Prof. Dr. Hubertus Fischer

Paleoclimate research using natural climate archives has become an integral part of climate science, providing information on the long-term response of the Earth System on Changes in the radiative balance of the globe and crucial benchmarks for climate models beyond the short direct observational record. Ice cores in particular have played a crucial role as they represent the only direct archive of the past atmospheric composition and provide the quantitative record of past variations in atmospheric greenhouse gas concentrations and their radiative forcing. However, ice cores have much more to offer. Using new analytical approaches in ice core research, they provide an integrative view on past changes in the Earth system including climate changes on the ice, atmospheric changes, changes on land and in the ocean. The talk will present some of the latest highlights in ice core research, discuss the theoretical background and limitations of the tracers used and direct the view to future ice core science projects.
