Using computer models with future global warming scenarios, Prof. Zhengyu Liu and an international team led by Prof. Jun Cheng from China recently published a paper on Proceedings of the National Academy of Sciences (PNAS). Their study suggests that interdecadal variability (i.e. variability of periods of several decades) of the Atlantic Meridional Overturning Circulation (AMOC) will be shortened and weakened under future global warming scenarios. They propose that the shortening of the variability is caused by the changing oceanic wave speed in response to global warming, which subsequently reduces the amplitude of the variability. The AMOC is a key ocean current that modulates global climate and this finding may have important implications for the future projection of climate and climate variability.

Dan Vimont was recently appointed co-chair of The Scientific Steering Committee (SSC). SSC directs the scientific and implementation planning of the program, setting the program goals, implementation strategies, and research challenges to be pursued. It is comprised of nine members with expertise spanning the breadth of the US CLIVAR agenda and diversity of representation. Dan holds this appointment through December, 2018.

In an article published in Nature Communications, Professor Tristan L'Ecuyer and colleagues at the University of Leuven find that clouds play an important role in the rate at which the Greenland ice sheet is losing mass. Using unique new satellite-based estimates of cloud structure, the group found that clouds may be responsible for a third of the meltwater runoff from the ice sheet by impeding refreezing of liquid water at night time. The results highlight the importance of improving the representation of Arctic clouds in climate models for accurately predicting future sea level rise.
