terrestrial plant
life, too):
While the conditions in the geological past are useful indicators in suggesting climate and atmospheric conditions only vary within a a certain range (
for example, that
life has existed
for over 3 billion years indicates that the oxygen level of the atmosphere has stayed between about 20 and 25 % throughout that time), I also think some skeptics are too quick to suggest the lack of correlation between temperature and CO2 during the last 550 million years falsifies the link between CO2 and warming (too many differences in conditions to allow any such a conclusion to be drawn —
for example the Ordovician with high CO2 and an ice age didn't have any
terrestrial life).
