U.S. Droughts Will Be the Worst in 1,000 Years

RATE THIS! +25

Several studies in recent years have predicted that the American Southwest and central Great Plains will experience extensive droughts in the second half of this century, and that advancing climate change will exacerbate those droughts. A new analysis says the drying will be even more extreme than previously predicted, the worst in nearly 1,000 years.

 

Some time between 2050 and 2100, extended drought conditions in both regions will become more severe than the megadroughts of the 12th and 13th centuries. Tree rings and other evidence indicate that those medieval dry periods exceeded anything seen since, across the land we know today as the continental U.S.

 
The analysis “shows how exceptional future droughts will be,” says Benjamin Cook, a research scientist at the NASA Goddard Institute for Space Studies in New York City and lead author of the study. The work was published online today in the inaugural edition of Science Advances and was released simultaneously at the American Association for the Advancement of Science annual meeting here.
 
Cook and his colleagues reached their conclusion by comparing 17 different computer projections of 21st century climate with drought records of the past millennium, notably data in the North American Drought Atlas. (The atlas is based on extensive tree-ring studies conducted by Cook’s father, Edward, a researcher at Columbia University’s Lamont-Doherty Earth Observatory.)
 
The models consistently demonstrated drought worse than at any time during that epoch, and worse than the current drought out West, which has prevailed for 11 of the previous 14 years, according to the U.S. Drought Monitor. In 2014 the drought cost California more than $2 billion in agricultural loses alone, according to the University of California, Davis.

I guess, people will take this analysis and prediction seriously and do something about it - some set of recommendations and organised effort is desperately and quickly needed Reply
