LAST WARMING PERIOD RAISED SEA LEVELS 26 FEET
AFP - Sea levels were likely eight meterS [26 feet] higher around 125,000 years ago when polar temperatures were 3-5 degrees C [5-9F] warmer, says a new study published to show the effects of global warming.
The research by the US universities of Harvard and Princeton 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 C higher than today, providing a comparison for current scenarios of future rises of 1-2 degrees C, they said.
"We find a 95 percent probability that global sea level peaked at least 6.6 metres (nearly 22 feet) higher than today during the last interglacial," the study said.

I wish someone would explain how the levels were brought down to current levels. Was it curly lightbulbs, carbon trading, mileage standards or what?
