1 ASSESSMENT OF HEALTH RISKS FROM ALLERGENIC PLANTS, ANIMALS ANDVECTOR BORNE DISEASES IN RHINELAND PALATINATE UNDER CLIMATE CHANGE CONDITIONS Dr. Astrid Kleber Rhineland Palatinate Centre of Excellence for Climate Change Impacts

2 Climate change in Rhineland Palatinate Temperature since K C

3 Climate change in Rhineland Palatinate Long term averages ofthe airtemperature Mean air temperature [ C]

4 Climate change in Rhineland Palatinate Temperature projections 2 6 K

5 Climate change in Rhineland Palatinate Precipitation since 1881 slight increase

6 Climate change in Rhineland Palatinate Precipitation projections summer tendency unclear winter increase is likely
