@Quantamagazine article on mixing changes in deep temperate lakes and some ecological impacts (e.g. deoxygenation), today. Why? Sudeep Chandra documented stratification increases (less mixing) in 84% of 189 lakes globally. Some lakes stopped mixing altogether.

Study of ~23K human-wildlife conflict reports in California (2017-2023) shows prolonged precip drought is associated with increased overall conflict occurrences across taxa and is especially associated with increased conflict w/carnivore species.

Axios highlights this graphic from International Energy Agency today. Despite current “failures to launch”, the last decade has seen (~14%) progress on emissions-reductions front globally that would payoff (some) in the long run, but actual reversals must be prevented.

Although we've another rainy rainy atmospheric-river landfall in the works on the West Coast, I guess its time again to remind you of the snow-v-rain point-and-click forecast map that @CW3EScripps offers so you can see what's predicted for your neck of the woods...

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.

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
