"Exploring Global Warming with Climate Models of Various Complexity"
by Syukuro Manabe (Princeton University)
Dr. Manabe is a Senior Meteorologist at Princeton University, and one of the world’s leading scientists in numerical modeling of climate and climate change. For more than five decades Dr. Manabe worked at the Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey, where he pioneered the use of computers to simulate global climate change and natural climate variations. These breakthroughs have helped provide the foundation...
Global mean temperature has risen for the past century and is projected to rise even more in response to the increasing atmospheric CO2 concentrations. Precipitation change is of vital importance to societies but precipitation projections are intrinsically challenging as they change sign from one region to another. Recent studies show that in the tropics,...
This talk will highlight the relative importance of internally-generated vs. externally-forced climate trends at local and regional scales over North America and Eurasia based on a 30-member ensemble of the Community Earth System Model over the period 1920-2100. Each member is subject to the same historical and future (RCP8.5) radiative forcing scenario, but starts from a slightly different atmospheric state. Unpredictable,...
We argue for a pervasive link between cold climates and polar ocean stratification. In both the Subarctic North Pacific and the Antarctic Zone of the Southern Ocean, ice ages were marked by low productivity. The accumulated evidence from sediment cores points to an increase in density stratification that reduced the supply of...
