Rapid Sea Level Rise? To the Contrary, Nature Says
“The short-term rate of global sea level rise has decreased by about 25% since the release of the AR4—and a new paper shows that some 15% of the observed rise comes not from global warming, but instead from global dewatering…. [R]ather than raising its projections of sea level rise, perhaps the IPCC ought to consider lowering them once again.”
The Intergovernmental Panel on Climate Change (IPCC) is under pressure to revisit its projections of the expected amount of sea level rise by the year 2100. Many rather influential types are pushing for the IPCC to dramatically increase its central estimate by some 2-3 times above the value given in the IPCC’s Fourth Assessment Report (AR4).
Not so fast!
Nature speaks with a contrary voice, political agendas aside. The short-term rate of global sea level rise has decreased by about 25% since the release of the AR4—and a new paper shows that some 15% of the observed rise comes not from global warming, but instead from global dewatering.
In light of all this, rather than raising its projections of sea level rise, perhaps the IPCC ought to consider lowering them once again (as it did from its from its First Assessment Report to its Second, and from its Second to its Third). [Read more →]
