TL;DR: In this paper, the authors describe the development and evaluation of an Earth system model suitable for centennial-scale climate prediction, which includes terrestrial and ocean ecosystems and gas-phase tropospheric chemistry along with their coupled interactions.

TL;DR: In this paper, changes in the patterns of tropical precipitation and circulation are analyzed in Coupled Model Intercomparison Project phase 5 (CMIP5) GCMs under the representative concentration pathway 8.5 (RCP8.5) scenario.

TL;DR: The authors quantifies a direct link between global greenhouse gas emissions and rainfall changes over tropical land, and identifies regions most at risk of large changes, such as southern and east Africa, and shows that despite uncertainty in the location of future rainfall shifts, climate models consistently project that large rainfall changes will occur for a considerable proportion of tropical land over the twenty-first century.

TL;DR: In this paper, the authors show that much of the atmospheric blocking error diagnosed using common methods of analysis and current climate models is directly attributable to the climatological bias of the model, which explains a large proportion of diagnosed blocking error in models used in the recent Intergovernmental Panel for Climate Change report.

TL;DR: In this article, two particular systematic errors are examined: tropical circulation and precipitation distribution, and summer land surface temperature and moisture biases over Northern Hemisphere continental regions, each of these errors affects the model performance on time scales ranging from a few days to several decades.
