Which greenhouse gas would have the greatest effect on the global warming?

Answer 1

Carbon dioxide (CO2) is the greenhouse gas which has the biggest impact on climate change. The CO2 released by human activity is all from the burning of fossil fuels (coal, oil and natural gas). The carbon in fossil fuels has been hidden underground for 300 million years, so releasing it now is too much for the carbon cycle to deal with. So the extra CO2 remains in the atmosphere gathering more heat and causing global warming. Global warming is causing climate change.

Answer 2

Water vapor is far and away the most common green house gas. It makes up 5% of our atmosphere and creates up to 76% of all forcing.

CO2 is second. It makes up 0.03% of our atmosphere and 3 to 26% of the forcing (depending on your source)

The rest of the gases, such as Methane and Ozone make up less then 1% each.

Man produces 0.28% of all green house gases and 6% of all CO2. Much of the CO2 produced by man would be generated naturally if man would not create it.

Nature produces the remaining 99.7%. Much of this from forests. Cutting dead trees and using this wood for homes or other useful purposes prevents them from rotting and giving off CO2. All decaying matter gives off CO2.

Answer 3

Carbon dioxide (CO2) is the most significant greenhouse gas contributing to global warming due to its higher concentration in the atmosphere and its long lifespan. Other greenhouse gases like methane and nitrous oxide also contribute to warming, but CO2 has the largest overall impact.

Answer 4

The gas which we can do most to prevent, and the one that is causing the increase in temperatures, is carbon dioxide, caused by man burning fossil fuels.
