No, the polar vortex 2019 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 -60°F when a weather phenomenon known as the polar vortex swoops through the Midwest between Jan 30 and Jan 31. Pres. Trump used the weather forecast to try and disprove global warming.

Trump tweets: 'In the beautiful Midwest, windchill temperatures are reaching minus 60 degrees, the coldest ever recorded. In coming days, expected to get even colder. People can’t last outside even for minutes. 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 Jan 28 was, overall, 0.7°F warmer than the average temperature between 1979 to 2000. Additionally, the 20 warmest years on record occurred in the last 22 years and the last 4 years were the 4 warmest.

In fact, some studies say 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 N. Hemisphere, splits into different pieces and brings cold air southward. But the science isn’t completely settled and more research needs to be done.

One thing that is settled? Global warming is happening, regardless of what the president tweets.
