Scientists said that the arctic ice is at its second lowest level in the past 30 years or since the satellite records began.
Experts from the National Snow and Ice Data Center (NSIDC) said the latest data shows that the arctic ice is now bellow the 2005 level and that the melting process started earlier this year. This means that it might reach its lowest recorded level in September despite the fact that this year’s temperatures have been lower compared to last year, NSIDC scientists explained.
Ice in the Arctic Ocean is at a climatic "tipping point," as the experts put it. The arctic ice now covers 2.03 million square miles (5.26 million sq km). The lowest level ever was recorded last September when the arctic ice was covering about 1.65 million square miles. Most of that is thin ice which formed during the past year and melts faster.
Just a few years ago, scientist predicted that by 2080 all the Arctic ice will melt during summer. However, the computer models revealed the fact that this could happen much earlier, around 2030 to 2050.
"We could very well be in that quick slide downward in terms of passing a tipping point," said Mark Serreze, senior scientist at the NSIDC.
"It's tipping now. We're seeing it happen now."
According to NASA ice scientist Jay Zwally, if the accelerated melting process continues, within "five to less than 10 years," the Arctic Circle will be ice-free during the summer period.
"It means that climate warming is also coming larger and faster than the models are predicting and nobody's really taken into account that change yet," Zwally said.
