Stroeve explains that highly reliable data on the extent of Arctic sea ice has been collected since 1978. From then until now, she has found clear evidence of a 30-year melting trend, which, she says, “cannot be easily explained away by natural variability.” But her work is even more notable for its findings about the speed of the change. Over this same 30 years, a relatively brief period, Stroeve has found that some 40 percent of the region’s summer (or more precisely, September) ice has melted.

I disagree. There is a clear relationship between PDO/ENSO and Arctic Ice.
We know that temperatures in Alaska are closely correlated with PDO/ENSO. Wouldn’t we expect western Arctic ice to be similarly affected?
