Ancient Global Warming Discovered

From via The Drudge Report:
An extraordinary burst of global warming that occurred around 55 million years ago dramatically reversed Earth's pattern of ocean currents, a finding that strengthens modern-day concern about climate change, a study says.

The big event, the Palaeocene/Eocene Thermal Maximum (PETM), saw the planet's surface temperature rise by between five and eight degrees C (nine and 16.2 F) in a very short time, unleashing climate shifts that endured tens of thousands of years.
But wait. Mankind was certainly not around 55 million years ago, and as we know from environmental activists, only evil, greedy capitalists cause global warming.
What unleashed the PETM is unclear. Most fingers of blame point to volcanic eruptions that disgorged gigatonnes of carbon dioxide, or coastal reservoirs of methane gas, sealed by icy soil, that were breached by warmer temperatures or receding seas.
You know, I could have sworn that Rush Limbaugh was excoriated as a Neanderthal for suggesting that volcanoes could cause global warming.
