The atmospheric circulation response seems to be sensitive to the magnitude and geographic pattern of sea - ice loss and, in some cases, to the background climate state. (nature.com)
The influence of changing ocean currents on climate change is evaluated by comparing an earth system model's response to increased CO2 with and without an ocean circulation response. (gfdl.noaa.gov)
It is especially challenging with regard to the local / regional circulation response to global warming. (pnnl.gov)
