There's no denying that the earth goes through its natural cycles of warming and cooling, causing extinctions and mass migrations. There's also no denying that the globalized model of economy has negatively terraformed this entire planet in non-sustainable ways toward an ecosystem disaster that will devastate both humans and other living creatures alike.
California's climate change was always inbound. What has severely amplified the problem is industrial agriculture's depletion of the natural aquifers beneath the land that were originally the land's way of replenishing living water supplies during periods of intense draught and scarcity. You can't just keep raping the land of its resources and then complain when there's nothing left. The earth has limited bounty -- when are modern humans going to get it through their thick heads?
The only way to solve the world's ecological problems is to return to the ancestral knowledge of the aboriginals. Before europeans colonized North America, pretty much the entire continent had been terraformed by the natives into sustainable food supplies that worked in tandem with nature's needs as well. There was true stewardship. Right now we are taking everything we can under the profit model with no regard for future generations. We are seeing adults who are basically taking the livelihoods of their own children and grandchildren away from them because the baby boomer generation taught them that making money and living exorbitantly matters more than anything.
The argument about climate change is a bait and switch. Modern humans were destroying this planet well before the AGW started. Get a clue.
I can't imagine one of the very best universities in this Nation that employs Professor Condi Rice putting out "bad" science. For those who have lived through the 40-year drought, the focus needs to be on an interstate-type system of water pipelines to relocate water from floods to droughts .

Calif is a marginal desert that has too high of a population and grows too much food for such an arid region. This drought would be no big deal if not for the artificial burden man puts on the limited water resources.
