“A majority of that increase took place since 1970, the report states. And the most recent decade was the nation’s hottest on record, with 2012 being the hottest year on record in the U.S. “

Isn't around 1970 when we started implementing emissions controls?

So using techniques from the AGW "correlation = causation" school of science, I'd have to include that the warming is caused by pollution controls. We'd better close the EPA if the planet is to have any chance of surviving.

I’m blaming the banning of leaded fuel then.
