The planet may be warming, and humanity has definitely caused environmental degredation in the industrial age. Regardless, I believe the story of global warming that we are being sold is the next Big Lie and yet another iteration of Oz-like wizardy and coerced sacrifice to appease the Sun God. More bluntly, it creates a new tax structure to ensure the status quo before long suppressed energy technologies threaten to give us too much freedom from energy companies.
Yes, we are all environmental sinners, who must each offer sacrifice and consternation at this problem that we all created, nevermind that auto companies and oil companies haven’t figured out how to increase fuel efficiency or replace the combustion engine (despite the fact that cars have run on water). Nevermind chemtrails and the military’s likely success in weaponizing the weather (see Kucinich’s space bill). Nevermind that the US military is the single largest consumer of fossil fuels. Do as your church tells you, sinner, but nevermind that your priest is a pedophile.
So, here’s an article that isn’t the best refutation I’ve read, but that does poke holes in the IPCC report cited by @Marina. It also does something interesting, which is to liken GW/GCC believers to conspiracy theorists in their “need” for a grand evil that threatens to doom the planet and the propensity to see false positives.
