In 1981, experts blamed loss of Antarctic sea ice on global warming
EVIDENCE IS FOUND OF WARMING TREND

To measure possible changes around the Antarctic ice pack, where ground stations are sparse, the Columbia team compared recent satellite photographs of the extent of the ice pack with old Soviet and American atlases and with whaling ship reports from 1929 to 1934.
They found that the typical summer ice pack had decreased about 35 percent, by 2.5 million square kilometers, or about 1 million square miles from 1973 to 1980. The Antarctic ice cover was also found to be considerably lighter than shown in atlases published in 1957 and 1966 and in the ship reports from the 1930’s. This was taken as an indirect measure of higher temperatures.
‘‘It is just where we expected it from the theory, it fits nicely,” he added. While he said this gives ”much stronger support” to the greenhouse theory
In 2015, experts say that increasing Antarctic sea ice is due to global warming
It seems weird, but like this winter’s epic polar vortex outbreaks in North America, this week’s record-breaking Antarctic sea ice could be a further sign of global warming.
If Antarctic sea ice wasn’t changing, that would also be due to global warming.
