From several sources it was calculated that the world annual emissions of the big 4 GHGs were as follows. The data does not account for water vapour or natural emissions.
* CO2 30 billion tons * CH4 7 billion tons * Nitrous Oxide 3 billion * Fluorocarbons 3 billion
No.
They make everything hotter
China
The production of greenhouse gasses is harmful to the environment, causing an enhanced (or accelerated) greenhouse effect which is causing global warming. The gases emitted include methane and carbon dioxide.
China produces significantly more greenhouse gasses than the U.S. But, the U.S. is second.

No, the greenhouse effect is the effect of certain gasses such as carbon dioxide and methane (called greenhouse gasses) trapping heat near earth's surface. There is a natural greenhouse effect that keeps earth from becoming too cold, but there is some concern that human actions may be putting extra greenhouse gasses into the air and causing average temperatures to rise.

Humorous answer: greenhouse gasses Correct Answer: Carbon dioxide, just like when outside and not in a greenhouse.
Nature creates greenhouse gasses by having cows fart.
The production process calls for many substances that release greenhouse gasses when used. It's said that producing half a pound of hamburger releases as much greenhouse gas as driving a car 10 miles.
