So
why was the sea level rise accelerating so much from 1940 to 1970 when global temperatures were going down?
The main
causes are sea level rise, coastal development, human activity and oil spills, the report said.
Currently about 90 percent is taking place in the oceans where the primary
consequence is sea level rise due to thermal expansion and potentially more powerful and frequent tropical storms.
The question I hope the appropriate scientific community is addressing is
why is sea level rising 50 % faster than the modeling projected?
The highest elevation is Hunter Mountain, at approximately 4,040 feet (1,232 m) above sea level; the lowest
is sea level along the Hudson.
In addition, there
is a sea level pressure (SLP) ridge over Greenland that drives strong northerly winds through the Fram Strait, facilitating ice export.
Impacts of special
interest are sea level rise and species extermination, because they are practically irreversible, and others important to humankind.
So, not
only are sea levels changing at a rapid clip, but we have also built a tremendous amount of infrastructure (such as houses, highways, utilities and nuclear power plants) right on yesterday's coastline.
Ocean heat content increase as I said in ARGO was fairly modest
as was sea level rise.
Also not factored in to the results of this
study is sea level rise, which is considered the surest influence of warming on future hurricane impacts.
The more important point is that the one known
unknown is sea level rise: all the other IPCC stuff is OK by me apart from being at least a few years out of date.
The only thing that prevents me from thinking that it is
all is sea level as measured by tide gauges, but recent evidence that a significant fraction of SLR may be caused by subsidence that we are only just barely beginning to measure with universal GPS access is making me wonder even about that.
To take the IPCC's average sea level rise of 38.5 cm (which, six years ago, it tipped at 48.5 cm) as a starting point, this would mean, according to some of the world's leading scientists, that Al Gore, who in his movie An Inconvenient Truth dramatically shows what the worlds coastlines would look
like were sea levels to rise by 6.1 m, is off by more than a factor of 15 times.
Given that a climate sensitivity to CO2 doubling in the region of 2.5 - 3K is not seriously disputed and that we are rushing headlong to achieve this within 50 years, the only questions are where between 6 and 27m higher
is sea level going to end up and how long it will take.
Figure 1 (below)
is the sea level pressure field for June and July 2009, showing the Dipole / negative Arctic Oscillation pattern with high pressure on the North American side of the Arctic.
