Heat Killed More Than 2,000 ​People in the U.S.​ Last Year

On deadly temperatures, geothermal deals, and rising sea levels

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.

Q&A

How Building Transmission Could Lower Electricity Costs

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.

The Q&A subject.

This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.

The following Q&A was lightly edited for clarity.

The Solar Farm-to-Data Center Switcheroo Hits a Snag

Plus more of the week’s biggest development fights.

The United States.

1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.

  • On Monday, the Townsite 2 solar farm-to-data center environmental review swap I’ve previously covered received a stay from the Interior Department’s board of appeals. David Gunter, a Biden appointee, ruled that the Center for Biological Diversity’s appeal of the permit flip was likely to succeed on the merits because a solar farm … is not a data center. Seems logical!
  • As I covered at the time, the Bureau of Land Management approved the environmental review swap claiming that a solar farm and a data center have essentially the same characteristics. It was a bold claim. Both the agency and Townsite said the characteristics would have substantially the same environmental impacts. Gunter shrugged off the claim idea, however, stating that statute requires projects to be both substantially similar and have equally similar impacts under the National Environmental Policy Act.
  • Crucially, Gunter also noted that the federal agency had never done an environmental review of any data centers under NEPA, so there’s not even a proper frame of reference. “BLM has not studied the Townsite data center project, or indeed any other data center project, in any environmental document,” he wrote.

2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.

These 5 States Are Primed for a Data Center Pause

Where temporary moratoria could happen next.

Brace yourself for more statewide data center moratoria.

So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
