It wasnβt until researching this article that I realized quite how bad the Big Beautiful Bill is for clean energy β reduced royalty rates for fossil fuels, a gutting of fuel economy standards, and subsidies for biofuels & coal, along with the IRA cuts we all knew

Things will slow sharply. Federal grants are the biggest source of support for the graduate students and postdocs who are essential to many projects.
02.03.2025 00:29 β π 1 π 0 π¬ 0 π 0Weather and climate data shown on this website and countless others are at risk. The National Oceanic and Atmospheric Administration (NOAA) is the U.S. agency responsible for global weather forecasting, hurricane prediction, ocean observation, and many other services vital to public safety. Its satellites, supercomputers, and research teams provide essential data that help us understand our planet and protect lives. On February 27, the new U.S. administration initiated mass firings at NOAA. These actions are unethical and deeply disruptive to the talented scientists and engineers who dedicate themselves to the public good. The firings, along with expected budget cuts, have serious implications for the availability and quality of weather forecasts produced by the United States. They must be reversed immediately. Much of the data on this website is downloaded directly from NOAA's servers. In this environment of uncertainty, access could be disrupted at any time. While I'll strive to keep all features on this website functional and switch to alternative data sources if necessary, some datasets have no substitute if they go offline. If this concerns you, speak up. Share on social media. And if you're in the U.S., contact your representatives. - Cameron
All websites that depend on NOAA data should display something like this.

I think some people hear βgrantsβ and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service.
βPausingβ grants means people donβt eat.
New by me in @heatmap.news: The LA fires have accelerated the looming financial crisis facing gas utilities from 2035/2040 to today.
Preventing that disastrous cost spiral, though, can help make burned areas safer, easier to rebuild, and more insurable! (1/12)

Devastating for scientists and their research, and everyone who benefits from that research. 
Iβm not sure if everyone outside academia is aware that a delay or βpauseβ in grant funding often means the researchers themselves are lost from the field, along with their expertise.

France has added a 1.6 GW reactor to its grid after 17 yrs building. It will be taken off line shortly for repairs as discussed in the thread. In that time, the US added 191.8 GW of solar. After accounting for capacity factor (~25%) that's still 30x the capacity added. π§ͺππ‘βοΈπ¨π
