You just made the case for the skeptics! Thank you! That's EXACTLY what we've been saying!
If there are "lots of other factors too" (variations in Earth's magnetic field, albedo effect, urban heat island measurements) how much is attributable to the de minimis increase in CO2? .002F?
The AGWCult is just pulling numbers out of the air because they know how unkind any laboratory experiment is to their USA killing "theory". Very likely there is virtually no warming from the increase in CO2, it's a small fraction of a degree, far less than even a tenth of a degree
