As a region, the ten states in the southwestern United States have experienced the worst drought in 1,200 years in recent years. This is the conclusion of a new study conducted by researchers from Columbia University, UCLA, and NASA, the results of which were published in the scientific journal. The nature of climate change have been posted.
The southwestern United States includes California, Oregon, and parts of Colorado, where intense wildfires have raged in recent years.
This is called a “mega drought” that will last at least twenty years. There hasn’t been such a massive, severe drought since the 800’s, the researchers write, who say climate change is a major cause of the drought.
“The past 22 years have been the driest period in 300 years without climate change,” said lead researcher Park Williams of the University of California, Los Angeles. Researchers have estimated that human-induced climate change is responsible for 42 percent of droughts in the region since 2000.
