This is something I have been warning about for months. The US is one of the world's most polluting economies, and it has been exceedingly difficult to breakthrough the dismissiveness. bsky.app/profile/keta...

Higher space heating demand and a growing power
sector
Increased demand for space heating currently correlates directly with increased
emissions, as the majority of homes in the regions with the coldest temperatures rely on
natural gas and other fossil fuels for heat. Colder 2025 winter temperatures led to
increased direct combustion of these fuels in buildings, driving up emissions by 56 million
metric tons (MMT), or 6.8%, compared to 2024.
In the power sector, a 2.4% increase in total electricity generation and a 13% increase in
coal generation relative to 2024 pushed emissions from electricity generation up by 55
MMT (3.8%). This marks only the second year in the last 10 years that coal generation has
increased—a notable departure from its general downward trajectory, in which coal
generation has shrunk by 64% since its peak in 2007. Power sector emissions also
increased in 2024; this stretch marks the first consecutive two-year period of power
sector emissions growth since 2012-2013.
Based on historic and forecasted sectoral consumption data, the largest source of
increased electricity use was commercial buildings, where data centers, cryptocurrency
mining operations, and other large load customers drove electricity demand up by 2.4%.
This growth was concentrated in Texas, the Mid-Atlantic, and the Ohio Valley regions.
Residential buildings saw the next largest increase, with electricity demand up by 2.2%.
This was primarily due to space heating demand from colder winter weather, but electric
vehicle consumption is increasingly a significant contributor. Industrial power demand,
which accounts for a smaller share of total power demand, increased by 1.9% due to
increased output in electricity-intensive subindustries.
The main driver of higher coal use was higher natural gas prices, up 58% at Henry Hub in
2025 compared to very low levels seen in 2024, as a result of high space heating demand
from colder temperatures and rising LNG exports (Figure 4). Generation fr…

- The now-rising emissions above relate mostly to record-high power demand - Most rising power demand in the US comes from new data centres www.iea.org/reports/elec... - Most US data centre expansion comes from generative machine learning applications iea.blob.core.windows.net/assets/b8a83...

dc demand in the us

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Hi folks! Is anyone recruiting masters students that pay a livable stipend? I have an excellent senior who is an incredible researcher and seeking a position. She is top notch and really interested in mechanistic questions- currently working on Aiptasia, Astrangia and Nematostella.

Reason No. 324 why no-one should think that "AI" (artificial but certainly not intelligent) is an unmitigated Good Thing: it's mathematically inevitable that AI will hallucinate. We need far more discussion of the risks of all this and less frantic hype. I mean, really, what's the hurry?

OpenAI admits AI hallucinations are mathematically inevitable, not just engineering flaws

In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limi...

CH₄ has a lifetime of about a decade in the atmosphere, whereby it oxidizes to CO₂ and remains in the atmosphere for tens of thousands of years. More than 99% of the cumulative climate impact (i.e., the radiative forcing) is from its life as CO₂. In the end, it's still CO₂ that gets you. 🥲

My provocation: By 2035, methane - not carbon dioxide - will be the main driver of climate change. Absent significant policy intervention, fossil fuel infrastructure will continue to emit methane at high rates even if fossil fuel combustion, and associated carbon dioxide emissions, drop sharply.

Everyone is acting like US scientists will just go get science jobs elsewhere and sure some will but there are not anywhere close to enough science jobs elsewhere. The end result of this will be much, much, much less science, not science happening in different places.

People are talking about the imminent brain drain of US researchers to other countries but that’s not the only way it’s going to look. There is going to be a brain drain out of science and into other US sectors. There are a lot of non-science things you can do with a Ph.D.

Read news, op-eds, and analysis, not AI summaries. Create your own art (even if it's messy) or hire an artist to do it. Do your own homework. Talk to people, not chatbots. Keep your thinking and skills sharp and cherish our messy humanity. That's the new punk rock.

If a human told you things that were correct 80% of the time but claimed, flat out, with absolute confidence, that they were correct 100% of the time, you would dislike them & never trust a word they say. All I'm really suggesting is for people to treat chatbots with that same distrust & antagonism.

Super important point here-- privatizing GRFP or really anything funding science makes folks doing the work beholden or at least feel beholden to whatever special interest is funding. This drastically impact messaging, results, and even the questions that are asked.

And remember, they are talking about privatizing the National Science Foundation Graduate Research Fellowships, making instruments of government dependent on the largesse of the billionaire military-tech complex www.aip.org/fyi/nsf-seek...

A list of 1753 terminated awards from the NSF. See previous post re: overall funding lost. This is a brain drain and an attack on science and knowledge. It's also NOT strategic at all and places the US at a significant international disadvantage. AND so much more...

NSF just released a public list of terminated awards. It’s linked on the bottom of the FAQ page at: nsf.gov/updates-on-priorities#termination-list
