Atmopshereic Physicist Dr. Fred Singer reacts to media touted Greenland/Antarctic ice study
Number of the Week: 55.5 mm or 2.2 inches per century. The international research group of polar scientists, IMBIE, announced that melting glacial ice on Greenland and Antarctica has increased sea levels by 11.1 mm over 20 years, from 1992 to 2011, which can be extrapolated to the numbers above. However, one must not rely on long run extrapolations from short run data.
Yet, IMBIE did so. It stated that sea level rise increased in the second decade over the first decade. What is particularly interesting is the early data shows a decline in sea levels from an accumulation of ice, which indicates a cooling. Yet the 1980s and 1990s were decades of warming.
Further, there has been no surface warming for about 15 years. This indicates that the ice melt does reflect current temperatures, and other factors must be involved. If ice melt constitutes 30% of the sea level rise as the article suggests, then the 21 st century increase will be at the low end of the range suggested by the IPCC, which is consistent with Fred Singer’s suggestions, and far from Jim Hansen’s predictions.
It is also interesting that news reports, such as in the Washington Post, excitedly reported the polar melt and sea level rise, but failed to provide information on how tiny the rise is.

Media touted model driven study exposed: ‘New Ice Surveys Finds Slower Ice-sheet Melting’ — ‘E. Antarctic Ice Sheet — over 75% of Antarctica, experienced mass gains during final years of study’
Excerpted Analysis — For Doug L. Hoffman’s complete analysis see here:
The good news, according to Riva, is that Antarctica is not losing ice as rapidly as suggested by many recent studies. Moreover, snowfall in east Antarctica seems to be compensating for some—if not quite all—of the melting elsewhere in Antarctica’

For Greenland things are a bit murkier. “Assessments of GrIS mass balance require more careful consideration than was possible here, because the surrounding mountain glaciers and ice caps are included in some, but not all, of our geodetic surveys and because the ice-sheet domains varied in area by 2%,” explain Shepherd et al..
It is unclear how these trends, such as ice loss from Greenland, will evolve, says Ian Joughin, one of the paper’s co-authors and a satellite expert at the University of Washington in Seattle: “It really remains unclear whether such losses will decline, whether they’ll level off or they’ll accelerate further.” This should be viewed in light of recent data that show Greenland underwent a similar episode of ice loss in the 1930s.
Indeed, Shepherd et al. admit that their work is biased on too short a time span to draw any meaningful long-term conclusions. “We have shown that assessments of mass imbalance based on short geodetic records should be treated with care, because fluctuations in SMB can be large over short time periods,” they admit, hinting at the study’s fundamental problem. Recent ice-core data reveal that theAntarctic Peninsula area undergoes bouts of rapid warming periodically.
It is striking that supporters of calamitous climate change always base their projections on the last three decades or so—a period that was, in fact, a time of increasing warmth. In this case, they found melting ice around the globe, just not as much as often claimed and certainly not justification for projections into the future for 50 or 100 years. Go back 150 years and people were not worried about retreating glaciers but advancing ones.
