Someone cast Wolven Winter on New Orleans!

Thank you for your reply edi, unfortunately I don't have time to discuss or clarify some of your misconceptions about the work (leaving for France in 4 hours...) but I will question one thing:

If the difference is similar, even modest CO2 increases would show increased temperatures.

Clearly though, this is not the case, historically or currently.

Further you need to source your claim about CO2 having a greater greenhouse effect than water (unless this isn't your claim). It is generally accepted that water vapor has a greenhouse effect of 2-5x that of CO2. I'm talking about the entire picture, which takes into account both efficiency and total concentration.

So yes, CO2 for its concentration has a large effect, but its concentration is tiny compared to water, though likely more volatile, however, still not at anything near historic levels.
