The direct warming influence of all long-lived greenhouse gases in the atmosphere today attributable to human activities. CO2’s warming influence of 1.7 watts/m2 is equivalent to the heat from nearly 9 trillion 100-watt incandescent light bulbs placed across Earth’s surface. The combined influence of the non-CO2 greenhouse gases is equivalent to the heat from about 5 trillion bulbs. The category “other”includes a few very long-lived chemicals that can exert a climate influence for millennia.

Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions of those other gases could slow changes in climate that are expected in the future
