4 From science to decisions

5 Researcher/User -dialogue User: What about this climate change?

6 Researcher/User -dialogue Scientist: What do you want to know?

7 Researcher/User -dialogue User: You know, about temperature.

8 Researcher/User -dialogue Scientist: Average, max, min, variability,?

9 Researcher/User -dialogue User: You tell me!

10 One Users can use information, if prepared properly Scientific knowledge AND users knowledge

11 Two Scientific articles are not a good way across But necessary for defining the base line knowledge Adds credibility when scientific excellence is documented Talks and seminars Briefs Proof reading Reference groups National Authorities cooperation Personal involvement and interaction

excellence is documented Talks and seminars Briefs Proof reading

12 Three There is uncertainty There is information It s about the impacts

13 Four you Internal dialogue Key persons External demands change Collaborate, broadly

15 CRES Objectives extend knowledge of and reduce the uncertainties surrounding regional climate change and its impacts support future climate change adaptation and mitigation policies, targeting Danish and wider regional needs. assist enhancing the knowledge base and direct advisory capacity for Danish actors, including government and the private sector

policies, targeting Danish and wider regional needs.

22 How reliable are our sea level rise projections? Observed sea level rise tends to follow the uppermost dashed line of the IPCC scenarios, namely the one "including land ice uncertainty IPCC models underpredict rates of sea level rise by ~40% (Rahmstorf et al., 2007). Comparison of the 2001 IPCC sea-level scenarios (starting in 1990) and observed data. Church and White (2006) data based primarily on tide gauges (annual, red) and the satellite altimeter data (updated from Cazenave and Nerem 2004, 3-month data spacing, blue, up to mid-2006) are shown with their trend lines.

31 Symposium on high-end scenarios and impacts 26 Nov 2012 Eigtveds Pakhus from Registration on cres-centre.net The purpose of the symposium is to highlight some of the possible impacts for Denmark when changes in the global average temperature by far exceeds 2C and highlight the current needs for additional research to support a proper risk assessment and help reduce the considerable uncertainties.
