Maybe understanding soil moisture isn’t as complicated as we thought. New #AGUPubs research by Tara Gallagher & @kaighin.bsky.social

eos.org/research-spo...

New paper: a radically simple theory for soil moisture, that explains much of the large-scale spatial and temporal variability relevant to climate. Surprisingly, VPD and plant physiology are not very important for understanding changes with warming.

Removing Atmospheric Carbon Dioxide Using Large Land Or Ocean Areas Will Change Earth Albedo And Force Climate When large surface areas of the Earth are altered, radiative forcing due to changes in surface reflectance can drive climate change. Yet to achieve the necessary scale to remove the substantial amount...

Vegetation Greening Mitigates the Impacts of Increasing Extreme Rainfall on Runoff Events The number and magnitude of extreme rainfall events are projected to increase throughout the global land surface Projected declines in event-based runoff ratio are found for a majority of the glo...

Really interesting work here from @dficklin.bsky.social and a stellar cast of coauthors: 'Vegetation Greening Mitigates the Impacts of Increasing Extreme Rainfall on Runoff Events' agupubs.onlinelibrary.wiley.com/doi/full/10....

New preprint-> @czarakas.bsky.social shows that land-atm feedbacks occur in wet places! The "classic" view is soil moisture and precip can be correlated in dry-ish regions. We find a bigger role of the atm in wet places, where ET is dampened by lower evap demand. essopenarchive.org/doi/full/10....

Weatherwatch: why cooling white roofs cause neighbours to swelter Climate hack used to reflect heat results in less rain and higher temperatures in surrounding regions, study finds

New piece in the @theguardian.com covering our recent paper on unintended heating caused by painting surfaces white.

Seemingly Simple Climate Adaptation Strategy Could Backfire - Eos Reflecting sunlight can protect a neighborhood from scorching temperatures, but surrounding neighborhoods could suffer as a result.

This work was summarized in Eos as a Research Highlight: eos.org/research-spo...

New paper: painting neighborhoods white is one way to offset warming from climate change. But, we show that doing this perversely causes temperatures to INCREASE in surrounding neighborhoods, due to unintended impacts on rainfall. This increases heat inequality.

one of my Twitter bangers from 2021, reproduced here, with minor editing:

I've been collecting "lessons I've learned communicating climate on Twitter" over the last 8 years and finally thought I'd write a 🧵. This is mainly aimed at younger scientists, but others might find it useful.

The poorly‐explored stomatal response to temperature at constant evaporative demand The direct response of stomata to temperature (the response when evaporative demand is held constant by adjusting ambient humidity) is very poorly known. This review summarises the current state of k...

Our review of the direct response of stomata to temperature just came out in an issue (OK, it was 3 months ago but I just noticed).

We cover what (little) is known, & possible mechanisms and implications.

Several more papers in the works. Watch this space!

I'm giving a virtual talk today (November 18) at 2 pm ET. All welcome. It's on a simple theory for near-surface relative humidity over land. Among other things, the theory has major implications for projected changes in aridity with warming.

New paper: Why is relative humidity high in some places, and low in others? Surprisingly, there is no simple answer to this question, at least for the part of the atmosphere that we live in (near the land surface). We provide one.
