Despite what Trump says, the polar vortex doesn’t mean global warming isn’t real.
Millions of people in the U.S. are expected to face wind chill temperatures as low as negative sixty degrees when a weather phenomenon known as the polar vortex swoops through the Midwest between January 30 and January 31.
Trump used the weather forecast to try and disprove global warming.
“In the beautiful Midwest, windchill temperatures are reaching 60 degrees, the coldest ever recorded. In coming days, expected to get even colder. People can’t last outside even for minutes,” he stated on Twitter. “What the hell is going on with Global Warming Please come back fast, we need you!”
However, weather and climate are two different things. Weather refers to day-to-day variations in the atmosphere, whereas climate refers to the average weather of a place over a long period of time. So while it’s about to get extremely cold in the Midwest, the world on January 28 was, overall, 0.7 degrees warmer than the average temperature between 1979 to 2000.
Some studies also say that global warming could cause these extreme cold weather events. The studies suggest that as the Arctic warms, the polar vortex, which normally sits on top of the Northern Hemisphere, splits into different pieces and brings cold air southwards. But the science isn’t completely settled and more research needs to be done.
