Sentences with phrase «levels over the past millennia»
The reconstructed changes in sea level over the past millennium are consistent with past global temperatures, the researchers say, and can be determined using a model relating the rate of sea level rise to global temperature.

That estimate was based in part on the fact that sea level is now rising 3.2 mm / yr (3.2 m / millennium)[57], an order of magnitude faster than the rate during the prior several thousand years, with rapid change of ice sheet mass balance over the past few decades [23] and Greenland and Antarctica now losing mass at accelerating rates [23]--[24].
============================= Says Steve McIntyre, commenting on the new sea level reconstruction paper by Kemp et al at PNAS, «Climate Related sea - level variations over the past two millennia»:
Kemp, A. C., B. P. Horton, J. P. Donnelly, M. E. Mann, M. Vermeer, and S. Rahmstorf, 2011: Climate related sea - level variations over the past two millennia.
«It is exceptionally unlikely that we would be seeing a record year, during a record warm decade, during a multi-decadal period of warmth that appears to be unrivaled over at least the past millennium — if it were not for the rising levels of planet - warming gases produced by fossil fuel burning.»

Except and unless you accept the premise that all observations are completely useless because someone is able to quibble over their details, follow through the math, compare with the original works, and you still come up with much too little error to account for the 22 % -25 % differences seen over the past quarter millennium and the maximum CO2 level measured in the past 60K - 85K years and extrapolated for the past 10 - 15 million years.
«Having a detailed picture of rates of sea level change over the past two millennia provides an important context for understanding current and potential future changes,» says Paul Cutler, program director in NSF's Division of Earth Sciences.
