Today, our #SCIMaP team released an impact analysis of the White House proposed FY 2027 NIH and NSF budgets.

Bottom-line: if enacted, cuts to science and medical research would lead to $35B in economic losses and 150,000 lost jobs in communities all across the US.

GFS map of temperature anomalies over the contiguous USA for March 21, 2026.

GFS map of temperature anomalies over the contiguous USA for March 21, 2026.

We need to talk a bit about how utterly absurd the March heatwave was in the USA.

This heatwave would have been impossible without a boost from climate change, but even with climate change it remains a deeply unlikely event.

A thread looking at some of the numbers.

Map showing snow water equivalent percent of the 1991-2020 median for the Western United States on April 10, 2026.

Map showing snow water equivalent percent of the 1991-2020 median for the Western United States on April 10, 2026.

This is a frightening map, especially given the fact that this is normally near the peak in snowpack across the West. There are many far-reaching consequences from this historic snow drought, ranging from increasing risk of summer wildfires to major water concerns.

Be sure to talk to #AGU25 student poster presenters! See someone standing around at their poster, stop and ask them to give you a short overview, and ask a friendly question or two.

It's a good -- and fun & easy -- way to support professional development and skill building in the geosciences. πŸ§‘β€πŸŽ“

Deadly rivers in the sky A new Washington Post investigation reveals where climate change has supercharged the movement of moisture through the skies.

Gift Article!

A great article! Well-researched and written, with an excellent animation that makes climate change and the associated increase in atmospheric water vapor much easier to understand!

"Health losses attributed to anthropogenic climate change," a brief communication in the journal Nature Climate Change. There's a map showing regions of the world, and pie charts of relevant studies as they apply to different health impacts like "heat-related deaths" and "maternal and child health"

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" πŸ”“ www.nature.com/articles/s41...

Updating Mental Models of Risk Disasters are no longer isolated events. This demands a fundamental change in how we think about and respond to complex risk.

To understand modern risk, we have to grapple with emergent and novel aspects of hazard, vulnerability, exposure, and response that comprise risk.

Ice breaking capabilities are essential to support critical research on the Antarctic ice sheet and its response to climate change. This reversal of decades of US leadership in polar research is shortsighted and counterproductive.

Hurricane Erin achieved something most storms do not this weekend. "Extreme Rapid Intensification". Did climate change play a part? Science says, yes.
In 12 hours winds increased by ~65 mph. Only 3 other storms have done that and Erin was the earliest & only August storm to do so.

It is hard to convey in words how lethal the ideology of necropolitics truly is, but the sarcastic, smirking delivery here reinforces that in 2025 we must contend with a political class that publicly delights in human suffering and death.

Graphs showing 25 years of budgets for the National Institute of Health, NASA, and the NSF. In all cases, the proposed budget for next year is far, far below any year of the previous quarter century.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.
