“Consensus” is a word you hear a lot these days. And when you hear it, there’s a good chance you’re being told to keep quiet about something. For example, you might notice that celebrities are flying an awful lot for people who claim to be concerned about climate change. And you might find it odd that politicians like Barack Obama are buying up giant seaside properties if they think the oceans are about to rise and wipe entire continents off the face of the Earth. And then you might notice that average temperatures in your area haven’t changed much in the past century.
These kinds of observations might lead you to question whether man-made climate change is really a big deal, or even if it’s happening at all. And in response, you’ll be told that your questions are irrelevant. They’re an affront to science, in fact, because a consensus has already been reached among experts.
