SPP 1689 Workshop Terrestrial CO2 Removal

SPP 1689 WORKSHOP // 22 – 23 Jan 2018 // Potsdam Institute for Climate Impact Research, A56

Terrestrial CO₂ Removal: Potentials and tradeoffs in the SDG context

This workshop will look into a set of pertinent questions related to potentials of tCDR methods and their interaction with SDGs. It will bring together SPP 1689 researchers and external experts to increase our holistic understanding of global and regional potentials and side-effects of tCDR as well as to identify future research priorities.

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."

Climate CoLab

MIT (Massachusetts Institute of Technology) Center for Collective Intelligence has just launched its Climate CoLab for 2014. (climatecolab.org)

This year it includes a contest where participants can propose a solution to the question: "How can research into geoengineering be governed to limit its environmental and political risks?"
