In 2006, Man's Greenhouse Gases Added 340 Megatons a Day The US NOAA just published the Annual Greenhouse Gas Index, or AGGI, for 2006. (It's about time! 2007 is half over.) These figures track 5 major and 10 minor anthropogenic greenhouse gases. During 2006, and increase of 0.032 Watts of energy were not radiated to space for every square meter of the Earth's surface. This increase, primarily due to the additions of the gases CO2 and N2O into our planet's atmosphere, is the energy equivalent of 340 million tons of TNT every day. (The calculation is below.)
The NOAA AGGI page is here: http://www.esrl.noaa.gov/gmd/aggi/ For a graph of the yearly concentrations of the 5 major anthropogenic greenhouse gases since 1979, please see: http://www.esrl.noaa.gov/gmd/aggi/aggi_fig2.png =-=-=-=-=-= -- Please see table 2 at: http://www.esrl.noaa.gov/gmd/aggi/ -- The added forcing is the 2006 total forcing minus the 2005 forcing. TotalForcing = 2.665 - 2.633 TotalForcing:0.032 ---- Radiative Forcings in Megatons TNT -- The diameter of the Earth is ~12756000 M. -- Please see: http://pds.jpl.nasa.gov/planets/special/earth.htm ERadius = 12756000/2 ERadius:6.38e+06 -- The surface area of the Earth is EArea = 4*π*ERadius^2 EArea:5.11e+14 -- The energy of 1 Megaton of TNT = 1.16111E12 Watt Hours.
