The South-German Climate Office is an interface between research and society, which supplies information on climate aspects in a competent and understandable manner. Work is based on the expertise of Karlsruhe Institute of Technology (KIT), where several institutes conduct fundamental and applied climate research, and on the expertise of several associated institutions. The regional focus lies on South Germany. Major topics covered are regional climate modeling, trends of extreme weather events, such as strong rain, and hail, and aspects of energy generation and water management. The South-German Climate Office is one of four regional climate offices of the Helmholtz Association that have a regional and thematic focus each. Since 2009, the South-German Climate Office has been part of the KIT Climate and Environment Center.
