Temperatures hit 82 degrees in Washington, D.C., Wednesday, one of the highest readings the city has ever experienced in February. And for the second day in a row, Boston set a high-temperature record for a February day: 71 degrees.
In New York’s Central Park, the temperature hit 78 degrees, the highest ever recorded in February. The milestone shattered the record for Feb. 21, which had previously stood at 68 degrees, back in 1930.
“We’re not breaking daily records, we’re breaking all-time temperature records,” said Andrew Freedman, senior science editor of Mashable.
According to Freedman, part of the explanation lies in an unusual disturbance of the polar vortex, which in the past week has split in two, producing two distinct cold waves across the globe.
“You had one portion of it moving into the Western U.S. and Canada, while at the same time one portion of it moved into Europe and Eurasia,” Freedman said. “So those are the two cold spots in the Northern Hemisphere right now. And in the eastern U.S., suddenly we had this incredible warm-up today and on Tuesday.”
Freedman explained the split in the polar vortex. “Normally, you have this circulation of fast winds in the upper levels of the atmosphere over the Arctic. Usually, it stays put; it behaves well.” But this year the planet experienced what Freedman called a Sudden Stratospheric Warming event. “You had energy from the lower atmosphere go up to the upper atmosphere and sort of knocked it off balance.”
Freedman added that climate change is also contributing to the record temperatures on the East Coast. “It’s easier for us to set these high-temperature records as the climate continues to warm,” he said. “That's the bottom line climate message overall.”
And as for what’s ahead, well, Freedman said, on Thursday, “It’s going to snow in Boston.”

NASA is gearing up this week for a mission to launch a SpaceX Falcon 9 rocket into a near-Earth asteroid in an attempt to move it slightly off its projected course. Thomas Zurbuchen, an associate administrator for the NASA Science Mission Directorate, joined Cheddar's "Opening Bell" to provide some additional details about the Double Asteroid Redirection Test (DART) and explained why it is necessary as a means to protect Earth.
With Thanksgiving two days away, the USDA is reminding hosts of the importance of food safety. Karen Hunter, Food Safety Expert, USDA, joined Cheddar's Opening Bell to discuss the best food handling and leftover tips ahead of the holiday.
Jill and Carlo are a bit delayed today on account of Carlo's internet not working. Better late than never, they discuss what we know about the suspect in the Christmas parade crash, closing arguments in the Arbery killing trial, and more.
If you’ve ever watched a show or movie where a character is unconscious for some reason - drowning, electrocution, stabbed in a knife fight - you probably know what to expect next. Some hero will come perform what looks like cardiopulmonary resuscitation (CPR) for a minute or two, perhaps in slow motion, and definitely with a dramatic musical score. And bing, bang, boom, the unconscious character miraculously comes back to life.
If you’ve ever suspected that this is a gross exaggeration of the efficacy of CPR, well, you’re right. But exactly how wrong Hollywood gets CPR is hilarious at best and downright dangerous at worst.
Countries around the world continue to grapple with rising COVID cases, with Germany confirming case numbers at their highest at any point during the pandemic. German officials say that 48,000 new cases are being reported everyday.
Jill and Carlo cover the developing story out of suburban Milwaukee, where a speeding SUV careened through a Christmas parade. Looters get more brazen in San Francisco, the missing Chinese tennis star resurfaces, and more.
A CDC panel has unanimously endorsed boosters of the Pfizer and Moderna COVID-19 vaccines for all adults. Internal medicine physician Dr. Vivek Cherian joined Cheddar News to weigh in.
Neuroscientist Dr. Bankole Johnson joined Cheddar News to talk about the expectation of boosters for all U.S. adults and what the move would mean in the fight against the pandemic.
Deborah Sass, CO-CEO and Founding Partner of Space Hero, joins ChedHER to discuss how she's creating a global competition to send someone on a 10-day trip to space, her experience in the space industry without a background in STEM, and how she hopes to inspire younger generations of women.
