From :Have Changes In Ocean Heat Falsified The Global Warming Hypothesis? - A Guest Weblog by William DiPuccio
"IR radiation that is absorbed and re-emitted by these gases, particularly CO2, is said to be amplified by positive feedback from clouds and water vapor".
I am still working through this "paper". A question arises whenever I read the above statement about amplification, how in nature do you get something for nothing? Is it just a poor use of words?
Thanks
