A Reexamination of Climate Change Issues

Scientific Realities of the Greenland Ice Sheet

 November 18, 2009


Two scientific papers published by the website "ScienceMag.org" explain how ice builds in the center of large bodies of ice such as Greenland as it melts around the edges, as well as showing that ice fluctuations have been relatively constant in Greenland over the past 17 years.



ScienceMag.org - ”Recent Ice Sheet Growth in the Interior of Greenland”

This excerpt from an October 2005 scientific paper posted on ScienceMag.org shows the ice buildup in the interior of Greenland has been about 5.4 cm per year over 11 years.


"A continuous data set of Greenland Ice Sheet altimeter height from European Remote Sensing satellites (ERS-1 and ERS-2), 1992 to 2003, has been analyzed. An increase of 6.4 ± 0.2 centimeters per year (cm/year) is found in the vast interior areas above 1500 meters, in contrast to previous reports of high-elevation balance. Below 1500 meters, the elevation-change rate is -2.0 ± 0.9 cm/year, in qualitative agreement with reported thinning in the ice-sheet margins. Averaged over the study area, the increase is 5.4 ± 0.2 cm/year, or ~60 cm over 11 years, or ~54 cm when corrected for isostatic uplift. Winter elevation changes are shown to be linked to the North Atlantic Oscillation."
