Greater Acceleration of Global Sea-Level Rise than Previous Estimates
New research out of Harvard University shows that previous estimates of global sea-level rise from 1900-1990 were overestimated by up to 30 percent.
However, since 1990 sea-level rise estimates have been confirmed by this new research which means that the rate of sea-level change was actually increasing more quickly over the past century than what was estimated by other experts.
Interesting. Does this seem similar to the typical Warmist pattern of cooling the past and warming the present? Anyhow, how bad is it? The graph at the link states 3.2 +/- 0.4mm year from 1993 forward, which, interestingly, shows no acceleration during that time period. But, of course
Earlier estimates showed a sea-level rise ranging from 1.5-1.8 mm/yr over the 20th century. This new study shows that the rise between 1901-1990 was closer to 1.2 mm/yr. But there is strong consensus in the scientific community that the sea-level rise since 1990 has been about 3 mm/yr. What this means is that there has been a larger acceleration of global sea level than previously thought.
At last count, there were 209 articles regarding this fable.

“Another concern with this is that many efforts to project sea-level change into the future use estimates of sea level over the time period from 1900 to 1990,” said Eric Morrow, a recent Ph.D. graduate of the department of Earth and Planetary Sciences at Harvard. “If we’ve been overestimating the sea-level change during that period, it means that these models are not calibrated appropriately, and that calls into question the accuracy of projections out to the end of the 21st century.”
I’m sure you’ve noticed the words in bold: nothing within the articles suggest anything so pedestrian, oh, and scientific, like taking actual measurements. Estimates, projections, and, of course, the ever-present computer models. If you peruse the data via NOAA, you can see that individual charts do not show any sort of acceleration. In fact, many data points actually show a decrease in sea height, particularly in the very northern latitudes along the Alaska, Canadian, Scandinavian, and Russian coasts. The most northern measurement has Barentsburg, Norway, and island well north of Norway, as -2.25mm year. Strange. One would think that with all the supposed melting ice in the Arctic that the seas would rise quicker there.
Regardless, what Warmists are pushing is supposition, not science, and, even if there was an acceleration, it in no way proves anthropogenic causation.
NOAA and NASA reported today that 2014 was the warmest year recorded, and without an El Nino.

You misspoke here, as you certainly realize that melting sea ice has little impact on sea level. Melting ice cubes don’t increase tea level measurably in your iced tea. The melting terrestrial ice sheets of Antarctica and Greenland are adding to sea level.
Remember too that our Earth is a giant centrifuge, whose rotational force is forcing water to the equator. In fact, if the Earth were to stop spinning (it won’t!) we would be left with northern and southern oceans with a huge swath of land from the equator to thousands of miles north and south! Unfortunately, Canada, Europe and Russia would be underwater, but on the bright side you could bicycle to Hawaii or Africa!

Anyway, relative sea level changes are not uniform with regard to location.
No Jeff, you are wrong, except for the fact you actually know about the rotation of the earth and its effects (I am amazed). I agree with Teach, why do we have to read or rely on estimates. You simply stick a pole in the ocean and read the results, no big deal.
Only the mist vulnerable are doomed Teach so laugh it up
