Why would water vapor's hold on IR be any different than other GHGs? Seems you have some explaining to do also.
You really don't grasp the science do you? And of course I am perfectly happy to explain it to you if you don't understand. Science isn't exactly sure how the mechanism by which water vapor traps and holds energy, but they are sure that it is associated with the phase changing property that water has. Energy must be stored in order to allow water's phase to change (solid, liquid, gas). While the mechanism isn't precisely understood, the mechanism can be experimentally demonstrated on your stovetop.
Here is the experiment. Do it yourself and watch water absorb and retain heat. A trick that CO2, and all other GHG's simply can not do.
Freeze a thermometer into a block of ice. Use a tupperware container or something like it. See the temperature. 32 Degrees F no matter how cold your freezer is. Put the block of ice in a large pot and put it on an eye of your stove. Turn the heat to whatever setting you choose.
Watch the thermometer in the ice. Clearly, the ice is absorbing heat from the stove but until the ice has phased to its liquid form, its temperature doesn't rise. So long as there is a sliver of ice remaining, even though it is immersed in boiling water, the temperature of the ice will remain at 32 degrees F.
Once the ice has melted, then all of the water in the pot will begin to assume a uniform temperature and it will begin to rise. The water temperature will reach 212 degrees F (boiling) and no matter how hot you turn your stove eye, it will not go above 212 even though it it clearly absorbing heat from the stove eye. The water will remain at 212 until it turns into a gas (steam & water vapor).
If you could contain the steam, you could continue the experiment and see that once all of the water had turned to gas, the temperature would stabalize and from that point you could superheat the water past 212 degrees.
Is there some "new-chemistry" since I've been in school?
Same old chemistry but clearly you didn't learn any of it. Do feel free to describe the mechanism by which you believe CO2 can trap and retain heat.
Funny that you should mention water vapor, the Achilles heel of the skeptics' arguments! If CO2 raised temps even a little, wouldn't that mean more vapor in the atmosphere?
Describe that mechanism.
Would that extra vapor not lead to more warming considering the more potent IR absorption? Co2 may not be the ba-all and end-all of GHGs, but like the amplifier on your stereo, a relatively small adjustment leads to a large change in volume.
Again, describe the mechanism by which you believe this to be true. I am afraid that you won't find a cut and paste because climate guys avoid this topic like the plague. When you get down to the actual science (physics and chemistry) the hypothesis of AGW breaks down.
