As the concentration of greenhouse gas increases in the atmosphere, temperature increases at the earth surface. In the Northern Hemisphere, the magnitude of the warming increases with increasing latitude and is at a maximum over the Arctic Ocean and its immediate vicinity. In the Southern Hemisphere, on the other hand, the polar amplification of the global warming is absent in the Antarctic Ocean. This is what happened in the numerical experiment conducted at GFDL almost 30 years ago. The geographical pattern of global warming described above appears to be broadly consistent with the pattern of surface temperature change that have been observed during the last several decades, when the rate of increase of greenhouse gas is pronounced. In this talk, I would like to discuss the role of ocean in delaying global warming particularly in the circumpolar ocean of the Southern Hemisphere.
