Global warming is happening, you like it or not, and it’s good to see that the president is concerned deeply about it, in a deep kind of concerned way.
Jokes aside, evidence exists that the White House has sought repeatedly "to mislead the public by injecting doubt into the science of global warming."
Also check out the Breathing Earth, where you can see people being born, and dying, in real time. Hover over each country to see it’s population and how much CO2 it generates nationally.
P.S. - it takes the U.S. only 5.4 seconds to generate 1000 tonnes of CO2.
