I haven’t drank the anthropogenic global warming koolaid, but playing the devils advocate on the sentiment of this article leads one to see that total emissions in the USA is 25% higher than all of Europe. Put another way- the 300plus million people in the USA are producing 25% more emissions than the 700plus million living in all of Europe.
If liberals really cared about our CO2 emissions, they'd be in favor of booting 11 million illegal aliens.
They emit much more CO2 here than they would back in their home countries.
