Western American Mega-Drought Ahead


A new study provides evidence for an American mega-drought.

We are talking about extreme drought conditions that will extend from the Mississippi River to California that will last for thirty, forty or more years, literally leave our highly populated, water dependent society in uncharted territory, threatening our civilization's ability to adapt to what will be  a radically altered future environmen
Imagine what the water situation will look like in 2075?  Depleted groundwater, decimated agriculture, irreparable damage to ecological habitat. Think apocalypse.”

Alaska crushes record for hottest December as Arctic sea ice hits record low In its hottest December ever recorded, Alaska was a stunning 15.7°F above the 20th century average. And the year ended with Arctic sea ice hitting an all-time record low. While the East Coast had a cool December and New Year’s week, Alaska baked. Last Tuesday, Anchorage hit 48°F , warmer than southern cities from Atlanta and Jacksonville to Houston and New Orleans. The National Oceanic and Atmospheric Administration (NOAA) reported this week that Alaska averaged 19.4°F for the month, topping the previous record (1985) by a whopping 2.1°F. “That’s really quite astonishing,” said Rick Thoman, the National Weather Service’s climate sciences and services manager for the Alaska region. As he explained to the Anchorage Daily News , “Usually you’re breaking those by a tenth of a degree or two-tenths of a degree.” The Arctic as a whole was so warm in December that Arctic sea ice set a new end-of-year record lo

I went to a presentation at the University of Washington by Professor Raftery of the Statistics and Sociology Departments of a recent paper of his and colleagues (Alec Zimmer, Dargan M.W. Frierson, Richard Startz, and Peiran Liu) in the Journal Nature, entitled Less than 2 °C warming by 2100 unlikely   (link behind a paywall) . Their paper is a response to a need to provide a statistical forecast for global temperatures.  What the IPCC has previously provided are "scenarios" based on "expert" thinking.  Raftery has previously developed statistical methods for estimating world-wide migration patterns that has been adopted by the United Nations.  At the presentation he presented a statistical model for forecasting global temperatures. Their result is a 90% interval forecast of 2 to 4.9 degrees Centigrade with a median of 3.2 degrees. Their backtesting strongly supported the median.  He also  said " that the data suggested that future improvements in ca
