This time it's not so much that Anthony Watts of WUWT doubts the findings (the word "claim" doesn't appear in the headline), it's that he is amused by the notion that there's yet another pressure on water availability in his part of the USA. Yes, he thinks it's humorous. (Archived here.)
A new paper was reported in a press release from UC Irvine, which said in part:
Freshwater runoff from the Sierra Nevada may decrease by as much as one-quarter by 2100 due to climate warming on the high slopes, according to scientists at UC Irvine and UC Merced.
Accelerated plant growth at higher elevations caused by increasing temperatures would trigger more water absorption and evaporation, accounting for the projected runoff declines, the researchers add.
A diminished river flow will only add to the burden of providing resources to the thirsty farms and homes that rely on it. The state is currently experiencing a severe drought, and some reservoirs and groundwater levels are at all-time lows.
The study findings appear this week in the early online edition of Proceedings of the National Academy of Sciences.
You can read the full press release here. The research was done by Michael L. Goulden and Roger C. Bales. I couldn't find the study at PNAS early edition. I expect it will be posted online shortly.
At WUWT the paper was treated with a mix of disdain, disinterest, disbelief from commenters, and "amusement" from Anthony Watts himself. He wrote:
From the University of California – Irvine and the “Environmentalists are never happy” department comes this amusing quandary.
The cause? Increased high-elevation plant growth fueled by climate warming
I don't think too many people in California and neighbouring states would be amused. California is suffering extreme drought at the moment, according to the US Drought Monitor:
