Coverage of ice in Antarctica is the largest of the last 40 years

Since 1970 the ice of Antarctica not covered an expanse as large, according to NASA. And although many use this information to deny global warming, the truth is that NASA says that this phenomenon exists â€" exactly â€" due to the planet's climate imbalance.

According to researchers, this gain of ice at the South Pole may have a direct relationship with the temperature increase on Earth, which would have caused the movement of colder air to the region. "Without any geographic barrier to the North, ice can expand freely if show favorable conditions," said Walt Meier, a scientist at NASA.

Another possible cause for the growth of glacial coverage is the low-pressure system from the sea Amundsen, in the Antarctic Ocean, which has been showing changes, leading more wind to the Mainland.

The sustainable planet advances several hypotheses are being raised to explain this new record. What is known so far though is that while the melting in the Arctic keeps growing â€" are lost on average 20 thousand square metres of ice per year, Antarctica gets more coverage.
