From #heatwaves to #floods and #droughts, swings between climate extremes are becoming more frequent and consequential. Researchers are investigating #HydrologicWhiplash and its impacts. Read the PNAS Core Concept explainer: ow.ly/EKaV50ZcVPs #ClimateChange
Low water levels in Lake Shasta, California’s largest reservoir, can threaten irrigation for agriculture, water for hydropower, and boating and fishing.

Some exciting news to share: very soon, NOAA Research will be hiring new federal employees into science positions across the agency! A couple of notes: 1) They will only be open on USAJobs for seven days. 2) Multiple positions at different sites may be in one posting. (1/2)

Just now getting around to posting about this. Nice to be part of this study with Quan Zhang and a host of others! We find that the water use efficiency from increased CO2 does not lead to higher tree growth. You can find the study here: www.nature.com/articles/s41...

The authors theoretically delineate the maximal increases in tree growth that can be expected from increases in plant intrinsic water-use efficiency, which increases with rising CO2. They highlight en...

Do heat waves happen in rivers? How do river heat waves (RHW) compare to air heat waves (AHW)? www.pnas.org/doi/10.1073/... Here we show: 1) RHWs occur less frequently & intensively but last twice as long as AHWs; 2) RHW have risen much faster than AHWs. Congrats to Dr. Kayal Sadayappan!

Musk should be asked about this in every interview he does now and forever. To ignore it is a dereliction of duty. www.nytimes.com/2025/05/30/o...
There is one place, however, where Musk, with the help of his minions, achieved his goals. He did indeed shred U.S.A.I.D. Though a rump operation is now operating inside the State Department, the administration says that it has terminated more than 80 percent of U.S.A.I.D. grants. Brooke Nichols, an associate professor of global health at Boston University, has estimated that these cuts have already resulted in about 300,000 deaths, most of them of children, and will most likely lead to significantly more by the end of the year. That is what Musk’s foray into politics accomplished.

From NSF EAR program director Raleigh Martin on LinkedIn #climatesky #greensky
Yesterday, my federal agency (NSF) experienced a sudden and mass firing of over 10% of our workforce. My own Division lost 20% of its staff. In the blink of an eye, we lost many brilliant scientists, dedicated civil servants, and parents/spouses/caregivers who no longer have a paycheck. The firing was completely arbitrary, with no actual plan to achieve "efficiency" but instead just picking off anyone with the fewest job protections. I grieve for my former colleagues and extend my hand to be of help however I can.

I still have a job - not based on my abilities but simply because my status makes me harder to fire. But who knows what comes next. I'm hoping this assault on science and government is just a passing storm, but even then the damage has already been devastating - careers broken, research disrupted, and resources wasted.

Science is the goose that lays golden eggs - unleashing human ingenuity and systematic thinking toward discoveries that transform our society for the better. Public science funding creates space for research that may not have immediate applications but will yield dividends down the road. Unfortunately, right now the science goose is being strangled and those golden eggs are being lost. Our society will be poorer, sicker, and weaker as a result.
