(This shows, in effect, that the change in global temperature can
serve as a "medium of exchange" between different feedback effects, even though cloud
formation is not directly a function of temperature.)

does today) and hence may have been relatively dark (as the Malaspino glacier is).

Since the global mean surface temperature of the Earth is
approximately 288 K, the greenhouse strength of the Earth's atmosphere is about 33 K.

processes can be compared in linear fashion, the feedback effects on the global surface discussed explicitly due to lack of
temperature are multiplicative in nature and do not combine linearly.
