Well said! My view evolved when I compared apples to apples, which was just converting water vapor to parts per million. H2O and CO2 both have 3 molecules, and H2O is bent, so it has even more degrees of freedom when absorbing IR energy. In Florida on a typical summer day, mornings start out at about 25,000 ppm of H2O and spikes to 35,000-40,000 ppm in the afternoon. Phew. 100-200 ppm is absorbed into rounding error. I'm off by 1000-5000 ppm. Furthermore at ~STP, a dew point of -27F gives you 200 ppm of H2O, and a dew point of -20F gives you 400 ppm of H2O. Again, lots of rounding error, but I think the point is made. I don't know what substantial radiative differences occur between those 2 dew points. Somehow that is enough to lead to enhanced baroclinic energy conversions causing severe weather outbreaks in November? I don't think so. Of course, respect Mother Earth. She will kill us all :)

Glaciers recede and advance for a variety of reasons. Temperature is one factor, precipitation is another and ablation is yet another. So true. There is a glacier in NW Canada that recently has receded and revealed a 7,000 year old field of perfectly preserved tree stumps.. Why is this relevant? Because it means that before that glacier advanced and ripped that forest apart, very healthy trees were growing there.. Which means that global temperatures had to be warm enough for those trees to grow for years.. livescience.com And another such story.. which supports the view of a Medieval Warming period that was hotter than present day. iceagenow.info When those trees start growing into a forest again, then we might say that we've equaled previous periods of global warming..
