So Cal has had erratic weather patterns for as long as they've been keeping records and beyond. Couple that with horrible water management policy and an enormous (and honestly unsustainably large) population, and we end up with the situation we're in now. The fact of the matter is that there already not enough water here, both surface water and ground water, and the sheer amount of people and requirements put a massive burden on the system. This is why LADWP's water wars led to fighting in Owens Valley and why most water has to be imported into the LA basin. And then you have schmucks in the San Joaquin valley constantly trying to take more than their fair share to grow fucking almonds and other bullshit crops that get exported abroad, while charging regular citizens out the ass to take a shower.

Not to say your wrong, but it's disingenuous to ignore the underlying reality and just say climate change. Sure rising temps are a problem, but at this point they're just exacerbating an already problematic system.
