Current conditions: Typhoon Shanshan is headed toward southwestern Japan with the power of a Category 3 hurricane • Flooding in Bangladesh has killed 23 people and stranded 1.24 million families • Australia just experienced its hottest winter temperature ever recorded.

THE TOP FIVE

1. Midwest heat wave intensifies

Excessive heat warnings and heat advisories are in place across much of the Midwest as a heat wave intensifies across large swathes of Illinois, Indiana, Michigan, Wisconsin, and Ohio. In Chicago, the heat index could climb to 115 degrees Fahrenheit today before temperatures begin to come down Wednesday. But the shifting weather is likely to be accompanied by intense thunderstorms across the Midwest tonight and tomorrow.

2. U.S. heat-related deaths on the rise

Extreme heat killed 2,325 people in America last year, the highest number in nearly 25 years, according to a new study published in the journal American Medical Association. The data shows 21,518 heat-related deaths since 1999, with the number of deaths remaining steady until 2016, when they began to rise noticeably. Last year the number surpassed 2,000 for the first time in the recorded time period. The age-adjusted rate of heat deaths per capita has also been rising. It stood at 0.17 deaths per 100,000 people in 2015, and reached 0.63 last year. “As temperatures continue to rise because of climate change, the recent increasing trend is likely to continue,” the researchers wrote. “Local authorities in high-risk areas should consider investing in the expansion of access to hydration centers and public cooling centers or other buildings with air conditioning.”

3. Meta taps geothermal startup to power data centers

Geothermal startup Sage Geosystems will supply Facebook parent Meta with 150 megawatts of geothermal power in a new deal announced yesterday. The zero-carbon electricity will be used to power Meta’s data centers, starting in 2027, according to a press release. The facility will be built somewhere “east of the Rocky Mountains.” Earlier this month Sage Geosystems became the first geothermal energy storage project to connect to the grid, storing excess clean energy to be used by Texas’ grid operator. This deal with Meta, however, marks Sage’s first move into actually generating around-the-clock, zero-emission electricity by pumping water into the hot rocks that sit beneath the Earth’s surface to create steam. Another geothermal startup, Fervo Energy, is working with Google to power the tech giant’s data centers.

4. Canada hits Chinese EVs with 100% tariffs

Canada announced yesterday it will impose 100% tariffs on Chinese EVs starting October 1 in an effort to prevent cheap cars from flooding the market and threatening Canadian auto manufacturing. New levies might also be applied to other clean technologies, including batteries and solar panels, after a 30-day consultation period. “Actors like China have chosen to give themselves an unfair advantage in the global marketplace, compromising the security of our critical industries and displacing dedicated Canadian autos and metal workers,” said Prime Minister Justin Trudeau. Last year Canada imported $1.6 billion worth of Chinese EVs, up from just $74 million in 2022, according to Bloomberg. The jump coincided with Tesla’s move to ship Model Y vehicles from Shanghai to the port of Vancouver. But as Reuters noted, “Ottawa is trying to position Canada as a critical part of the global EV supply chain and had come under pressure from domestic industry to act against China.” Canada’s move puts it in alignment with the U.S. and the European Union, which have both taken steps to hike tariffs on Chinese EVs.

5. Guterres sounds the alarm about sea level rise

United Nations Secretary-General António Guterres warned yesterday at the Pacific Island Forum Leaders Meeting in Tonga that the “surging seas are coming for us all.” The comments come as two new reports – from the World Meteorological Organization and the U.N. – underscore the growing threat of rising seas for coastal communities and low-lying island nations. Oceans have risen by approximately 9 inches since 1880, and the rate of sea level rise has more than doubled over the past 10 years, driven by melting land ice and the expansion of sea water as it warms.

The Pacific islands are uniquely exposed, the reports say, but the problem is global. Under a scenario in which temperatures rise by 3 degrees Celsius, by 2050 New York City, Boston, New Orleans, and Atlantic City are all expected to see sea levels rise between 9 and 16 inches. “Across the world, around a billion people live in coastal areas threatened by our swelling ocean,” Guterres said. “Yet even though some sea level rise is inevitable, its scale, pace, and impact are not. That depends on our decisions.”

THE KICKER

A typical customer of PG&E will see their electricity bills rise by more than $400 this year to help pay for the California utility’s wildfire risk mitigation efforts.

The World’s First Subsea Geothermal Well Had 8.7 Seconds of Glory

Endurance Energy hoped its generator would run for a full year, but the team isn’t afraid of the “error” in “trial and error.”

About 300 miles off the Oregon coast, a mile beneath the ocean’s surface, a startup just drilled the world’s first subsea geothermal well. And for a grand total of exactly 8.7 seconds, its prototype power plant generated about 2 kilowatts of net power. It wasn’t quite the result the Seattle-based Endurance Energy was hoping for — the company’s goal was to run its 100-kilowatt generator for a full year. But it’s not nothing.

“We really proved with this mission that a geothermal well could be drilled and completed on the seafloor, and doing that within 21 months of the company existing I think is really a testament to our pace of progress,” Endurance CEO Andrew Redd told me.

‘Starting to Fray’

On Greenland’s deepsea mining ban, Indonesia floating nuclear, and a solar boom

Current conditions: Hurricane Trudy has weakened from its peak as a Category 2 storm but still threatens up to 8 inches of rain as it swirls off Baja California • A nor’easter is howling through the Mid-Atlantic this week, hammering the coast with winds of up to 70 miles per hour • A humid overcast has settled over Paris this week as French authorities struggle to regain control after protests over living costs gave way to anarchic riots.


THE TOP FIVE

1. America’s AI infrastructure boom ‘is starting to fray’

At least 47 major data center projects have been delayed, withdrawn, or blocked so far this year, according to data the regulatory intelligence service RegLayer shared with the Financial Times — and that may be a “conservative estimate.” Just 35% of planned data centers are “credible,” analysts told the newspaper, as more than 1,000 communities across the United States now have restrictions on artificial intelligence infrastructure. The data comes as investors look increasingly jittery about AI following ChatGPT-maker OpenAI’s missing a key revenue metric this year.

A Giant Data Center Offers a Permitting Reform Test Case

What would happen to Project Jupiter if the Bipartisan American Affordability and Jobs Act is passed?

One of the nation’s largest data centers is struggling under permitting woes. So let’s play a game: would the bipartisan permitting bill in Congress make the path easier, or might the federal legislation be irrelevant to large hyperscalers under development today?

Meet Project Jupiter, a mega project in southern New Mexico in Dona Ana County under development by Oracle and OpenAI, with financial backing from SoftBank and political support from the Trump administration for being a part of Stargate, a major Trump administration public-private initiative boosting AI development. Project Jupiter would be one of the largest data centers in the country if completed and currently is expected to run on a microgrid powered by fuel cells converting gas to electricity, which the developers claim will burn much cleaner than a typical off-grid gas turbine power plant.
