Trump's new executive order "looks like an explicit attempt to destroy peer review for federal science grants,” a physicist in Texas tells @dangaristo.bsky.social. 🧪

www.nature.com/articles/d41...

Trump order gives political appointees vast powers over research grants

Researchers are alarmed that the move might upend a long-standing tradition of peer-review for grants.

Firings are happening right now at the National Science Foundation. Essential staff are being cut.

This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.

Good news! Trump sought to eliminate NOAA's Oceanic and Atmospheric Research (OAR), which would have led to the closure of NOAA Research Labs. Among other important climate research, this would have meant eliminating the Keeling Curve.

The Senate Appropriations Committee said no!

bit.ly/3TShZKk

NOAA OCEANIC AND ATMOSPHERIC RESEARCH
The Committee's recommendation provides $657,053,000 for the Office of Oceanic and Atmospheric Research. OAR programs provide environmental research and technology needed to improve
NOAA weather forecasts, climate predictions, and marine services.
To accomplish these goals, OAR supports a network of scientists in its Federal research laboratories, universities, and joint institutes and partnership programs.
The budget request proposes eliminating OAR, potentially terminating many of its programs and transferring others to operational
NOAA line offices, such as the National Weather Service and NOS While the Committee could be open to realigning some programs to enhance operational outcomes, the absence of detailed plans hinders informed decision-making. Consequently, the Committee maintains funding

I am fairly successful by academic standards. I have a tenure track job, wrote papers, have grant funding, mentor students.

Senate appropriators showed today they are *not* down with Trump's proposed budget cuts for NASA and NSF. (Likely NOAA too, but can't say for 100% yet.)

Long way to go to a law. But this is rare good news for scientists this year.

This IEA graphic shows how global sales of electric vehicles & improved efficiency of combustion vehicles (eg hybrids) is slashing growth in global oil demand. Use in road transport has peaked & likely to soon post annual declines. Aviation & petro-chemical feedstocks only drivers of growth now.🔌💡🔌🚗

IEA data shows global demand growth for oil has been eliminated for road transport and is declining for aviation and shipping and is now negative for other sources. Additional demand growth remains in aviation and as petro-chemical feedstocks.
