Not entirely the same of course, but most climate-change articles I've read that do mention evolution suggest that climate change is happening too fast for species to adapt in an (for want of a better word) orderly fashion, i.e. without drastic die-backs.

In this connection, fact that acidification is occurring to a measurable extent must at least (imo) be cause for concern.

The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
