Today is the unofficial end of the California rainy season and the last official snowpack survey. There's basically no snow, and the reason is #climatechange.

Extreme heats leaves California mountains in a snow drought

An extremely warm March melted most of the snow in California's Sierra Nevada. The early melt fits a long-term pattern as greenhouse gases push temperatures higher.

Survey from yesterday’s class:
How many think climate change is an existential threat? 100%
How many think climate change is at least partially due to human choice? 100%

As a third generation Californian the writing has been on the wall for how many decades?

The only way our economy understands to deal with water management is to build another megadam someplace.

That might work if the state received the same amount of water annually.

And I guess the alfalfa farmers are still benefiting from their senior water rights to the Colorado and California water.

The thing I worry about as period of unusual climatic stability, fades into the rearview mirror, is how much more likely it will be we get a 1997 event. Historically California is subject to mega floods although I think the last one was in 1870 or something like that. LA got flooded like crazy, but that was really before there were people there.

@GhostOnTheHalfShell @petergleick The "new (not) normal" is wild, unpredictable weather swings.

The new normal is a constantly shifting landscape, not un similar to dunes in a desert

Strangely gripping and unsettling. You can feel how real climate change becomes when the snow just… isn’t there.
