“I think climate change is more complex than global warming will make it hotter,” Guadagnino tweeted to Trump. “It has to do with disruptions of atmospheric conditions, ocean patterns, jet streams and s--t like that.”

The former MTV reality star later responded to Twitter users who mocked him for replying to Trump, asking “why does having a summer shore house automatically make [you] stupid?”

Trump tweeted Thursday evening about the cold weather blasting much of the U.S., saying the country needed “a little bit of that good old Global Warming.” 

Large swaths of the US are expected to see record-breaking cold temperatures over New Year’s weekend, with some areas expected to have low temperatures in the negative 40s.

Much of the Northeast is also facing wind chill advisories over the weekend, with wind chills in New England expected to measure between 20 and 40 degrees below zero.
