As the world continues to warm from the increase of greenhouse gases, the amount of extreme cold during winter will start to decrease. According to a 2013 report by Climate Central, nationwide nighttime winter temperatures since 1970 have risen about 30 percent faster than nighttime temperatures over the entire year. Every NOAA climate division has shown warming, with the Upper Midwest, Great Lakes, and New England warming the most over the past 45 years.
