Polar Temperatures Used to be 3-5 Degrees Warmer

From Discovery:

Sea levels were likely eight meters higher around 125,000 years ago when polar temperatures were 3-5 degrees Celsius (5.4-9 degrees Fahrenheit) warmer, says a new study published Wednesday to show the effects of global warming.

The research by Harvard University and Princeton University was released in the journal Nature as the world's nations met in Denmark to forge a strategy to head off harmful effects of global warming blamed on greenhouse gases.

To understand the potential effects of a rise in temperature, the researchers reexamined data about the last interglacial stage -- a warmer period within an ice age -- which climaxed about 125,000 years ago, they said.

At the time, polar temperatures were 3-5 degrees Celsius (37-41 degrees Fahrenheit)higher than today, providing a comparison for current scenarios of future rises of 1-2 degrees Celsius (1.8-3.6 degrees Fahrenheit), they said.

Really? Do I need to point this out? They did this study to point out the potential effects of global warming. But, in doing so, they gave more evidence to the argument that global warming is natural, it's happened in the past, without mankind interfering, and it will likely happen again. The earth gets cold, then gets warm, then gets hot, then gets cold. Over and over, the record spins.
