2012 was the hottest year since 1895. That’s 117 years by my count. Of course just being the hottest year ever recorded does not mean everywhere was warmer than usual. Some places were cooler. And the New York Times looked at the US pattern of warmer and cooler than average temperatures. Below the map are small multiples of charts recording the number of days above or below the normal for that day.
And for anecdotal evidence, I will say that this past summer was godawfully hot in Chicago.
