I recently gave a talk on earth science to a group of middle schoolers, and it dawned on me that many of the kids in that age group will be alive to witness what the outcome of Roger Revelle's "great geophysical experiment" looks like in the year 2100.

July 2025 marks the 80th anniversary of the "Endless Frontier" report, which led to the establishment of NSF and transformed the US from a science backwater to a global research powerhouse. Will today's congress sustain or abandon that incredible success story?

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

The President's Budget request as released yesterday will gut scientific research. Why should you care?
1) Science is fundamentally a jobs program. Many 100,000s are employed to do science and work for you, the US taxpayer.

Cutting research at the National Science Foundation by more than half(!) is intentionally sabotaging the future. These are contracts the federal government competitively awards to universities to develop breakthroughs and train graduate students to become future leaders & experts. Future is at risk.

This is not just a NASA thing, and not just an NSF thing, this is an all-of-science thing (also involving our siblings in the humanities). The president's budget shutters everything that _actually_ makes America great.

Please call your Congressfolk and ask them to reject these travesties.

It’s Not Too Late to Save NASA’s Imperiled Search for Alien Life, but the Clock Is Ticking NASA’s astrobiology ambitions are at risk of collapsing under the White House’s proposed budget. But your voice can make a difference

The President's budget request would be devastating to NASA science and our quest for life beyond Earth.

But there's still time to act, and your voice matters.

Trump’s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives U.S. productivity growth — and pays for itself

Investing in basic science more than pays for itself! Cutting NSF and NIH would hurt the US economy. (Now might be a good time to remind your congressional reps about this)

A victory for the federal scientific workforce! We could not stand by while this irreparable harm continues at NSF, NOAA and all our scientific agencies.

PGC provided amazing, unique data and services. We are losing key knowledge and insights without them supporting US and global polar research. Tragic.
