[QUOTE="Loudmouth, post: 66579183, member: 11790"] It also captures more of the heat being radiated by the Earth after being heated by shorter wavelength light, such as visible light. CO2 does not absorb these incoming wavelengths. However, it does absorb the outgoing wavelengths. CO2 traps heat. Increasing CO2 traps more heat. Do you think some other factor is going to magically change to compensate for the additional CO2? Just by luck? Let's look at some of those other factors. We could start with natural stores of CO2. Two such stores are the ocean and permafrost. When we add CO2 it warms the oceans. When the oceans warm it causes CO2 dissolved in the ocean to come out of solution and into the air. That adds even more warming. As we add CO2 and cause warming, more permafrost melts and all of that carbon is digested by microbes that release methane. Methane is an even more potent greenhouse gas than CO2, but luckily it doesn't last as long in the atmosphere as CO2. Methane is oxidized in a few years by free oxygen, and it is oxidized to . . . you guessed it, CO2. [/QUOTE]
