How to Tell If Someone Is an Idiot

The U.N.'s World Meteorological Organization announced last week that the rise in greenhouse gases in the atmosphere accelerated to a record high in 2012. Carbon dioxide, the main heat-trapping gas, was responsible for 80% of the jump, pushing concentrations to levels not seen in at least 800,000 years.

So... 800,000 years ago, the atmosphere had exactly as much CO2 as it does now.

And it's all the fault of human industrial activity.

You know... like the human industrial activity we had 800,000 years ago.

Idiots.
