Green House Gases Other than CO2


Carbon dioxide remains the largest by mass of potential green house gases affecting 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. Discussions with colleagues around the time of the 2009 United Nations’ climate conference in Copenhagen inspired three NOAA scientists – Stephen Montzka, Ed Dlugokencky and James Butler of NOAA’s Earth System Research Laboratory in Boulder, Colo. – to review the sources of non-carbon dioxide (CO2) greenhouse gases and explore the potential climate benefits of cutting their emissions.
