If you've been worrying that recent storms are linked to climate change, you're right on the mark, according to climate experts such as Michael Mann.
Mann explains that we're seeing bigger storms with more snow because of global warming, and compared Nemo and Superstorm Sandy "to a basketball slam-dunk with a lower net." "If you take the basketball court and raise it a foot, you're going to see more slam-dunks," said Mann to HuffPo's Lynne Peeple's.Michael Oppenheimer, a climate expert at Princeton, agrees. "Storms like this tend to be heavier than they used to be," he told HuffPo. "That's a fact."
In weather terms, that's because warmer temperatures and a moister atmosphere make snowstorms heavier. What we've seen recently is a trend for storms that occur at just-below-freezing temperatures, which means bigger snowfall. "In the past, temperatures at this time of year would have been a lot below freezing," making it too cold for heavy snowfall, said Kevin Trenberth of the National Center for Atmospheric Research in Colorado. "Sea surface temperatures are about two degrees Fahrenheit warmer than they were before 1980, raising the potential for a big snow by about 10 percent," according to HuffPo.
