As the world warms, freezing rain shifts to the U.S. South
By Hannah Richter , Science. Excerpt: Over the weekend of 24–25 January, a major winter storm blanketed the eastern United States in soft snow. ...in many places, the powder gave way to freezing rain, glazing trees and roads in heavy, dangerous ice, bringing down power lines, and depriving 1 million people of light and heat. Freezing rain is a stealth winter hazard, says Zong-Liang Yang, an earth systems scientist at the University of Texas at Austin. ...“...[freezing rain is] relatively understudied.” ...a handful of scientists are studying how this rare but destructive form of precipitation might be changing in a warming world, drawing on long-term records, new measurements, and computer modeling. One early result: Freezing rain isn’t vanishing—but it is shifting in location and timing. “We want to make an urgent warning that these kinds of winter hazards won’t be less frequent under a warmer climate,” says postdoctoral researcher Chenxi Hu, who works with Yang. Instead, in the ...
