A report posted by the National Snow & Ice Data Center NSIDC on October 7 stated: “Sea ice in Antarctica has remained at satellite-era record high daily levels for most of 2014.”The report noted that during the period between September 10 and September 22 very rapid late-season ice growth in Antarctica pushed the total sea ice extent upward by nearly 23,000 square miles per day. This was the first time since 1979 that Antarctic sea ice extent exceeded 20 million square kilometers 7.7 million square miles.As to what this means, Ted Scambos, lead scientist at the NSIDC stated: “What we’re learning is, we have more to learn.” NSIDC researchers have not immediately assumed that the increase in Antarctic ice is an indication that popular “global warming” theories are incorrect, however. They, instead, offer other explanations, such as “wind patterns” and that “recent ice sheet melt, caused by warmer, deep ocean water reaching the coastline and melting deeper ice, is making the surface water slightly less dense. While the change in saltiness is too small to significantly affect the freezing temperature, the increase in slightly less dense water surrounding Antarctica inhibits mixing, creating conditions that favor ice growth.”In other words, this explanation goes, melting ice creates “slightly” less dense water, which, in turn, has been responsible for a significant growth of ice that has been going on for 35 years! The trend has accelerated recently. As an October 7 NASA report puts it: “So in just 13 days, 299,000 square miles of open ocean became covered in floating ice — an area larger than Texas!” That seems like a lot of ice caused by “slightly” less dense water.An article about these latest findings in the U.K.-based The Register noted that the increase in Antarctic ice has created confusion in the minds of many scientists, who find it difficult to reconcile with their preconceived views on “global warming.” The report stated:Climate scientists have been puzzled by the behaviour of the southern ice for many years now. The most commonly used models say that its steady growth should not be happening in a warming world though the warming of the world is also in doubt, as air temperatures have been steady for the last fifteen years or more — and it turns out that deep ocean temperatures are not increasing either, leaving the “mystery” of the apparent end of global warming “unsolved.”
