Not exact matches

Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.

Indeed, the dampened late 20th century winter warming over a substantial part of Greenland, particularly the western and southern regions emphasized by the network of stations analyzed by Vinther et al, is known (see e.g. this NOAA page) to be associated with a trend toward the positive phase of the Arctic Oscillation («AO») pattern.

To clarify my above comment, I was suggesting that the observed rise in ocean heat content would be substantial with or without the La Nina effect, representing primarily the persistence of a long term warming trend.

Apparently, after taking into account the effects of the NAO, there's a substantial underlying warming trend.

The antarctic ice winter max decreased by about one third during this period, and the HadCRUT temp data base for that region during that period does show a substantial surface air temperature warming trend.

The second issue raised in our Science paper (now available free, see bottom of this post) is that perhaps there shouldn't yet have been substantial long - term trends in hurricane intensity — whether we would be able detect them above the natural variability or not — because until the last couple of decades, aerosol cooling effects on hurricanes have been counteracting the effects of greenhouse gas warming.

Even the OLS trend over the last 16 years is positive and the uncertainty range covers substantial warming.

The very high significance levels of model — observation discrepancies in LT and MT trends that were obtained in some studies (e.g., Douglass et al., 2008; McKitrick et al., 2010) thus arose to a substantial degree from using the standard error of the model ensemble mean as a measure of uncertainty, instead of the ensemble standard deviation or some other appropriate measure for uncertainty arising from internal climate variability... Nevertheless, almost all model ensemble members show a warming trend in both LT and MT larger than observational estimates (McKitrick et al., 2010; Po - Chedley and Fu, 2012; Santer et al., 2013).
