Climate change deniers are wrong when they claim that the predictions made by climate models are unreliable. As I show here, most of them are very accurate—and where they get it wrong, they're more likely to *underestimate* the warming (or associated consequences) than overestimate it. The most inaccurate predictions are actually those made by climate change "skeptics."

I also show some of the problems in the data and graphs used to support this viewpoint, and I debunk a variety of related arguments, including one made by Jordan Peterson about whether can measure the impact of our climate-related actions.
