Common Era time-transgressive forcing of Caribbean water balance - Communications Earth & Environment The balance between precipitation and evaporation in the Caribbean region during the Common Era can be estimated through analyses of sedimentary foraminiferal assemblages that record submarine groundw...

Led by Pete van Hengstum (Texas A&M), we have a new article out focusing on water balance ☔️ in the #Caribbean region over the past two millennia (+ implications for future changes under #climatechange), using a coastal Blue Hole in the Bahamas as a natural archive!

Safe travels Dan! And yes, great chat, and appreciate the additional resources you shared.

And, FWIW, I agree with all 4 of your points.

I appreciate the response!

Okay, so do you think SAI is a good idea?

I would argue that part of the larger uncertainties/lower confidence is the lack of observational constraints for SAI. Do you disagree?

What is the evidence the models converge on the hydro response? GLENS seems to suggest they absolutely do not.

1000% agreed. The idea that we have any reasonable confidence in (among other things) the hydrologic cycle response to stratospheric aerosol injection (SAI) is deeply unserious.

Fortunately, last time I expressed my concerns, I was assured that nobody is actually advocating SAI! (lolsob)

How much do you think ocean forcing has contributed? La Nina didn't really kick off til recently.

(love that review article by the way!)

Tehran is having an historic drought due to a combination of factors, including climate change.

The ocean is not helping.

I’m sorry to be self promoting but I a) have never been seduced by a fascist with a brain worm b) am capable of crafting a decent sentence and c) wrote a book that did not earn me a fawning profile in the newspaper but is still pretty good

Irrigation-induced land water depletion aggravated by climate change - Nature Water The rapid expansion of agricultural irrigation raises concerns about exacerbating water scarcity, but land–atmosphere interactions are often overlooked. This study isolates irrigation impacts from oth...

In our new study @natwater.nature.com led by Yi Yao @ethz.ch, we show that irrigation expansion in many regions substantially decreases the net water influx from the atmosphere to land, further aggravating the existing drying trends caused by climate change www.nature.com/articles/s44...

Just published this new paper, with a bunch of fantastic colleagues, with many suggestions for "Improving the representation of plant water stress and water use in Earth System Models." Access is free online. We have some great figures, thanks to Victor Leshyk. 🧪🌐🌳🌎

A new Atmospheric-Rivers Historical Data Record, from @CW3EScripps, is now being hosted by NOAA's NCEI, w/data for analyses like discerning the difference betwn West Coast IVTs strong enough to "look" like ARs that are ARs vs those due to other conditions.

Compounding future escalation of emissions- and irrigation-induced increases in humid-heat stress - Nature Communications This study shows that future exposures to moist-heat increase more rapidly than those to dry-heat, and irrigation can further amplify moist-heat-related health risks. Improving irrigation efficiency a...

Future changes in irrigation will reduce dry-heat stress (without reversing GHG trend) and will substantially amplify moist-heat stress (strengthening GHG trend).

Climate change DEFINITELY affects hurricane:

STRENGTH: Warmer water is hurricane food

RAINFALL: Warm air holds more water vapor

SURGE: Warmer water expands, warmer ice melts, sea levels rise

PREDICTION: hotter seas mean faster intensification

You'd think the Colorado River Basin dispute amounts to conflict between the upper and lower basin states based on most coverage, but Tribes and Mexico also have a big role here. We talked with Cora Tso and Sam Sandoval about these issues on Water Talk
