The bottom could be in for Arctic sea ice this year which will make it the third lowest in the last 30 years.

However, in Anchorage, Alaska, the local fish wrap would have you believe the trend the sky is falling.

From the

“A report shows this summer’s Arctic sea ice melted to the third-lowest level since satellite monitoring began in 1979, continuing a trend of habitat loss for walrus, polar bears and other ice-dependent marine mammals.”

“Brendan Cummings, an attorney for the Center for Biological Diversity, said the announcement illustrated a trend for summer Arctic sea ice and means bad news for walrus.
‘We’re on a clear path to a seasonal ice-free Arctic,” he said. “There may be year-to-year fluctuations, but the clear path is unidirectional.’”

Yes, the overall trend for the past 30 years shows a downward trajectory. However, the temperature in the arctic is already below freezing (below) and this sure looks like we survived this summer with a greater amount of sea ice than the year before. I see that as a positive sign and remain optimistic that we are headed for recovery!
