Here in California, the lack of precipitation during this year’s fall-winter rainy season is already prompting worries of another terrible drought. So Tuesday’s headlines warning about climate change in the polar region leading to endemic drought in California were chilling.
The Los Angeles Times had a well illustrated front-page article.
Last year’s rains were huge and saved the state from disaster. But a future of no rain is frightening because history has shown that long-term drought is a civilization killer.

If the science is correct, then continuing to grow California’s population via immigration and open borders seems unwise, since a desert state cannot support the water requirements for 40 million residents already here. I tend to be skeptical about climate change generally, but a reduction in polar ice can’t be good.
Governor Jerry Brown believes in climate change very strongly, as he shows by traveling around the world giving speeches about it. Yet he has welcomed an unlimited number of Mexican illegal aliens to come here, and he recently signed a bill making California a sanctuary state which is another kind of invitation.
Yet the governor imagines himself to be an environmentalist, despite his active promotion of overpopulation in a state that continues to face a threat to its most basic and important natural resource — water. Democrats are well known hypocrites, but Brown is over the top here.
Climate scientists see alarming new threat to California, Los Angeles Times, December 5, 2017California could be hit with significantly more dangerous and more frequent droughts in the near future as changes in weather patterns triggered by global warming block rainfall from reaching the state, according to new research led by scientists at Lawrence Livermore National Laboratory.
Using complex new modeling, the scientists have found that rapidly melting Arctic sea ice now threatens to diminish precipitation over California by as much as 15% within 20 to 30 years. Such a change would have profound economic impacts in a state where the most recent drought drained several billion dollars out of the economy, severely stressed infrastructure and highlighted how even the state most proactively confronting global warming is not prepared for its fallout.
The latest study adds a worrying dimension to the challenge California is already facing in adapting to climate change, and shifts focus to melting polar ice that only recently has been discovered to have such a direct, potentially dramatic impact on the West Coast. While climate scientists generally agree that the increased temperatures already resulting from climate change have seriously exacerbated drought in California, there has been debate over whether global warming would affect the amount of precipitation that comes to California.
The study, published Tuesday in the journal Nature Communications, provides compelling evidence that it would. The model the scientists used homed in on the link between the disappearance of sea ice in the Arctic and the buildup of high ridges of atmospheric pressure over the Pacific Ocean. Those ridges push winter storms away from the state, causing drought.
