YCEI Speaker Series
Each academic year, the Yale Climate and Energy Institute organizes a series of lectures by visiting experts on a broad range of topics in climate and energy. Presentations for the coming year include:
11/03/2014 - 2:00pm | Deep Ocean Circulation in the North Atlantic and Rapid Climate Change During the Last Ice Age
Jerry McManus, Lamont-Doherty Earth Observatory
Rapid climate changes characterized the last ice age and deglaciation, with dramatic warming following the coldest intervals in the northern hemisphere. The repeated pattern of alternating temperature swings revealed in ice cores from Greenland and Antactica suggest a bipolar see-saw of heat redistribution by a dynamical component of the Earth system such as the large scale Atlantic Meridional Overturning Circulation (AMOC). Computer model simulations support this possibility, yet direct evidence for these changes in deep ocean circulation has been difficult to obtain.
12/01/2014 - 2:00pm | Jon Egill Kristjansson, University of Oslo
As global anthropogenic emissions of greenhouse gases continue to rise, there is an increasing risk of serious disruptions in ecosystems due to global warming. As a consequence, research on climate engineering (CE) is receiving growing attention, also among climate scientists. But, even basic CE research using Earth System Models (ESMs) raises a series of ethical questions that need to be considered. Also, CE carries a risk of serious side effects, e.g., concerning the hydrological cycle.
