SUMMARY: The European Space Agency's Envisat has completed a map of global methane emissions, and not surprisingly, areas of dense population show the highest levels of this greenhouse gas. What is a surprise, however, is that there are higher emissions than anticipated over tropical areas of the planet. This could be because of burning, termites, animals, or just increased decomposition of plants. Methane gas traps 21 times more heat per molecule than carbon dioxide, so it's important to locate these sources and limit them.

The first line of the posting summary (below) reworded the original ESA material in a way that is incorrect. The image is NOT a map of global methane EMISSIONS; it is a map of methane CONCENTRATIONS in the atmosphere, particularly the troposphere. It is similar in some respects to the pattern of emissions, but in addition to emissions, atmospheric concentrations are affected by transport, chemical destruction of methane in the atmosphere. season etc.

"Summary - (Mar 18, 2005) The European Space Agency's Envisat has completed a map of global methane emissions, and not surprisingly, areas of dense population show the highest levels of this greenhouse gas. "

i agree with ematthews it seems a lot more reasonable then at first and in order to get a map of methane emissions of earth it would have to be done by plane. <_< :rolleyes:

There was some prior discussion of many of the points of this article in the forum
