Some people wonder – how can anyone deny climate change? It is so obvious that the weather is getting warmer. Don’t the deniers ever go outside?

Here’s a map that might explain it, at least in the United States. It shows the deviation from the temperatures of 20-40 years ago. Red means that temperatures are hotter now than they were and blue means cooler (ignore the big circle on California).

People living in the middle of the country – the bluish ‘flyover states’ – aren’t really feeling the heat.

Now look at this map of the 2016 US presidential election results. Red states in the middle of the country went for Donald Trump.

The second map is a pretty close inverse of the first one. So when people say they don’t believe it is getting warmer, if they live in the middle of the country they are right. They aren’t getting warmer. And by the time they do get warmer, it will be too late to do anything about climate change.
