Its not slower AFAIK. The term is "glacial", the opposite of "interglacial". A glacial consists of "stades" and "interstades". Typically there are 3 stades and 2 interstades per glacial, but sometimes only 2 stades and 1 interstade. A graphic: http://en.wikipedia.org/wiki/File:Carbon-dioxide-temperature-plot.svg
The long, slow is the gradual decline in temperature due to the gradual converstion of CO2 into carbonates. Here we see the decline over the past 5 million years: http://www.globalwarmingart.com/wiki/File:Five_Myr_Climate_Change_Rev_png As for your orginal question, my amateur understanding is that it is still called equilibrium climate sensitivity. -- You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
