Winters are warming faster than summers in North America, impacting everything from ecosystems to the economy. Global climate models indicate that this trend will continue in future winters but there is a level of uncertainty around the magnitude of warming. Researchers focused on the role of carbon dioxide emissions in this equation — looking at the effects of both high and low levels of carbon dioxide emissions on future climate warming scenarios — and found that a reduction in emissions could preserve almost three weeks of snow cover and below freezing temperatures.
