I think the actual figure is that methane is ~24 times more effective as a greenhouse gas than CO2. For real information on global warming and climate change, move on over to http://www.realclimate.org. That's a site run by actual climate scientists, and there is no doubt in their minds about mankinds changes to the environment. As for termites, you can color me skeptical. http://www.epa.gov/methane/sources.html lists methane from livestock (see enteric fermentation) as about 20% of US methane emissions from human related sources, following landfills and natural gas systems. http://www.brightsurf.com/news/oct_02/AGU_news_100902.html certainly makes it sound like the majority of methane released (60%) to the atmosphere is related to human activity. Google doesn't seem to have much on termites, methane, and global warming in the first few pages of results, that would indicate termites are a significant source. --- David _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
