In post 17 I suggested that the fact that volcanic activity does not show strongly in tree rings is due to the fact that volcanic activity mainly reduces temparature in the Summer, whereas trees grow mostly in the Spring. (realclimate.org)
What would therefore have a greater role in affecting temparature increases over this period, water vapor or CO2? (desmogblog.com)
Surely the second step would be to calculate a rate of temparature increase, or to allow the energy retention to operate at the calculated rate for unit time, and calculate the temperature increment at the end of that time, which would have to be short in comparison with the characteristic times of all «feedback» mechanisms?
