I figured that the rest of you stuck inside during your summer vacations like me, and for me this is my last summer, would appreciate this blog post by Time's science writer. Essentially his point is, there is no way to tell for sure how Global Warming affects individual heat waves but be ready for more frequent and hotter waves than would otherwise occur:
Next summer may not be especially hot--but over the next several decades, expect more and more heat waves like this one--and a few that are even worse. Expect them to show up more often, last longer and affect larger areas. And expect those other signs of warming--the storms, the droughts, and even such counter-intuitive events as the unusually harsh, snowy winter now going on in South Africa--to come along more often and be more severe as well.
