We are so excited to share the results of this work! Annalise Guthrie’s hard work demonstrates how the loss and regeneration of deep roots can change the way deep soils are structured at a continental scale. This was such a joy to work on! @agu.org

Deep Root Loss and Regeneration in the Anthropocene Drive Continental‐Scale Changes in Deep Soil Structure

Deep root dynamics imposed by land-use change are modifying deep soil structure at the continental scale well below zones of tillage As deep roots disappear, structural unit size increases and ro...

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry

The announcement comes months later than usual, leaving many would-be applicants stranded

Rivers are heating up faster than the air − that’s a problem for aquatic life and people

River heat waves are rising faster than the pace of air heat waves. That’s a problem for fish, drinking water quality, and food and energy production.

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!

Do forest recovery + higher soil organic C elevate production of dissolved inorganic C? No, because cooling soils + lower moisture reduce soil respiration.

On the other hand, drier climate does diminish carbonate weathering + reduce DIC export

With emissions still rising 📈 and the catastrophic consequences 🔥 becoming ever clearer, geoengineering is getting ever more tempting 🧪

But a review has concluded that the main methods proposed to save polar ice 🧊 are not doable or won't work

Geoengineering is not going to save the poles from climate change

A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both
