Study: Extreme Summer Weather Will Become More Frequent
LONDON (CBS DC) – Get ready to face deadlier storms and even dryer summers. That’s the warning from a new report on climate change, reports The Independent.
Researchers at the Potsdam Institute for Climate Impact Research say extreme weather has become more frequent in the northern hemisphere because a warming world traps the weather in the same place.
“Weather extremes in the summer, such as a record heatwave in the United States that hit corn farmers and worsened wildfires in 2012, have reached an exceptional number in the last 10 years,” said the researchers
Changing temperatures can cause changes to the jet stream, which in turn can disrupt weather patterns across the Arctic.
“In periods with extreme weather, some of these waves become virtually stalled and greatly amplified,” it said. “While a few days have little impact, effects on people and ecosystems can be severe when these periods are prolonged.”
These disruptions in the jet stream and cold air from the thawing of Arctic ice may explain why weather systems are stalling.
“We are warming our atmosphere by emitting carbon dioxide from fossil fuels, but the increase in devastating heatwaves in regions like Europe or the U.S. seems disproportionate,” lead author Dim Coumou said in a statement.
The study is published in the journal Proceedings of the National Academy of Sciences.
