Max-Planck-Institute for Meteorology: Geoengineering and climate engineering

“Geoengineering” or “climate engineering” refers to various ideas to mitigate the greenhouse effect through technological solutions. With the help of climate models, researchers are investigating two strategies: The first is Carbon Dioxide Removal, or CDR. The second method is called Solar Radiation Management, or SRM.

In this video, Dr. Ulrike Niemeier from the Max Planck Institute for Meteorology explains the Earth's radiation budget and methods of SRM. Would such SRM methods be implementable in reality at all, and what would be the negative consequences?

Geoengineering also poses ethical and legal challenges to humanity. Who determines the temperature on Earth? Dr. Tom Sparks, Senior Research Fellow at the Max Planck Institute for Comparative Public Law and International Law, answers these questions. (Only in German)
