Evolution doesn't drive climate change.
What makes you think that's where I was going?
Indirectly it does. Much (if not most) of the greenhouse gasses are produced by rotting trees (rotting due to bacteria) that were flooded by dams created by beavers.
well, it could, and seems to have done so dramatically in the distant past - the rise of photosynthetic organisms appears to have radically altered the atmosphere's chemical composition by liberating molecular oxygen and binding carbon into biomass. These alterations certainly could (and apparently did) contribute to massive climate shifting.
Additionally, forests are rain-engines. No forests, no land-based rain-engines. When trees came to be and formed forests *poof!* we had land-based rain-engines. Does this not qualify as climate change driven by evolution?
