1. After getting some further insight into changes at NSF (thanks to those who reached out), I deleted a previous post where I tried to make sense of Cheatham's memo as reported in the Science story below.

Kriddie, after defending over a week ago, has a new paper out in WRR: "Carbon Emissions From Low-Order Streams in a Tropical, High-Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology". Check it out! agupubs.onlinelibrary.wiley.com/doi/full/10....

Today was the first field day in my ERC ARIMETH project! I installed a oxygen and water level sensor in Krycklan. It was a great field day, wearing t-shirt, sunny... But this is so wrong. Mid-april in northern Sweden means a thick snow cover, but this has been an abnormally warm and dry winter.

I had the pleasure to follow along Kriddie's PhD from the distance, and her work on carbon cycling in high altitude tropical streams. Now she's Dr. Kriddie!

Looking the get the most out of your stream CO2 data? Check out the coupled O2-CO2 model developed by Jake Diamond and me, out today in JGRB! The model extends the single-station O2 model by coupling DIC mass balance and carbonate buffering. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

This is not business as usual. It’s not just a change in funding priorities going forward; it is the reneging on funding agreements and is profoundly disruptive for even those grants that will be found to be compliant. Meanwhile, trainees who often live paycheck to paycheck are going unpaid.

My drawing below illustrates the importance of spatial ecology for stability: if we ignore space, it's like everyone dancing on the tip of a pin. When space is included (and complex dynamics, too), diversity is easily sustained.

There are about 27,000 scientists at #AGU24, and about half of them work on climate one way or another. Whenever I walk into a room like this, I always take a moment to take it all in—all these people dedicated their lives to working on some of our toughest problems. That gives me strength.
