November 7th: Peter HUYBERS Harvard University On the supposed inter-hemispheric symmetry of climate at orbital time-scales

Add to my calendar (ics file)

The approximate interhemispheric symmetry of orbital-scale glacial variability is generally credited to Northern forcing of Southern changes, but which is difficult to reconcile with, among others, observations that Southern climate is nearly coincident with Northern changes. Mercer called this “the fly in the ointment of Milankovitch theory”. Instead, I’ll argue that … Check the full abtract here

November 14th: Arne WINGUTH University of Wisconsin/Madison The sensitivity of the marine carbon cycle to long-term climatic changes	Add to my calendar (ics file)
An ocean carbon cycle model is used evaluate the role of climate-induced changes of the carbon cycle for the oceanic pCO2. Single contributing terms for the total change in pCO2, including the temperature effect and non-temperature effects (DIC, ALK, S), are analyzed. For this purpose, an adjoint carbon cycle model … Check the full abstract here
