A new study links the buildup of greenhouse gas emissions to more frequent heat waves, floods and droughts in the Northern Hemisphere.
Greenhouse gases are increasingly disrupting the jet stream, a powerful river of winds that steers weather systems in the Northern Hemisphere. That’s causing more frequent summer droughts, floods and wildfires, a new study says.
The findings suggest that summers like 2018, when the jet stream drove extreme weather on an unprecedented scale across the Northern Hemisphere, will be 50 percent more frequent by the end of the century if emissions of carbon dioxide and other climate pollutants from industry, agriculture and the burning of fossil fuels continue at a high rate.
