Is it more likely that thousands of loosely affiliated climate scientists from 130 countries are involved in one giant scam for no discernable reason or…that multi-billion dollar fossil-fuel interests and other polluting corporations are manufacturing doubt and spreading disinformation because they don’t want to change their ways? I’d wager on the latter — not least of all because it’s happened before: Big Tobacco funded phony research for years in order to claim that “the science wasn’t settled” on the link between tobacco use and cancer. Sound familiar? Not to mention that ExxonMobil has admitted to funding doubt about climate change.

But it’s not just corporations that don’t want to change their ways it’s us too.
