Not exact matches

Fresh headlines followed publication of «Ebullition and storm - induced methane release from the East Siberian Arctic Shelf,» a new Nature Geoscience paper from Natalia Shakhova, Igor Semiletov and the rest of a team tracking emissions of this important greenhouse gas from the seabed and shallow waters off Siberia.

Also note that human induced warming probably will trigger natural C02 / methane emissions leading to further warming so anthropogenic source will probably play a decreasing role in the amount of C02 in the atmosphere as the planet moves to a new equilibrium point.

Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.

Countries included in Annex B of the Protocol (most Organization for Economic Cooperation and Development countries and countries with economies in transition) agreed to reduce their human - induced heat - trapping gas (greenhouse gas) emissions (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) by at least 5 % below 1990 levels in the commitment period 2008 to 2012.
