Study shows how global warming lead to a semi-permanent drought by mid-century
FRISCO — California’s crippling drought may be the new norm, according to scientists who studied the link between greenhouse gases, rising temperatures and multi-year period of record warmth and dryness.
The new study by Stanford researchers found that the worst droughts in California have historically occurred when conditions were both dry and warm, and that global warming is increasing the probability that dry and warm years will coincide.
The findings suggest that California could be entering an era when nearly every year that has low precipitation also has temperatures similar to or higher than 2013-2014, when the statewide average annual temperature was the warmest on record. The study was published in the March 2 issue of the journal of the Proceedings of the National Academy of Sciences.
