The differences between Current warming and PETM warming.
The SciAm article is good and I urge those interested to read it in its entirety at http://physics.ucf.edu/~britt/Climate/Reading1-Last%20great%20warming.pdf
Back then, around 56 million years ago, I would have been drenched with sweat rather than fighting off a chill. Research had indicated that in the course of a few thousand yearsa mere instant in geologic timeglobal temperatures rose five degrees Celsius, marking a planetary fever known to scientists as the Paleocene-Eocene Thermal Maximum, or PETM. Climate zones shifted toward the poles, on land and at sea, forcing plants and animals to migrate, adapt or die. Some of the deepest realms of the ocean became acidified and oxygen-starved, killing off many of the organisms living there. It took nearly 200,000 years for the earths natural buffers to bring the fever down
But the most jarring aspect is contained in this one graph:
