Thinking of the John Holdren quote that we have three options: mitigation, adaptation or suffering. The third is growing ever more apparent as progress lags on one and two.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

As a grant writer for environmental causes, I’ve seen first-hand how funding for the environment often takes a backseat to medical research and human services. This article helps demonstrate why this is a problem; the environment is a HUGE influence on public health and quality of life.

This great thread makes a point I've been trying to convey for years. Calling all data-driven prediction or decision software "AI" is a huge gift to LLM hypemen, who want people to believe, incorrectly, that LLM data centers are crucial for solar forecasting or operating buildings and power grids.
Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪
