Grid scale batteries are changing our electricity system. Excellent new visual story on batteries in FT today shows just how far this technology has evolved.

Fasten your seatbelts, this is just the beginning.

A new study published in Nature Climate Action finds Woodside’s Scarborough gas project could cause 100s of heat-related deaths & exposed 500k people to unprecedented heat.

Govt can’t claim climate leadership while approving projects like this.

Forrest-backed study links Woodside mega-project to hundreds of deaths
The research, conducted by academics at ANU, suggests the massive offshore gas project off the coast of Western Australia will cause warming of 0.00039 degrees.

"Currently, data centres in China use between 0.9% and 2.7% of the country’s annual electricity, according to different estimates"

"By 2030, China’s data centres are projected to consume anything from 400TWh to 600TWh of electricity, with associated emissions of perhaps 200MtCO2e"
Explainer: How China is managing the rising energy demand from data centres - Carbon Brief
The rise of artificial intelligence (AI) has driven the “surging” growth of data centres in China, with associated increases in energy demand and emissions

This Republican US Senator is kind of neatly laying out the centre-right vision for renewables

- No wind, only solar / batteries
- No displacement of fossil fuels; only supplementing
- Mostly there to serve data centre / AI power demand

This isn't something to celebrate or welcome. It's v v bad

This is how we lose the AI/energy arms race with China. Our country needs an all-of-the-above approach to energy (like Utah). We should be all in on nuclear/natural gas/geothermal and keeping our coal plants open for as long as possible. However, there are innovation/permitting/supply chain issues slowing those down. While intermittent sources have been overvalued in the past (and offshore wind is a disaster and should be discontinued), the incredible leaps in battery technology completely change the value proposition of solar in the right places. Solar with batteries can now be close to baseload power and we should keep these projects rolling until we get the gas/nuclear/geothermal plants we need.

This is a great, detailed piece of work. There is really no secret here: OpenAI fully intend to use fossil gas to power their data centres.

All the crap about fusion, dyson spheres etc is misdirection. This is what they're *actually* doing:

www.desmog.com/2025/10/13/o...
John McCarrick, the company’s new head of Global Energy Policy, was a senior energy policy advisor in the first Trump administration’s Bureau of Energy Resources in the Department of State while under former Secretaries of State Rex Tillerson and Mike Pompeo.
 
As deputy assistant secretary for Energy Transformation and the special envoy for International Energy Affairs, McCarrick promoted exports of American liquefied natural gas to Europe in the wake of the Russian invasion of Ukraine, and advocated for Asian countries to invest in natural gas.

The choice to hire McCarrick matches the intentions of OpenAI’s Trump-donating CEO Sam Altman, who said in a U.S. Senate hearing in May that “in the short term, I think [the future of powering AI] probably looks like more natural gas.”
 
 It also aligns with the company’s early moves toward powering new data centers, huge warehouses full of linked-up computers that require enormous quantities of water and electricity, to run with gas. OpenAI’s U.S. Stargate Project site in Texas, which is slated to become one of the largest data center sites in the world, is already installing off-grid gas turbines to power its operations.

“Big Tech’s collusion with the Trump administration’s fossil fuel agenda for artificial intelligence is evident in their massive investment in methane gas power infrastructure — as well as pro-gas political operatives like McCarrick,” Tyson Slocum, director of consumer advocacy organization Public Citizen’s Energy Program, said.
 
The “solution” of powering AI with gas is part of Trump’s AI energy policy platform.  In a July speech to announce a $96 billion AI and energy funding package, Trump lauded fossil fuel and coal-powered data center development while flanked by oil and gas executives.

Microplastics are released from plastic when exposed to heat, including leaching from tea bags into hot tea and plastic containers releasing nanoplastics when microwaved. While health effects are still unclear, minimizing heating plastic is a simple way to reduce exposure.
Microplastics are everywhere. You can do one simple thing to avoid them.
The biggest sources of microplastics have one thing in common: Heat.

Timor-Leste just scrapped lifetime pensions for former parliamentarians after student-led protests.

But sure — protest doesn’t work.

In short
Protests broke out last week in Timor-Leste, with thousands of demonstrators demanding parliament cancel a $4.2 million plan to purchase SUVs for lawmakers and lifetime pension for MPs and public officials.

Sixty-two members of parliament voted unanimously on Friday to pass a new law that scrapped the pensions for MPs, former presidents, prime ministers and cabinet ministers.

This morning was the first frost and freeze for many across the Northeast. As a snow/winter fan, I am very excited! 🥶

Any academic willing and able to leave the US would do it in the Trump era. There aren’t that many places that pay academics as well as the US but Switzerland is definitely one that does (in fact it pays way more).

Friday ice update - #Arctic sea ice extent is currently the 11th lowest on record (JAXA data)

• about 20,000 km² below the 2010s mean
• about 1,300,000 km² below the 2000s mean
• about 2,400,000 km² below the 1990s mean
• about 3,040,000 km² below the 1980s mean

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between August and November by looking at the decadal average line positions.

All the lip gloss being put on the AI boom as somehow good for climate or the energy transition is masking that, at the present moment, it's a disaster.

Not only more gas generation, but the worst, dirtiest, least efficient kind. Turning the clock back 25 years.
