High of 79 today, 81 tomorrow. California's had the warmest winter in its record. As evidence of global climate change goes it's pretty weak - a tiny piece of the planet and a relatively short time period - although it still beats the "hey why's it snowing in February" argument that denialists toss out.
The main point though isn't a tedious argument about detection but whether climate change has made our historic drought worse. Warmer weather during the drought means more evaporation and transpiration, only some of which precipitates back. If Gort could be bothered to push the button and remove all excess GHGs from the atmosphere, the temps would drop slightly and we'd be slightly better off.
I've been pretty silent on our local water district and the drought lately, but we've been busy, very busy. I even had the chance to represent the district and meet Secretary of the Interior Sally Jewell to discuss it (and then stopped to talk with the protestors outside who hate the Bay-Delta tunnel proposal).
Our problem is that after the last big drought that ended in 1992 we've stored an additional year's worth of water outside the county in Central Valley, but we can't get it. The water's stored in south Central Valley - it flows downhill there from the Sacramento Bay Delta. The plan never was to withdraw those specific water molecules - instead, we'd take water deliveries they'd otherwise receive from the Bay Delta, and they'd use the water we stored there instead. Now, for the first time in the 54-year history of the State Water Project, they're planning zero water deliveries, so we can't make this trade. The federal system operated by the Secretary of the Interior is still running somewhat, so maybe we can make it work.
Meanwhile we're calling for a 20% reduction in water use locally. That will still eat into our storage but still leave a fair amount stored in case next winter is also bad. I've been arguing that we should use this as opportunity to be in better shape for next time - massively increase conservation, recognize that lawns are like junk food (okay in small quantities only), and to tap into the massive river that is wastewater and start direct potable reuse of that water, just like they do on the Space Station. We'll see what happens!
