An blast of ice-cold wind and snow is slamming the Midwest. Some forecasts show parts of Illinois and Minnesota could reach a wind chill of -60 degrees Fahrenheit — as cold as Antarctica. And businesses and schools are shutting down as the weather poses a hazard to human life.

And President Donald Trump decided to use this moment to deny climate change:

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! — Donald J. Trump (@realDonaldTrump) January 29, 2019

Once again, Trump is confusing weather with climate — the temperature outside in a given place at a given time says nothing about global temperature trends. In fact, cold snaps like this are predicted to get more common as the planet gets warmer, because the energy loss from melting Arctic sea ice disrupts the “polar vortex” that traps cold air at the North Pole, allowing freezing winds to migrate to lower latitudes. None of this, however, seems to be reaching the same man who once called global warming a hoax by the Chinese.

Social media was quick to leap on Trump’s latest show of ignorance:

If you cared about facts, you would know that climate change doesn’t only cause temperatures to increase. Climate change causes both cold and hot extremes. — Ed Krassenstein (@EdKrassen) January 29, 2019

Weather is not the same as cl– actually, no, we’re not going to waste our breath on an anti-scientific President. If anybody DOES wonder about the apparent contrast between global warming and freezing winter cold snaps, here’s a great article:https://t.co/ln2vaGizl0 — People of Reason and Progress (@TheOfficialPORP) January 29, 2019

Stop asking Betsy DeVos to explain climate change to you. — Kristina Womp-Wong ❄️ (@mskristinawong) January 29, 2019

It wasn’t even that long ago when Trump claimed that climate change didn’t exist because it was cold outside in Washington, DC. There is a huge difference between weather and climate that Trump just doesnt understand or intentionally misleads people. https://t.co/qmq8QBK42t — Eugene Gu, MD (@eugenegu) January 29, 2019

You should get one of these. It helps you control the global warming in your house and it works with WiFi. pic.twitter.com/qDt4UlU9Mw — Gavin Free (@GavinFree) January 29, 2019
