The 3rd DLR conference on Climate Change (CCC 2020) will take place at the Flora in Cologne, Am Botanischen Garten 1a 50735 Cologne/ Germany on 28-30 April 2020. We are looking forward to welcome you in Cologne in April 2020!

A short overview of the topics for CCC 2020 – Climate Research in the light of the Paris Agreement in collaboration with the United Nations Office for Outer Space Affairs (UNOOSA) is given below.

Understanding Climate Change is the most important scientific as well as social challenge of this century. Climate Change is a change on a systems level. To combat Climate Change clearly needs Earth Observation and Remote Sensing via satellites. Issues of aviation, transport, energy management and artificial intelligence are strongly needed either. All of these research fields are tackled by the German Aerospace Center.

This time we will be concentrating on developing ideas for specific steps to take concerning mitigation and adapting climate change influences. Again, prominent international scientists, space agencies and interested parties together with representation from the United Nations such as UNOOSA, UNSPIDER, UNFCCC, WMO and GCOS will be joining force to exchange ideas and intensify our joint knowledge of the effects of climate change. The aim is to provide a concrete basis for the implementation of suitable counter measures which can be adopted by governmental and non-governmental entities.
