With the Paris agreement, a majority of the world’s countries have agreed to keep anthropogenic warming below 2oC. According to the Intergovernmental Panel on Climate Change, this target would require not only reducing all man-made greenhouse gas emissions to zero but also removal of large amounts of carbon dioxide from the atmosphere, or other type of geo-engineering techniques. The issue of geo-engineering has been heavily debated during the last years and we are therefore asking: Are the potential risks with geo-engineering sufficiently known? Are safe geo-engineering techniques available? Are they available now?

This debate will address these questions of crucial importance for today’s society. It will discuss the most recent discoveries of geo-engineering techniques, their potential to reduce global warming and their potential risks.
