US Winters Warming Faster – Report

While the US as a whole has seen a warming trend that has raised annual average temperatures by 1.3°F over the past century, warming varies seasonally, and it’s winter that has seen the fastest warming, says a new report by Climate Central that analyzes data from the U.S. Historical Climatology Network of weather stations. It shows that the coldest states are warming the fastest, and across the country winter warming since 1970 has been more than four-and-a-half times faster per decade than over the past century. The winters of the five fastest states have warmed at least 4 degrees Fahrenheit in the past 4 decades.  Winter nights have warmed about 30 percent faster than nights over the whole year. Winters in 13 states, 10 of which are in the South, cooled or failed to join the warming trend over the past century, but since 1970, every state has shown winter-warming.  The pattern of winter warming differs from yearly warming. Some of the fastest-warming states overall, such as Arizona, New Mexico and Colorado, have had some of the slowest-warming winters, both since 1970 and over the past century.

 WINTERS WARMING FASTEST IN COLDEST STATES A dramatic winter warming trend has developed since 1970, with the coldest states warming the fastest, according to an analysis of 101 years of temperature records. The data, collected from thousands of government weather stations, is analyzed in our latest report Warming Winters. The report includes a state-by-state interactive illustrating how winter temperatures have warmed since both 1970 and 1912.
