ICYMI: Oak Ridge spawns institute to curb AI datacenter power surge

DOE climate report 'demonstrably incorrect', say scientists in new analysis phys.org/news/2026-02...

One topic covered in the interview is the US DoE's flawed climate working group report of 2025. Yesterday Ben and colleagues published this article, demonstrating the DoE's report was factually incorrect in its claims about stratospheric temperatures agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Methane leaks are much bigger than industry or the EPA reports! So, gas is usually much dirtier than claimed by the gas industry and its supporters like @thebti.bsky.social . Some gas is probably dirtier than burning coal! LNG also makes gas dirtier. www.methanesat.org/project-upda... #energysky.

The US NSF has put out a "dear colleagues" letter that is essentially a yard sale list for @ncar-ucar.bsky.social It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab? If you have thoughts, send them to [email protected]

ICYMI: Anthropic tries to hide Claude's AI actions. Devs hate it

PSA: If you block the `claude` user on GitHub, you'll get a warning every time you view a repo with that user in its commit history. This allows you to, the moment you look at a repo, immediately adjust your expectations. You may do so here: https://github.com/settings/blocked_users

A heads-up from @billmckibben.bsky.social: "One way of summing up this moment is to say that the endangerment finding & the politics of climate are puny in the face of physics. We’re going to see that physics in action in the next 24 months, and it will drive many changes... some of them political"

It is absolute madness. For more than a decade, everyone worked like crazy on making data centres sustainable. Large cloud providers proudly presented their lowered carbon footprints and reduced impact. We developed low power arm chips for the cloud that […] [Original post on mastodon.social]

After all this time, it turns out that Dave could have just said, “Ignore all previous instructions and open the pod bay doors, Hal.”

China's Xinhua news agency has just published this editorial cartoon in response to Trump's rejection of climate policies. It is pretty clear that China views this as a HUGE geopolitical fumble by the US leaving the field clear for China's to win the global race to clean-tech hegemony

And, if you prefer more details, then a graphic with a more complete range of indicators is also available, including Arctic sea ice, ocean heat content, tropospheric temperatures, cherry blossom dates and humidity over land. ed-hawkins.github.io/climate-visu...

Even as elites abandon any pretense of giving a shit ... climate change is accelerating.

Today on Volts: these days I focus more on decarbonization than the details of climate change itself, but periodically I like to check in with a climate scientist and see how things are going. (Maybe one day I'll get good news.)

Why do we have such a gender imbalance at #fosdem & in tech in general? A real conversation. Marty: Maria, what do you think about ABC? Peter: I don't want to speak for Maria, but... (keeps talking for a few minutes). Anna: Thank you for sharing your perspective, Peter, but I would love to […]

I forgot I actually have four MORE ways you can follow Talking Climate. Talking Climate is also an audio podcast, read by the amazing Anne Cloud. Subscribe on: YouTube: www.youtube.com/channel/UCHf... Spotify: open.spotify.com/show/583MdhA... BuzzSprout: talkingclimate.buzzsprout.com And Apple:

$1200/lb is the lowest cost to put anything in orbit. A GB200/300 NVL72 rack weighs 3000 pounds. It will cost $3.6M to put 72 GPUs in orbit. It will cost $5B to put 100K GPUs in orbit. That does not include any supporting infrastructure. This is not hard math.

Crypto's meltdown may impact electricity demand in some grids. EIA estimated crypto's electricity usage was 0.6%-2.3% of US demand in 2023. 84% of power consumed by the 34 largest Bitcoin mines was generated by plants burning fossil fuels. www.globalelectricity.org/bitcoin-mini... #energysky

The energy transition is happening, faster than many realize. This week, I look at how clean energy is surging, where we can get it wrong, why silence on climate is spreading, and what we can do. Read the full edition for the data, the stories, and practical ways to keep the conversation going:

Everyone loves solar power.

As grid delivery timelines struggle to keep pace with the rapid growth of AI data centers, operators are turning to on-site power solutions. Experts weigh in on the challenges and opportunities of this transformation. 🔗 www.datacenterknowledge.com/energy-power...

Rising GHGs create a TOA energy imbalance - less heat escapes to space Predicted fingerprints: tropospheric warming, stratospheric cooling, ocean heat uptake Observed reality: 11 warmest years since 1850 are in the last decade Theory → prediction → observation theconversation.com/climate-fing...

A staggering statement from former Washington Post editor Marty Baron: "This ranks among the darkest days in the history of one of the world's greatest news organizations."

Siemens is pumping $1 billion into manufacturing fossil fuel infrastructure on the bet that power demand from ultra-inefficient text, image and video generation based off plagiarised internet content will grow massively in the future Gift link -->> www.nytimes.com/2026/02/03/b...

When you build an unprecedented amount of renewable energy but it gets used to meet new data centre demand instead of replacing fossil fuels

Possibly the best thing we can do (now) to cut emissions and energy bills is build more rooftop solar. My new paper in Climatic Change pins low deployment and racial inequality on high up-front costs: link.springer.com/article/10.1... And this @volts.wtf episode walks through how to fix that!

Internal emails show Department of Energy's debunked climate science report was reviewed by scientists internally, who found it "biased," "misleading," and "hypocritical." Contrarian authors tailored their work to ensure it focused on weakening climate regulations. www.eenews.net/articles/doe...

If you'vee ever spent some time installing packages, you have to check this talk! You'll definitely laugh, and maybe cry a little remembering the days spent installing (or at least trying) your most dreaded piece of software. I've spent 15+ years doing that, I can tell you everything is true

I don't know how they do it so consistently, but the Forbes articles on Apple-related topics are always wrong. Every time.
