"Global Warming" is not my area of expertise, but the dramatic cycles into and out of ice ages over the past half-million years or so have, based on ice core measurements as a proxy for temperature, caused the global average temperature to fluctuate by as much 12oC over this period. These fluctuations dwarf the changes observed from "global warming" thus far [whether that remains the case in the decades/centuries to come is another matter].
