Loss Of Arctic Ice Leaves Experts Stunned

Posted on Wednesday, September 05 at 16:19 by bracewell
An Arctic specialist at the US National Snow and Ice Data Centre, said that typical winter ice expansion would be difficult this year. “This summer we've got all this open water and added heat going into the ocean. That is going to make it much harder for the ice to grow back."

"If you asked me a couple of years ago when the Arctic could lose all of its ice then I would have said 2100, or 2070 maybe. But now I think that 2030 is a reasonable estimate. It seems that the Arctic is going to be a very different place within our lifetimes, and certainly within our childrens' lifetimes."

Dr Serreze said that even these pessimistic predictions may have overestimated the resilience of the Arctic sea ice. He said that we may have already reached the tipping point when there is a rapid disintegration. "The big question is whether we are already there or whether the tipping point is still 10 or 20 years in the future. My guts are telling me we may well be there now," Dr Serreze said.
