This was the first story in an excellent recent series by The Washington Post, examining locations around the world where local temperatures have already risen more than 2 degrees Celsius since the preindustrial era. (According to the terms of the Paris climate agreement, world nations are working to keep global temperatures from rising more than 2C.)
For this story, the reporters analyzed NOAA data at the state and county level from the years 1895 to 2018, calculating annual mean temperature trends. In this way, they determined which counties across the country have already warmed by at least 2C. The story includes a national map, and an interactive component that allows readers to search the list of counties and see how much each has warmed.
The story goes on to look at specific climate impacts in some of the fastest-warming states in the nation, identified by the data. It includes not only interviews with climate scientists, but characters from each location the reporters visited -- real people affected by the consequences of the ongoing warming.
