NASA On Air: NASA Study Finds Carbon Emissions Could Dramatically Increase Risk Of U.S. Megadroughts (2/12/2015)
LEAD: NASA study finds carbon emissions could dramatically increase risk of U.S. megadroughts.
1. Analysis of current greenhouse gas emission trends indicate that the Southwest and Central Plains have an 80% likelihood of megadroughts between the years 2050 and 2099.
2. This is the first study to compare future drought projections directly to drought records from the last 1000 years.
TAG: The 1930’s Dust Bowl only lasted a decade. These new results indicate future droughts may last at least 30 to 35 years.
