“”There are apparently lots of people who really do think that global warming is an evil socialist plot,”
This is the standard approach of AGW advocates. The issue isn’t whether the world has warmed relative to the past: it is whether and how much of it can be attributed to human activity in general (anthropogenic global warming), and CO2 emissions in particular. If the answer is little or none, then it is bone-headed to squander trillions of dollars in global output in a futile effort to reduce CO2.
AGW may well be an evil socialist plot: certainly these emails give some credence to that claim.
What you said.
It's also worth pointing out that any data supporting the claim of AGW, if it exists, these "scientists" will refuse to produce to the public.
