 How strong is the link between global warming and California drought?

Easy answer:  No link at all. For a start, drought is a normal occurrence in California.  Second, since there has been no global warming for 18 years, it cannot  be influencing anything.  Things that don't exist don't have effects.  None of that is confronted by the lamebrain below.  He just regurgitates the usual data-free Leftist propaganda.  And thirdly, there is no significant drought.  Releasing dam water to flow straight out to sea for various crazy Greenie reasons is why there is a shortage of water for homes and crops

Further studies are being conducted at this moment to explore the contributions of particulars to the climate variability which brought about the drought and temperature components related with anthropogenic warming. Thus, when rainfall declined in 2012, the air sucked already scant moisture from soil, trees and crops harder than ever.

The climatic change and its effects may be experienced globally and warmer air and weather are not the only ones to blame since other factors such as evaporation rates and precipitation form part of the main contributors.

If human-caused greenhouse gas emissions were not trapping heat, leading to climate change, the state’s drought could be up to 27 percent less severe than it is, the study researchers say.

Yes, global warming is more than three times higher than natural climate changes and this is bad for California.

The study, authored by five researchers from Columbia University’s Lamont-Doherty Earth Observatory and one from the University of Idaho’s geography department, said if this trend continues then the state will experience more “persistent aridity” within a few decades, according to an August 20 press release from Columbia.

It’s very clear the warming of California has increased the probability of conditions that create drought.

Unlike the natural variation in climate which produces extreme conditions only occasionally, the demand of additional moisture on account of global warming is on the rise every year with concentration of carbon dioxide in the atmosphere rising higher consistently.

The study, said that average California temperatures have increased 2.5 degrees Fahrenheit over the past 113 years. Because of global warming Californian mountain snows have started melting in an accelerated way as well, whereas 10 years ago the melting was dispersed more gradually in time and has helped freshening up the lowlands during the hot season. The monthly changes were simulated in the quantity of water in each bucket between 1901 and 2014. It was found that global warming has contributed between 8 and 27% to the severity of 2012-2014 California drought. Due to the growing global temperature, this fact is turning out to be true for most places worldwide. This means that by around the 2060s, more or less permanent drought will set in, interrupted only by the rainiest years. If California finds itself struggling with this drought, serious planning needs to take place in order to be resilient to a future where it’s increasingly likely that the current drought will look like child’s play.
