TL;DR: The recent U.S. National Academies report, Assessment of Intraseasonal to Interannual Climate Prediction and Predictability, was unequivocal in recommending the need for the development of a North American Multimodel Ensemble (NMME) operational predictive capability.

TL;DR: In this paper, the second-generation Canadian earth system model (CanESM2) was used to assess the response of the second generation earth system models to historical (1850-2005) and future (2006-2100) natural and anthropogenic forcing.

TL;DR: The second phase of the Global Land-Atmosphere Coupling Experiment (GLACE-2) is aimed at quantifying, with a suite of long-range forecast systems, the degree to which realistic land surface initialization contributes to the skill of subseasonal precipitation and air temperature forecasts.

TL;DR: The second phase of the Global Land-Atmosphere Coupling Experiment (GLACE-2) is a multi-institutional numerical modeling experiment focused on quantifying, for boreal summer, the subseasonal forecast skill for precipitation and air temperature that can be derived from the realistic initialization of land surface states, notably soil moisture as mentioned in this paper.

TL;DR: A sound and coordinated framework for verification of decadal hindcast experiments and provides guidance on the use of these model predictions, which differ in fundamental ways from the climate change projections that much of the community has become familiar with.
