Pointing Science: Climate Engineering - Views Onto a Man-Made Climate 

SPP 1689 Climate Engineering Research Conference 2015

Public Event – July 9 • 19:00 h • Berlin Akademie der Wissenschaften

On thursday evening we invite you to take part in our 'Pointing science' knowledge show 'Climate Engineering • Views Onto a Man-Made Climate' . Pointing science is a media-based show, in which experts as well as the audience are able to participate. The direction of the discussion is determined by the audience, who votes for topics using laser pointers. The combination of scientific expertise, entertaining elements and an active audience enables a lively transfer of complex and diverse knowledge.
In preparation to the show experts and laymen were interviewed on different aspects of climate engineering. These interviews were then edited to small video clips, which are offered on a screen for voting during the show and present a broad spectrum of perspectives. In addition, life comments from experts on stage or contributions from the audience via microphone, SMS or twitter will be offered. However, who is going to contribute is determined by the audience. This format enables a lively, self-organized and democratic discussion on a complex topic, such as Climate Engineering.

Developer and producer of the show are Tobias Hülswitt and Gunther Kreis who successfully used this format with other complex and controversial topics.

clips in English • discussions / questions also in German possible

"The novelty of our research relies on the fact that none of previous studies have addressed this topic with a fully coupled Earth system model of such a level of complexity. Fully coupled set-ups (versus box-models or forced subsystems) hold the potential of revealing new features within the Earth system dynamics."

Niemeier, U.; Timmreck, C. (2015): What is the limit of stratospheric sulfur climate engineering?
"The injection of sulfur dioxide (SO2) into the stratosphere to form an artificial stratospheric aerosol layer is considered as an option for solar radiation management. The related reduction in radiative forcing depends upon the amount injected of sulfur dioxide but aerosol model studies indicate a decrease in forcing efficiency with increasing injection magnitude."
