Climate change is understood (for a long time now) to create more intense rainfall events which in many places will also be interspersed by more frequent droughts also --
both.
So, what's happened in California has been in keeping with what the modeling generally expects -- more drought, interrupted by bigger rainfall events. Basically that both droughts and flooding become worse:
both.
California is by far the biggest agricultural state.
It's a concerning pattern in most states to have more droughts and floods instead of more frequent smaller rains of the past... Agricultural production mostly depends on having enough rain in a given year, not years apart.
In California, agriculture has been relying on
huge water extraction from a giant aquifer, and that aquifer was getting lower and lower before the big rains of this year.
This was the situation already!:
So, it will be a very large interest to see whether these great participation events (which climate change generally predicted) will result in the aquifer lifespan increasing significantly....
