MIT researchers developed a new tool to model the number of “outdoor days” - with comfortable temperatures for outdoor activities – and found that Southern states in the U.S. will lose a significant number of outdoor days, reports Kristin Toussaint for Fast Company. Prof. Elfatih Eltahir explains that the concept of outdoor days is, “an attempt for me to bring the issue of climate change home. When someone tells you global temperatures are going to increase by 3 degrees, that’s one thing. If someone tells you that your outdoor days will be dropping by 20% or 30%, that’s another thing.”
