Enhanced variability on decadal to multidecadal timescales occurs over a number of regions of the world (e.g., Tropical Pacific, North Pacific, and North Atlantic). Understanding the mechanisms for this variability and to what extent it is predictable are important, both because of the economic and socioeconomic consequences, and to improve detection and attribution of anthropogenic forcing of climate change. There have been a number of important developments in the last few years. Especially, the PREDICATE project has shown in a comparison of several coupled general circulation models that North Atlantic climate could be predicted at least a decade in advance. There is even research underway into the development of prediction systems. Here we review the recent progress in decadal and multidecadal climate predictability.
