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.

This summer I got the chance to visit the home town of Eunice Newton Foote, the 19th century inventor and scientist who first noted the heat-trapping property of CO2, and who was also a key player in the US women’s rights movement:

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.
I don't think anyone outside of universities, pharma and biotech, independent research institutions have any idea of what is happening right now. If you haven't sounded the alarm among your friends, family and colleagues, now is the time to do it.

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.
