Hi All There is a useful NOAA release at
http://www.noaanews.noaa.gov/stories2009/20090421_carbon.html They give the Mauna Loa graph extended by ices cores and plotted together with fuel burn, GDP (now $60 trillion) and population. It was sensible of them to use a log scale. Methane is up over the last two years after a 10 year lull but they repeat the times 25 factor mistake. Even so they say now that the methane contribution is now nearly half that of CO2. The 1929 depression shows up in the ices core CO2 so let's all be grateful for the 2009 one and the far-sighted wisdom of our wonderful bankers. There was also a reduction for WWII but this is maybe not the most cost effective method.
