1. Andreas Fischer, Mark Liniger
CH2018 – Workshop Welcome
Andreas Fischer, Mark Liniger
CH2018-Workshop, 2 July 2015

2. Heatwave 2015
Intensivste jährliche 14-tägige Hitzeperiode mit einem mittleren Tagesmaximum von 30 Grad oder mehr. Messstandort Genève 1864–2014. Verwendet wurden homogene Tagesmaximum-Temperaturen.

3. CH2018 Runs as Themenschwerpunkt in the framework of NCCS
NCCS is in the course of foundation
Addtional NCCS-Themenschwerpunkt will be CH2018-Hydro (coordinated by BAFU)
In CH2018 so far:  3 plenary meetings  meeting on application of Bayes Algorithm in CH2018

4. CH2018: Vision Consistency In method, data, communication
Consolidation
Mutually agreed on between scientists, single voice
Robustness
not necessarily latest research, but published, tested
Comprehensiveness
Target various sectors, different backgrounds
Sustainability
Associated services beyond report, framework for extensions

5. Aim of this workshop
Bring together the scientists working on CH2018-contributions
Agree on a technical/methodological flow in CH2018
Setup topical working groups to proceed with the next steps
Important metrics
Feasibility:
scientific limits. who? When? Resources?
Comprehensiveness:
what is missing? Critical issues? Coverage of past climate? Who/what depends on what? Gaps we can tolerate?
Consistency:
will results be consistent? What consistency do we want?

6. Market Research
… has started

7. Purpose of the Scenarios
User perspective
produce raw data with models
focus of «user needs»
Meteo-Schweiz
provide data, analyse and display climate data
deduce impacts for Switzerland for different scenarios
climate impact research
need for action: mitigation
need for action: adaptation
media
associations, unions
deduce adaptation measures
Confederation & Cantons
promote adaptation measures
others
implement adaptation measures
Purpose of the Scenarios
demonstrate need for mitigation action
demonstrate need for adaptation and basis for better adaptation

8. Market Research: Next Steps
Start with group interviews August
End of interviews early November
Workshop on user-centred design end October
Consolidation of market research at ProClim Symposium 20 November
Final report January 2016
