Debate:Is global warming evident, and if so, is this the fault of man, and how must man stop it? (view source)

I personally am very skeptical of the current "global warming" frenzy. It just doesn't appear to have much solidity to it, and even if the earth is warming, the environment is highly self-regulatory. Warmer temperatures mean increased evaporation. Now it is true that water vapor is a greenhouse gas, but as it condense in the atmosphere, it forms clouds, which block the suns rays, dim the surface, and effectively lower temperatures. I personally believe that the earth might warm, but only to a certain point, at which natural systems would work to cool it again. --[[User:Blu Aardvark|Blu Aardvark]] 09:33, 26 March 2007 (EDT)

:I would certainly agree with the above. Add to it that if carbon dioxide increases in the atmosphere, then vegetation will take it up--along with the increased rains.--[[User:TerryH|TerryH]]<sup>[[User talk:TerryH|Talk]]</sup> 09:41, 26 March 2007 (EDT)

::I guess Terry and Aardvark that you both do not understand chemistry and radiation. Yes more water vapor means more clouds, however clouds do not block the right wavelength of light. You can receive sunburn on a cloudy day, UV penetrates many cloud masses and reaches the earth. When the light is reflected back to space however its energy is reduced and is stopped from escaping the atmosphere by the clouds thus causing convection in the atmosphere. If you do not believe what I just stated then think about Venus, the atmosphere is cloud covered all of the time.--[[User:Tims|TimS]] 10:24, 26 March 2007 (EDT)
::On to water vapor. Water vapor has high heat absorption and is very effective at retaining heat. So the more water vapor there is in the atmosphere the higher the temp. Since the higher the temp the atmosphere has a greater ability to gain more water vapor. This cycle continues till equilibrium is established however by our adding of other green house gasses this equilibrium is continually offset.
Aardvark, lets put this in perspective about the natural systems cooling the earth again. Paper trash breaks down over time in dirt and weather. But the more paper trash we add to the system the longer it takes to break down. If we continue to add over what the system can break down normally we end up with a build up. Same thing with the Green house gasses. The Atmosphere can breakdown certain gasses however with the continual addition of gasses we end up overwhelming the reactions that break the gasses up. If you exceed the limits of the natural system it will not work.
TerryH, additional CO2 and deforestation renders your statement moot. We have been exceeding what vegetation can keep up with for years, if not then the hole in the Ozone would have closed or remained unchanged. We are not seeding new rainforests at the rate we are cutting them down, nor are we replacing the vegetation that we remove when expanding our living areas. Come now think about what you just said.--[[User:Tims|TimS]] 10:24, 26 March 2007 (EDT)
