|These voluminous "citations" have little to do with the question: Is global warming due to anthropogenic greenhouse gases?|
|Hayduke: Its anthropogenic. You can read about it in the IPCC FAQs. Or you can track down some real papers on the subject.|
To identify what the source of the carbon was, they carbon dated the atmosphere. If old carbon were to be introduced to the atmosphere, the readings would decline. (Because the carbon being put in the atmosphere would have a lower radioactive component. Older Carbon, lower C14.)
Other sources are easier to identify.. deforestation.. etc.
|I agree with the underlying theory here. Atmospheric CO2 is increasing, and CO2 traps heat in the troposphere. The earth is a dynamic system, however. When it comes to energy budget alone, there are dozens of factors to consider. There was only one skeptical argument I've come across that made me stop and think. I can't find the guy right now, but he was a scientist in a semi-relevant field. He basically argued that the net feedback from clouds is complex and not well understood. Clouds supposedly have counteracting feedback mechanisms to solar energy. There is water vapor, which is of course a strong greenhouse gas, but also aerosols in clouds. Aerosols play a duel role of absorb/scattering incoming solar radiation back out to space, and expanding cloud surface area to block some of the incoming radiation (mostly visible light, if not all). There are also a large variety of clouds to make it more complicated. More heat = more clouds. Do these clouds have a net cooling or heating effect? So it was an interesting assertion, sorry I can't remember the details, but that is an example of the skepticism I welcome with open arms. It's quite a complicated topic, which means it's fun haha.|
