Thanks to those wonderful 'greenhouse' gases: without them, the world would be a frozen, lifeless wasteland!! The common greenhouse gases, including water vapor, (the most plentiful of the greenhouse gases), are:

Water vapor 0.40% of the total atmosphere

Carbon dioxide, without which most plants would die 0.04% of the total atmosphere.

Methane close to 0%

Ammonium close to 0%

All of these together make up less than 1/2% of the world's atmosphere, but are 100% responsible for keeping us alive. Are we really sure we want to mess with these numbers? If we do, we could tip the scales toward an unstoppable worldwide ice age.
