Spread in the magnitude of climate model interdecadal global temperature variability traced to disagreements over high-latitude oceans.

ABSTRACT: Unforced variability in global mean surface air temperature can obscure or exaggerate global warming on interdecadal timescales, thus understanding both the magnitude and generating mechanisms of such variability is of critical importance for both attribution studies as well as decadal climate prediction. Coupled atmosphere-ocean general circulation models (climate models) simulate a wide range of magnitudes of unforced interdecadal variability in global mean surface air temperature (UIT_global), hampering efforts to quantify the influence of UIT_global on contemporary global temperature trends. Recently, a preliminary consensus has emerged that unforced interdecadal variability in local surface temperatures (UIT_local) over the tropical Pacific Ocean are part
