Scientist Warns of Megadroughts That Could Collapse Entire Civilizations
“I find it very concerning to see that human-caused climate change is amplifying the severity of megadroughts.”
A huge region of water in the south Pacific Ocean has reached considerably warmer temperatures than the water around it — triggering a chain of events that’s led to a decade-long megadrought in Chile.
The so-called “Southern Blob” is linked to changing wind patterns and rising temperatures caused by rampant burning of fossil fuels and, as a result, has lasted years longer than a naturally occurring blob would have, according to research published in the Journal of Climate on Thursday. And experts warned Reuters that the severe megadrought it’s causing in Chile is the sort that could even bring down entire civilizations. In fact, they say, that’s already happened in human history.
