Within the IMAU colloquium series a special series is embedded called “Hot Topics in Climate”. This year the series will be devoted to the carbon cycle and geo-engineering.

In this series we start with a ca 15-minute introduction by an international expert on the topic, which can be a bit provocative emphasizing points where scientists still disagree, or where the science is still controversial, followed by ca 45 minutes of open discussion.

Dr. David Keller (GEOMAR Helmholz Centre for Ocean Research Kiel) is project leader of the Carbon Dioxide Removal Model Intercomparison Project (CDRMIP) and an EU Horizon 2020 project on negative emissions technologies, OceanNETs (). His main interest is in Climate Engineering through ocean-based approaches of carbon dioxide removal. In COP21 the need of negative emissions or CDR was recognised to be essential to limit global warming to less than 2°C.  In response to COP21 the CDRMIP and OceanNETs projects were created to examine how the climate and Earth system respond to carbon dioxide removal approaches like bioenergy and carbon capture and storage which underpins proposed low-carbon pathways to meet the target of less than 2°C global warming. In the Hot Topic Seminar of March 30th David will discuss results of CDRMIP and OceanNETs with an emphasis on ocean-based approaches such as increasing the alkalinity of the World Ocean.
