Increased efficiency of water use does not stimulate tree productivity - Nature Climate Change 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...

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...

I can't access AGU journals either!

Friday AM for me this year!

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!

Interested in how river water changes under climate change + human perturbations?

Come join our diverse group of learners. You will learn and grow to ask questions, +use big data, reactive transport + machine learning models

Wrapping up your PhD? I’m planning to hire a postdoc in the next few months (start date flexible). Will start formally advertising soon, but you heard it here first!! Possible research topics include - critical zone hydrology, agricultural water quality, SW-GW interactions. Reach out if interested!

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.

Musk should be asked about this in every interview he does now and forever. To ignore it is a dereliction of duty.

Looks like something we should defund.

Senator Marsha Blackburn tweets: "We're going to build a big, beautiful Golden Dome."

Am I crazy or did we just have a convo about how we can't fund cancer research?

The real costs of research funding cuts UW–Madison could lose tens of millions of dollars in annual research support due to a proposed change in federal funding. But what’s really at stake? The university’s ability to advance life-saving re

With proposed changes to NIH support, potentially life-saving research at UW–Madison would become slower and less ambitious. And the true cost would fall on those waiting for the next medical breakthrough, who would have to wait even longer.

Might not be fun flying out either! The forecast is not looking great the next 48-72hr.

Oh man, I guess you made it through these storms?

Monstrously destructive, incoherent, ill-informed tariffs based on fabrications, imagined wrongs, discredited theories and ignorance of decades of evidence. And the real tragedy is that they will hurt working Americans more than anyone else.

🚨 #NOAA is essential for weather forecasting, climate research, and public safety.

AGU stands with the scientific community in urging Congress to protect and strengthen NOAA, not dismantle it.

Our economy, environment, and safety depend on it.

I am now seeing what you're seeing.

Ah, I see it now.
