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.”

It can be tough to make sustainable choices, and even harder when sustainable materials don't hold up. Loliware has a solution to the plastic straw problem: its seaweed-based straws are stronger than paper alternatives and once used, can be composted and return to the earth or sea without causing harm. Sea Briganti, CEO of Loliware, joins Closing Bell to discuss the tech behind the straws, new product launches, and more.
Umbilical cord blood banking platform Anja Health raised $4.5 million dollars in a seed round led by Seven Seven Six, a venture capital firm founded by Reddit co-founder Alexis Ohanian. Anja Health offers a personalized, doctor-backed cord blood bank, which lets new parents freeze stem cells from their child's umbilical cord so they can be used to treat diseases in the future. It's a process Anja has called 'Hollywood's best-kept secret,' as celebrities like Kylie Jenner, Serena Williams, and more have all banked their umbilical cord blood. Kathryn Cross, the founder of Anja Health, joins Cheddar News' Closing Bell to discuss.
After learning that the suspect in the Uvalde school shooting posted about his intentions on Facebook, activists are urging social networks to make changes. Lena Derhally, a licensed psychotherapist and author of "The Facebook Narcissist," joined Cheddar News to discuss the role social media plays in school shootings. "They're not really invested in taking down hateful content," she said about social platforms."In regards to the shooting, it was 15 minutes before that actual threat. It would be pretty hard for a social media company to trace that threat that quickly. But what they can do better is take down threats and hateful content much faster and more than they're doing now."
