The California drought may have put water in short supply, but debate about it is in surplus. Water use has come under even greater scrutiny as Californians struggle to deal with the current and future reality. Groundwater overuse during the drought has reached epic proportions, with the land surface in some locations sinking almost two inches per month as a result. In addition to arguing over how to use the little water they have, people are also debating the question of whether humans are partly to blame not just for water supply issues, but for the drought itself.

..

Late last year, a NOAA report concluded that climate change wasnt required to explain the lack of rainfall, while a separate tree ring study found that the drought looked to be the most severe in 1,200 years. The rains have been fended off by a persistent pattern of high air pressure above the northeastern Pacific that seems to have been a product of ocean surface temperature patterns farther west.

..

But rainfall isnt the only factor that contributes to drought. The heat of the day sucks moisture out of the soil, helped along by blowing winds. Boost either of those factors, and youll need more rainfall to keep the drought account from going in the red. Since the globe is warmer now than it was a century ago and California is part of that globe, its fair to guess that climate change isnt helping.

..

To cut to the heart of the question, a group of researchers led by Lamont-Dohertys Park Williams designed a study to quantify the contribution of global warming to the current drought.

In the end, the researchers calculated that anthropogenic global warming was responsible for 8 to 27 percent of the extremity of the drought between 2012 and 2014, with the dearth of rainfall chipping in around 70 percent. Because of the way they estimated anthropogenic impacts, the researchers say these numbers are conservative estimates.

..

If you think in terms of the probability of a drought this extreme taking place, the anthropogenic contribution is enough to make it about twice as likely. The researchers write that this analysis illustrates the general fact that the anthropogenic drying trend, while still small relative to the range of natural climate variability, has caused previously improbable drought extremes to become substantially more likely.
