"Sea Level Rise Accelerating Faster than Initial Projections"

"Sea level is rising as the planet warms up, but how much it will rise, and how fast is still something climate scientists are working out. And according to study released late Tuesday in Environmental Research Letters the ocean is already rising faster than the most recent authoritative report from the U.N. Intergovernmental Panel on Climate Change (IPCC) was projecting as recently as 2007."

"'Results show that global temperature continues to increase in very good agreement with the best estimates of the IPCC," the authors of the new study write. "The rate of sea level rise of the past decades, on the other hand, is greater than projected by the IPCC models. This suggests that IPCC sea level projections for the future may also be biased low.'

The IPCC issues comprehensive reports every five to seven years, with the next one due out in 2013-2014. The reports summarize the state of scientific knowledge on climate change, and are used as the underpinning of interational climate talks aimed at reducing greenhouse gas emissions. The latest round of these negotiations is currently underway in Doha, Qatar."
