Updated NASA data is showing that “global warming” is not causing any type of polar ice retreat.
The ice caps have not receded one bit since NASA installed satellite instruments to measure the polar ice caps back in 1979. In fact, since 2012, the “total polar ice extent” is remaining “above the post-1979 average”. The data directly contradicts another myth of the left and global warming fanatics, this would be the myth that “due to global warming, the polar ice caps are melting”.
A piece by James Taylor for Forbes outlines the history of the NASA satellite instrument and the ways in which “global warming alarmists” manipulate data and information to their benefit:
The timing of the 1979 NASA satellite instrument launch could not have been better for global warming alarmists. The late 1970s marked the end of a 30-year cooling trend. As a result, the polar ice caps were quite likely more extensive than they had been since at least the 1920s. Nevertheless, this abnormally extensive 1979 polar ice extent would appear to be the “normal” baseline when comparing post-1979 polar ice extent.
Updated NASA satellite data show the polar ice caps remained at approximately their 1979 extent until the middle of the last decade. Beginning in 2005, however, polar ice modestly receded for several years. By 2012, polar sea ice had receded by approximately 10 percent from 1979 measurements. (Total polar ice area – factoring in both sea and land ice – had receded by much less than 10 percent, but alarmists focused on the sea ice loss as “proof” of a global warming crisis.)
A 10-percent decline in polar sea ice is not very remarkable, especially considering the 1979 baseline was abnormally high anyway. Regardless, global warming activists and a compliant news media frequently and vociferously claimed the modest polar ice cap retreat was a sign of impending catastrophe. Al Gore even predicted the Arctic ice cap could completely disappear by 2014.
