Only if one excludes water vapor.
Really?
I didn’t realize that. Thank-you.
I recently also read that CO2 only absorbs select frequencies of infrared radation. As you increase atmospheric concentrations of CO2, each increment traps less and less heat until it levels off logarithmically.
Another thing that the GW people are not answering (that I can find anywhere) is why temperatures have dropped since 1998 even as CO2 production has continued to increase. There are so many holes in their theory that their credibility drops by the day and yet politicians are setting policies that require all of us to reduce our quality of life based on this junk science.
