Cold snap shows U.S. could use a bit of 'good old global warming,' Trump says

 President Trump is not buying this whole global warming thing. 
 
 All the proof the president needs that the planet isn't getting hotter is the cold snap hitting the East Coast, which is supposed to stick around into the new year. 
 
 "In the East, it could be the COLDEST New Year’s Eve on record," Trump tweeted Thursday night. "Perhaps we could use a little bit of that good old Global Warming that our Country, but not other countries, was going to pay TRILLIONS OF DOLLARS to protect against. Bundle up!"

 Trump — who once tweeted that climate change was made up by the Chinese to hurt American businesses — was apparently being facetious when he suggested we could use some "good old global warming." 
 
 Trump made a similar comment in 2011 when he tweeted, "So much for global warming" after an October snow in New York. 
 
 It snowed over 4 inches this past weekend in New York City. It is still October. So much for Global Warming. — Donald J. Trump (@realDonaldTrump) November 1, 2011 
 
 The "trillions of dollars" Trump mentioned in Thursday's tweet was a reference to his decision not to be a part of the Paris climate agreement, which aims to combat global warming. Trump's decision makes the U.S. the only country on Earth that has not joined the agreement.

 Trump is far from the first person to argue that winter disproves climate change. In 2015, Sen. James Inhofe, R-Okla., brought a snowball on to the Senate floor to demonstrate that it was still cold outside, thus, he presumed, proving that climate change is not real. 
 
 But scientists are quick to point out that your local weather is not the same thing as climate change. 
 
 "Climate change will not occur evenly from place-to-place. While your backyard may be having an intense cold snap, others may be having unseasonably warm temperatures. Climate is all about long-term trends," Zack Labe, a doctoral candidate studying Earth systems science at the University of California, Irvine. 
 
 The cold snap is bringing record-low temperatures to much of the country but 2017 is still on track to be second- or third-hottest year on record, and scientists agree that is due to climate change.

– With bitterly cold temperatures gripping much of the US, President Trump has returned to a familiar theme: Mocking global warming. "In the East, it could be the COLDEST New Year’s Eve on record," Trump tweeted Thursday. "Perhaps we could use a little bit of that good old Global Warming that our Country, but not other countries, was going to pay TRILLIONS OF DOLLARS to protect against. Bundle up!" This is the first time he has tweeted about the subject as president, though he has made dozens of similar remarks when the temperature has dipped in previous years, including in October 2015, when he tweeted: "It's really cold outside, they are calling it a major freeze ... Man, we could use a big fat dose of global warming!" Some reactions: Long-term trends. Scientists once again pointed out that weather and climate are not the same thing—and 2017 is still expected to be one of the hottest years on record. "Climate change will not occur evenly from place-to-place. While your backyard may be having an intense cold snap, others may be having unseasonably warm temperatures," Zack Labe at the University of California, Irvine, tells USA Today. "Climate is all about long-term trends."
