The New York Times has an interesting interactive web site which shows you how many days per year your hometown is above 90 F now and how that is likely to change over time. It also compared your hometown to other parts of the world, many of which will feel a lot more heat than we do in the Southeast. You can try it out at https://www.nytimes.com/interactive/2018/08/30/climate/how-much-hotter-is-your-hometown.html.
