Why Seas Are Rising Ahead of Predictions: Estimates of Rate of Future Sea-Level Rise May Be Too Low


ScienceDaily (Nov. 1, 2012) — Sea levels are rising faster than expected from global warming, and University of Colorado geologist Bill Hay has a good idea why. The last official IPCC report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100. But current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century.

U.S. Department of Agriculture designated all 83 counties in Michigan as primary natural disaster areas after a premature spring followed by a seasonal but killing frost, summer drought and excessive heat conditions.

It would be funny if dults like these didn't dominate the legislative branch in this country. But at least they didn't legislate that sea level isn't rising - so I guess that passes for progress these days.

Currently at Extremes:

According to satellite data, we are at record high global average temperatures (2010) and record low Arctic ice extent for this time of year. And ice extent now is way below the 2007 level, the year that set the record for the September/annual minimum ice extent.
