The US could see a 30-40% decline in new international student enrollment, resulting in nearly $7 billion in lost revenue and more than 60,000 fewer American jobs. https://www.nafsa.org/fall-2025-international-student-enrollment-outlook-and-economic-impact

It has to explain the global set of tide gauges, satellite altimetry, paleo proxies, observations of land ice changes and ocean heat, undedatanding of physics, etc. And human caused acceleration of global-mean sea level rise is clearly from the body of evidence

Your explanation of how the world work can’t just be based on looking at cherry picked tide gauges in isolation as though they were stock market indices.

If the only piece of info you had were the NY tide gauge time series, it’d be reasonable to question whether sea level rise is accelerating or long period variability, as they do. BUT…

I don’t actually agree with Tamino’s critique here - like the DOE report it misses the main point. At New York, for instance, the DOE folk would point out that the rate over 1930-1950 was high, just like the rate over the last 20 years.

Sea Level Mis-information from DOE Here in the USA, the Department of Energy (DOE) has issued a report titled “A Critical Review of the Impacts of Greenhouse Gas Emissions on the U.S. Climate.” It is a product of the &#8…

That's just one of many instances of distortion and misinformation in the US Department of Energy "Critical Review on the Impacts of Greenhouse Gas Emissions".
Which in fact is a fossil fuel propaganda scam.
Let's hope Americans are not that easily fooled.

And the EPA wants to say climate change is not a threat to human health (highly toxic smoke across much of the US is ok?) and welfare (whole towns cities burning is ok?). What are those climate deniers smoking?!

Good article but I feel this also goes beyond the national angle. The decline in the scientific dominance of the US won't just hurt them, it could delay global scientific progress where other states don't have the drive, resources or concentrated expertise to carry on the momentum. /1

August 1, 2025 AMERICAN ECONOMIC ASSOCIATION Committee on Economic Statistics and Committee on Government Relations Statement from the American Economic Association on the Dismissal of the BLS Commissioner Leaders of the American Economic Association express their grave concern over the dismissal of the Commissioner of the Bureau of Labor Statistics (BLS) earlier today. The independence of the federal statistical agencies is essential to the proper functioning of a modern economy. Accurate, timely, and impartial statistics are the foundation upon which households, businesses, and policymakers make critical decisions. Undermining the independence or credibility of these agencies threatens the integrity of the information that markets, institutions, and the public rely on every day. Measuring the vast and dynamic U.S. economy in real time is inherently challenging. It is standard practice for statistical estimates to be revised as more complete and higher-quality data become available. These revisions reflect the commitment of statistical agencies to accuracy, transparency, and methodological rigor-not failure or bias. The BLS has long had a well-deserved reputation for professional excellence and nonpartisan integrity. Safeguarding this tradition is vital for the continued health of the U.S. economy and public trust in our institutions. We call upon elected officials to respect and preserve the independence of the nation's statistical infrastructure. Lawrence Katz President, American Economic Association Katharine Abraham President-Elect, American Economic Association Karen Dynan Chair, American Economic Association Committee on Economic Statistics Kenneth Troske Chair, American Economic Association Committee on Government Relations

This is a big deal

Rising Carbon Dioxide and Global Nutrition: Evidence and Action Needed While the role of CO2 as a greenhouse gas in the context of global warming is widely acknowledged, additional data from multiple sources is demonstrating that rising CO2 of and by itself will have a t...

Not my expertise, but the studies I’ve read suggest higher carbohydrate fractions and lower protein and micronutrients under higher CO2

ADL Musk

I spoke with 40+ sources for a look inside the Anti-Defamation League. Here’s some of what I found.

ADL’s gentle response to Elon Musk’s infamous salute was partially driven by his support of Israel. To ADL, that indicated he didn’t have “antisemitic tendencies.” (1/x)

Impacts of climate change on global agriculture accounting for adaptation - Climate Impact Lab We explore the impacts of climate change on global agriculture while accounting for adaptation.

Anyways, have some empirically based crop yield projections

The report is "tedious" and at times "truly wearisome", according to Bob Kopp, a climate scientist at Rutgers University. Kopp recently worked on a paper showing how rising temperatures and drought will worsen crop yields, counter to the report's claims that crops will flourish with extra carbon dioxide in the atmosphere. "Carbon dioxide fertilization is largely irrelevant to how increasingly extreme heat and intense drought will impact crop yields," Kopp said. "As a former department of energy fellow, I'm embarrassed by this report."

I’m tired and no longer capable of being measured when speaking to reporters…

Artificial Intelligence and Academic Professions Executive SummaryEducational technology, or ed-tech, including artificial intelligence (AI), continues to become more integrated into teaching and research in higher education, with minimal oversight.

I hope that faculty across the country read this report from the AAUP on AI & the Academic Professions, share it with their university administrators,& collectivize to create communities that use this document as a roadmap towards gaining agency over higher education. www.aaup.org/reports-publ...

This parody is too plausible…

I would have been surprised if these authors hadn’t used a LLM to remix their past papers into this report.

Firing the BLS Commissioner — the wonk in charge of the statisticians who track economic reality — is an authoritarian four alarm fire.

It will also backfire: You can't bend economic reality, but you can break the trust of markets. And biased data yields worse policy.

I think that would still get stuck in the PJM interconnection queue unless PJM is reformed.

Nice video by @mikiesherrill.bsky.social on PJM and the need to let more renewable projects come online.

We fact-checked the Trump administration’s climate report Scientists say the report cherry-picks key data and misrepresents the state of climate research.

“We fact-checked the Trump administration’s climate report”

What scientists have to say about the recent DOE ‘climate report’. Good journalism.

With federal involvement in the next IPCC report uncertain, AGU joined 10 U.S. universities to help keep U.S. scientists engaged.

Together, we formed the U.S. Academic Alliance for the IPCC.

And a LLM can do an inefficient, noisy job of emulating such a model.

Nonetheless, I do think it would be possible, interesting, a reasonably appropriate use of technology and possibly useful to develop a small language model that can recognize and classify the 277 climate myths indexed at Skeptical Science in a text and link to a scientifically reviewed rebuttal.

I don’t disagree with you - this is a social problem not amenable to technical solution.

Using human intellectual labor to respond to documents indistinguishable from the extrusions of synthetic media machines is not sustainable.

This may well be LLM-generated garbage — certainly, I am pretty sure the authors could have fed a LLM their past writings and asked it to generate a report, and they’d have ended up with something similar.

It is not the way to write a scholarly rebuttal of this report, but were it not being used by the US government for legal purposes, it would not merit such a rebuttal.
