Nope, I mean the arctic ice.A report in the July issue " Journal of Climate" shows that errors in an earlier study created the misimpression that Arctic ice was thinning. An abstract from the Journal of Climate reads: "Reports based on submarine sonar data have suggested Arctic sea ice has thinned nearly by half in recent decades. Such rapid thinning is a concern for detection of global change and for Arctic regional impacts. Including atmospheric time series, ocean currents and river runoff into an ocean–ice–snow model show that the inferred rapid thinning was unlikely. The problem stems from under sampling. Varying winds that readily redistribute Arctic ice create a recurring pattern whereby ice shifts between the central Arctic and peripheral regions, especially in the Canadian sector. Timing and tracks of the submarine surveys missed this dominant mode of variability. Although model-derived overall thinning from the 1960s to the 1990s was less than hitherto supposed, there is also indication of accelerated thinning during the early–mid-1990s" In the authors words, "the volume estimated in 2000 is close to the volume estimated in 1950."Though the earlier flawed study received wide coverage by the media this latest study has been largely ignored.
