No, this polar vortex doesn't disprove global warming
It's a question on many blue lips this week, as Michigan braces 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.
"Weather is day to day, week to week, and climate is the long-term average of all the weather that occurs over a long period of time, like decades," said David Easterling, a climate scientist with the National Oceanic and Atmospheric Administration's Center for Environmental Information in Asheville, N.C.
"You're always going to have these occasional cold-air outbreaks, but we've been having fewer of them over the last few decades."
