1. Three Mile Island nuclear plant to come back online to power Microsoft data centers
We’ll start with some breaking news today: Pennsylvania’s Three Mile Island nuclear plant, the site of an infamous 1979 partial reactor meltdown, will be revived by 2028 as part of a plan to provide power for Microsoft’s data centers. Constellation Energy, the plant’s owner and the largest nuclear operator in the country, announced the news today. Microsoft agreed to buy all of the plant’s power for 20 years – enough energy to power 800,000 homes.
If approved, this decision “would mark a bold advance in the tech industry’s quest to find enough electric power to support its boom in artificial intelligence,” The Washington Post reported. “The symbolism is enormous,” Joseph Dominguez, chief executive of Constellation, told The New York Times. “This was the site of the industry’s greatest failure, and now it can be a place of rebirth.”
“Now, THIS is additional clean supply,” said Heatmap Shift Key co-host Jesse Jenkins. “Bravo. It is remarkable to see a handful of nuclear reactors shuttered in the last decade due to poor revenues contemplating restart now. Palisades, now TMI. Who is next? Maybe it was unwise to let these plants close in the fist place eh?”
2. World Bank climate financing reaches record high
The World Bank Group yesterday announced it delivered a record $42.6 billion in climate finance in fiscal year 2024 (which ran from July to June), a 10% increase year-over-year. Climate financing made up 44% of the group’s total lending, which is awfully close to its goal, set at COP28, of 45% for fiscal year 2025. However this remains “well short of the trillions of dollars in additional resources needed annually to finance the clean energy transition in emerging markets and developing countries,” noted Reuters.
3. Equatic starts producing its breakthrough anode
Carbon removal startup Equatic announced it has started manufacturing its “oxygen-selective anode,” which has the potential to pave the way for a two-for-one climate solution: commercial hydrogen production and carbon removal. Equatic wants to use seawater electrolysis – sending an electrical current through seawater – to sequester carbon dioxide from the air in the ocean while also producing hydrogen. But as Heatmap’s Emily Pontecorvo reported, electrolysis tends to turn the salt in the water into the toxic and corrosive gas chlorine, which makes commercializing such a process challenging. So Equatic set out to find the right combination of catalysts to make an anode – a sheet of conductive, positively-charged metal – that, when used in electrolysis, would screen out the salt and not allow it to react. Using ARPA-E funding, they landed on a design that produced less than one part per million of chlorine (lower than the amount in drinking water) and performed reliably for more than 20,000 hours of testing.
The company’s San Francisco facility will be able to produce 4,000 of these anodes per year to start, and is expected to operate at full capacity by the end of 2024. It will produce the anodes for Equatic’s first demonstration-scale project, a new plant in Singapore designed to remove 10 metric tons of CO2 and produce 300 kilograms of hydrogen per day — 100 times larger than the pilot version. Equatic also has plans to build an even bigger plant in Quebec that can remove 300 tons per day. That’s about three times the capacity of Climeworks’ Mammoth plant, the world’s largest direct air capture plant operating today.
4. Outlook for Doomsday Glacier looking ‘grim’
Scientists who spent six years examining the Thwaites Glacier in Antarctica warned this week that the outlook for the glacier is “grim.” Thwaites, often referred to as the “Doomsday Glacier,” is massive, spanning an area equal to the state of Florida. It has been retreating for nearly a century, but this melting has accelerated significantly over the last 30 years and the new research suggests it is set to worsen. Within 200 years, the glacier could collapse, raising sea levels worldwide. CNN succinctly summarized why this matters:
“Thwaites holds enough water to increase sea levels by more than 2 feet. But because it also acts like a cork, holding back the vast Antarctic ice sheet, its collapse could ultimately lead to around 10 feet of sea level rise, devastating coastal communities from Miami and London to Bangladesh and the Pacific Islands.”
Dr. Ted Scambos, U.S. science coordinator of the International Thwaites Glacier Collaboration and glaciologist at the University of Colorado, said “immediate and sustained climate intervention will have a positive effect, but a delayed one.”

5. WRI considers city life at 3 degrees Celsius of warming
A sweeping new report from the World Resources Institute paints a bleak picture of what 996 of the world’s biggest cities will feel like in a world that is 1.5 degrees Celsius warmer than pre-industrial records, and compares that to a scenario in which temperatures warm by 3 degrees Celsius. Here are some stats:
- 6.4 – heat waves, on average, cities will experience each year with 3 degrees C of warming, compared to 4.9 heat waves annually at 1.5 degrees C of warming.
- 24.5 – average length, in days, of the year’s longest heat wave at 3 degrees C of warming, compared to 16.3 days for 1.5 degrees C of warming.
- 16 – percentage of big cities that would experience a heat wave that lasts for a month or longer annually at 3 degrees C of warming.
- Two-thirds – the share of the global population that will live in cities by 2050.
The report also looks at what warmer temperatures mean for mosquito-borne diseases. Some, like dengue, Zika, and West Nile, will become more common. But malaria could actually decline “as temperatures in many places become warmer than what is optimal for malaria-transmitting mosquitos.”
