Which greenhouse gas contributes least in global warming?

1 However, a number of analyses suggest that the non-CO 2 greenhouse gases included in the Kyoto Protocol—methane, nitrous oxide, and the high-GWP (global warming potential) gases (HFCs, PFCs, and SF 6 )—can make a significant contribution to cost-effective emission reductions for the US and other countries.

Here, we present a new estimate of national contributions to observed climate warming, including CO2 emissions from fossil fuels and land-use change, as well as methane, nitrous oxide and sulfate aerosol emissions While some countries’ warming contributions are reasonably well defined by fossil fuel CO2 emissions, many countries have dominant contributions from land-use CO2 and non-CO2 greenhouse gas emissions, emphasizing the importance of both deforestation and agriculture as components of a country’s contribution to climate warming.
Greenhouse warming by gaseous CO2 and H2O by itself is in conflict with constraints on atmospheric CO2 levels derived from paleosols for early Earth.
