6 ways climate science gets infected with politics

Many seem to think that scientists have no reason to have political motivations, and that anyone who suggests that climate science is politicized is a deranged right-wing conspiracy theorist. That’s why it’s important to understand that there are reasons that are in fact well documented if you care to know about them.

Debunking Oreskes Part 4: Disinformation or debate?

← Part 1: A wall of vagueness

← Part 2: The wicked “handful of scientists” 

← Part 3: The “tobacco strategy”

The IPCC and friends have come up with a method of calculating that turns this on its head: the weaker the match between predictions and data, the more certain you become. In this essay, I try to unravel the statistical gymnastics that help make this seem reasonable.
