Climate change - ?
Change of the air temperature compared with period 1961 to 1990 in Germany. The corridors (orange: A1B and A2, green: B1) represent theaverage of 10 WETTREG simulations and the REMO run. The grey areaindicates the overall span of all three emission szenarios (Federal Environmental Agency of Germany UBA, October 2006).
