.

Canada and India have a longstanding special friendship on nuclear power. Both countries — two of the juggernauts of the 56-country Commonwealth of Nations — operate fleets that rely heavily on pressurized heavy water reactors, a very different design than the light water reactors that make up the vast majority of the fleets in Europe and the United States. Ottawa helped New Delhi build its first nuclear plants. Now the two countries have renewed their atomic ties in what the BBC called a “landmark” deal Monday. As part of the pact, India signed a nine-year agreement with Canada’s largest uranium miner, Cameco, to supply fuel to New Delhi’s growing fleet of seven nuclear plants. The $1.9 billion deal opens a new market for Canada’s expanding production of uranium ore and gives India, which has long worried about its lack of domestic deposits, a stable supply of fuel.
India, meanwhile, is charging ahead with two new reactors at the Kaiga atomic power station in the southwestern state of Karnataka. The units are set to be IPHWR-700, natively designed pressurized heavy water reactors. Last week, the Nuclear Power Corporation of India poured the first concrete on the new pair of reactors, NucNet reported Monday.
The Spanish refiner Moeve has decided to move forward with an investment into building what Hydrogen Insight called “a scaled-back version” of the first phase of its giant 2-gigawatt Andalusian Green Hydrogen Valley project. Even in a less ambitious form, Reuters pegged the total value of the project at $1.2 billion. Meanwhile in the U.S., as I wrote yesterday, is losing major projects right as big production facilities planned before Trump returned to office come online.
Speaking of building, the LEGO Group is investing another $2.8 million into carbon dioxide removal. The Danish toymaker had already pumped money into carbon-removal projects overseen by Climate Impact Partners and ClimeFi. At this point, LEGO has committed $8.5 million to sucking planet-heating carbon out of the atmosphere, where it circulates for centuries. “As the program expands, it is helping to strengthen our understanding of different approaches and inform future decision-making on how carbon removal may complement our wider climate goals,” Annette Stube, LEGO’s chief sustainability officer, told Carbon Herald.
