Impact of climate change on populations of European birds, 1980-2005
The index is set to 100 in 1980. The orange line shows the modelled weighted composite trend of 30 bird species. It shows an increase of their geographical range in the study region. The green line shows the modelled trend of 92 species that have lost range. Range changes were modelled by averaging using three global climate models and two emissions scenarios.
