Sea level rose 60 percent faster than UN projections, study finds
By Miguel Llanos, NBC News
Projections for sea level rise in coming decades could be too conservative, experts warned Wednesday, saying they found that the rise over the last two decades is much more than predicted by the U.N. scientific body tracking climate signals.
In a peer-reviewed study, the experts said satellite data show sea levels rose by 3.2 millimeters (0.1 inch) a year from 1993 to 2011 — 60 percent faster than the 2 mm annual rise projected by the U.N.'s Intergovernmental Panel on Climate Change for that period.
"This suggests that IPCC sea-level projections for the future may also be biased low," the team wrote in the journal Environmental Research Letters.
