Megadroughts Grow Across The World
“Science” recently published a paper titled “Global increase in the occurrence and impact of multiyear droughts.” Its primary conclusion was “The authors concluded that megadroughts also are increasing in occurrence, frequency, and severity on a global scale, and identified the regions where the vegetation is highly susceptible to these episodes.”
*Droughts Around The Globe
Low precipitation and more evaporation are among the major causes of these megadroughts, each caused by global warming as temperatures rise. According to Popular Mechanics, grassy regions are most likely to suffer, and forests less so.
Southern California
This is another example of how growing droughts affect economies across regions. Some of the Southwest regions of the US are still in what is considered a 1,200-year drought. In California, drought has put almost one million acres out of production. California’s agricultural revenue is $50 billion, employing over 400,000 people.
The U.S. Drought Monitor shows “extreme drought” conditions from southern California through the southern tiers of Arizona and New Mexico. In southwest Texas, the conditions are “exceptional drought,” which is the most dangerous designation. Drought conditions extend as far north as Utah and Nevada.
Australia And Chile
Globally, megadroughts are present in Australia, Chile, and Argentina.
