Climate change affects the reproductive life cycles of plants, including pollen production, which has consequences for allergic respiratory diseases. We examined climatic trends at eight locations in Bavaria, Southern Germany, with time series least 10 years (up to 30 Munich). Bavaria was characterized by a rise temperature, but not during winter. There is also trend towards more continental cl...
