It's a question on many blue lips this week, as the Midwest braced for below-zero temperatures for its daily high on Wednesday: How can global warming be true when it's so cold?
Even President Donald Trump, in a tweet late Tuesday, seemed to question the coexistence of climate change and an arctic chill over much of the U.S.
“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 Waming? Please come back fast, we need you!,” Trump tweeted.
As climate scientists constantly stress, weather does not equal climate.
