SPATIALLY AND SEASONALLY-SPECIFIC RESPONSES TO FORCING AS DETECTED IN PALEOCLIMATE RECONSTRUCTIONS OF PAST CENTURIES

MANN, Michael E., Dept Environmental Sciences, Univ. of Virginia, Charlottesville, VA 22903, mann@Virginia.EDU

I will review recent progress in proxy-based reconstruction and modeling of climate changes in past centuries. Seasonally and spatially-resolved empirical surface temperature reconstructions of past centuries will be discussed, with an emphasis on the seasonal and spatial details of estimated changes. These details will be discussed and interpreted in the context of the modeled seasonal and regional response to estimated radiative forcing changes in past centuries. The likely role of radiatively forced changes in the NAO and the El Nino/Southern Oscillation will be discussed.
