But don't worry -- U.S. carbon dioxide emissions are now back to where they were in 1990, mainly because the economy is back to where it was in the Stone Age.
From the article: “Minimal petrol taxation and lack of climate policy contribute to American greenhouse gas emissions and energy use per person being among the world’s highest.”
That’s a sign of wealth and liberty. All the Americans who think otherwise please emigrate to the country of your choice.
