Antimony is important test of whether U.S. can restore supply chains from shutdown caused by Trump tariffs at a time when production dwindled in giant Chinese mine & when China is dominant (60% of world supplies). Antimony is used to harden armaments etc & now scarce.

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.

FIRO is already being similarly evaluated in depth at half a dozen other reservoir systems along the West Coast, and the USACE is preliminarily triaging the efficacy of the policy at hundreds of other reservoirs nationally. 7/7

Lake Mendocino is the 1st reservoir in the Nation to get permission to adopt FIRO. The WCM gives dam operators permissions to store more water, or release more water, than under historical "only water on the ground" rules, based on modern storm/flood forecasts. 2/7

Trump firings at DOE last week were in Offices of Energy Efficiency & Renewable Energy, Clean Energy Demonstrations, State & Community Energy, & Minority Economic Impact. Apparently they’re examples of “Democrat programs” he’s told us he‘d kill during this shutdown.

Model analysis of Greenland ice sheet variations during last interglacial (126K-119Ky BP) indicates atmospheric rivers in Arctic were tied to orbital factors, & that past-future Greenland ice sheet mass strongly related to Arctic AR seasonality.

California hasnt had to issue an emergency plea for public power conservation since 2022, due to a >30x surge in battery storage in past 5 yrs. Contrary to certain ignorant naysayers, batteries keep the grid running even when solar power sources are temp interrupted.

Well, the NWS forecast some "winter-like weather" in the eastern Sierra and surely delivered. Gorgeous in the range today! (Hope Valley, West Fork Carson River, 7000+ feet elevation) Not sure how long the snow will last but its brilliant today.

For an (ancient) larger scale context, back in 2008, it was noted that—after the Western mountain snowpacks—the sloppy snows in the NE could be expected to be next most vulnerable to warming. ->Map of historically how much of precip that fell would have been above freezing if 2C warming applied.
