You are correct that periods of climate change including global warming and cooling, as well as species extinctions as well as those of higher taxonomic groups, is natural.

What does NOT appear to be "natural" with respect to this period of global warming and the current extinction episode is the RATE at which these changes are occuring. It is this RATE of change that is of greatest concern to most informed biologists, climatologists and others.
