| Linkzmax said: I wasn't only speaking about CO2, but while it is higher than ever before that doesn't prove that the majority of the contributions areman-made. http://mysite.verizon.net/mhieb/WVFossils/greenhouse_data.html seems a bit outdated, as some of its sources have been updated, but it points to ~5% of greenhouse gases being man-made, and only ~.3% once you include water vapor which is by FAR the biggest greenhouse gas. |
Water Vapor is a funny thing. It is true that it retains more het than CO2 or Methane however it doesn't reach a critical level until the temperture has increased enough to allow the air to carry it. The other funny thing about Water Vapor is that when it reaches a certain amount it condenses and forms clouds these clouds have a cooling effect where as CO2 and Methane do not reach such a level and will always react with Infrared light realesing it as heat. Methane is a far worse Greenhouse gas than CO2 by the way. Water Vapor tends to eb more self regulating than the others which makes it the least serious of the atmospheric offenders over the long term.
