What they are referring to is a paper by Mojib Latif in which he notes that the media often misrepresent global warming as a continuous, year by year increase in temperature. The truth, of course, is that annual temperature varies up and down but the baseline for this variation has been going continuously up.
Like a road going up a mountain. Often the road goes up and down and up and down cross the complex terrain of the mountain side. If, while driving up this hypothetical mountain, the road dips down for a moment, one does not say “Oh, we’re going home now. This whole driving up the mountain thing is over. We just dipped down. No more up. That’s the end of it.” and then turn around and drive home.
I mean, really, this is pretty freakin’ simple.
