California's drought is caused by changes in wind patterns, not a drop in rainfall.
From the article:
"Their analysis showed that although moisture evaporated from the Pacific Ocean is the major source for California precipitation, the amount of water evaporated did not strongly influence precipitation in California, except in the cases of very heavy flooding. That's because the amount of water evaporated from this ocean region does not change much year by year, researchers found, and did not cause rain to occur more or less often.
"Ocean evaporation has little direct influence on California precipitation because of its relatively weak variability," Wei said."
Get that; evaporation doesn't change much. IF this were caused by Global Warming then we should see increased precipitation as the atmospheric temperatures increased and radiation is held in to reflect back to the ocean. The cornerstone of AGW alarmism is that CO2 traps heat which evaporates more water from the seas which in turn trap more heat. We now learn there is no increase in evaporation.
