The blog shows how one can cleverly display data to reinforce a prior belief. In this case the prior belief is that temperature is not rising. Recently I’ve encountered a number of people making the claim that temps have been declining. I’ve wondered why this claim is being made and now I know the source. As shown in the blog post the source is a purposefully misleading graph. As stated by the author this misleading graph has recently been making the rounds on the internet.

“Recently, several times I’ve run into people tell me that temps in the U.S. are rising and I’ve wondered why they make such a claim.”

As written, your comment sounds like you don’t understand why someone would say temperatures are rising, and ascribe it to confirmation bias rather than climate change.
