According to the National Snow and Ice Data Center (nsidc.org), ice currently covers 6 million square miles, or one tenth the Land area on Earth, about the area of South America. Floating ice, or Sea Ice, alternately called Pack Ice at the North and South Poles covers 6% of the ocean’s surface (nsidc.org), an area similar to North America. The most important measure of ice is its thickness. The United States Geologic Survey estimates the total ice on Earth weighs 28 million Gigatons(a billion tons). Antarctica and Greenland combined represent 99% of all ice on Earth. The remaining one per cent is in glaciers, ice sheets and sea ice. Antarctica can exceed 3 miles in thickness and Greenland one mile. If they were to melt sea level would indeed rise over 200 feet, but not even the most radical alarmists suggest that possibility arising due to the use of fossil fuels. However the ice that flows off of the Antarctic and Greenland called shelf ice represents only half a percent of all the Earth’s ice and which if melted would raise sea level only 14 inches, (nsidc.com).

A warming trend of 0.32 °C/decade during 1979–1997 to a cooling trend of − 0.47 °C/decade during 1999–2014.
Remember the much ballyhooed paper that made the cover of Nature, Steig et al, “Warming of the Antarctic ice-sheet surface since the 1957 International Geophysical Year”, Nature, Jan 22, 2009 that included some conspicuously errant Mannian math from the master of making trends out of noisy data himself? Well, that just went south, literally.
