While the media, environmentalists, and certain politicians have been having a field day with the notion that the Antarctic ice caps are melting at an alarming rate due to manmade global warming, it turns out that there is little evidence to support any of the arguments given to support that notion, or that the ice caps are even melting.
NASA scientist Eric Rignot stated that increased melting had been detected in the ice sheets of western Antarctica. He then hypothesized that the cause may be the flow of warmer waters from the Antarctic Circumpolar Current that circles much of the continent, and believed that man was the reason for it.
According to the facts, though, temperature analysis from each of eight NASA stations located in Antarctica actually shows that western Antarctica is actually getting cooler.
Columbia University’s Douglas Martinson backed up Rignot’s hypothesis by saying that the [Antarctic Circumpolar Current”, which flows about 200 yards below the frigid surface water, began to warm significantly in the 1980s, and that warming in turn caused wind patterns to change in ways that ultimately brought more warm water to shore.”
He also admitted that there wasn’t enough data to say for sure that the process was set in by global warming. According to a World Climate Report published in 2007, “below-surface ocean temperature data are sparse, and the existing data sets involve substantial ‘interpolation, extrapolation, and averaging’ that may compromise the integrity of results from such data sets.”
An IPCC report stated that the ocean temperatures near Western Antarctica warmed 1 degree Celsius from 1951 to 1994. Global surface temperatures, however, declined from 1940 to 1976, at a time when carbon dioxide emissions dramatically increased.
“The bottom line is there is no established linkage between manmade emissions of greenhouse gases and any melting in the western Antarctic.”- JunkScience.com
