“Climate Change is real. California Republicans believe it and are working to address it.”
– John Kasich and Arnold Schwarzenegger
Five years ago the New York Times and Governor Jerry Brown announced the California Permanent Drought.
A few months later, California was deal with historic flooding.
There has been no trend in California precipitation over the last 125 years.
Long term, droughts have become much less common and severe.
Thirty years ago, the New York Times knew that the 20th century was unusually wet in California, and that the Medieval Warm Period was global.
“Lisa J. Graumlich, who examines the ring patterns of foxtail pine trees and western junipers in the Sierra Nevada, has compiled a detailed record of the year-to-year variation in temperature and precipitation over the last thousand years.
She has seen in the North American trees the feathery but unmistakable signatures of the Medieval Warm Period, a era from 1100 to 1375 A.D. when, according to European writers of the time and other sources, the climate was so balmy that wine grapes flourished in Britain and the Vikings farmed the now-frozen expanse of Greenland; and the Little Ice Age, a stretch of abnormally frigid weather lasting roughly from 1450 to 1850. A Crucial Question
“We can now see that these were global climate phenomena, not regional temperature variations,” she said. “The question is, how did we get those warmer temperatures during pre-industrial times, and what can we learn from those conditions about what is going on today?”
Western landscapes in presettlement era were very smoky places.
Sixty years ago, the Squaw Valley Winter Olympics almost had to be cancelled because of a lack of snow.
And in 1932, the Lake Placid Winter Olympics almost had to be cancelled because of a lack of snow.
But no shortage of snow now – we are expecting another couple of feet here in Cheyenne, Wyoming this week.
