Climate change impacts on BIRD SPECIES

How Climate change threatens bird species

A recent status report compiled for WWF reviews more than 200 scientific articles. It finds a clear and escalating pattern of climate change impacts on bird species around the world, suggesting a trend towards a major bird extinction from global warming.

Specific groups of birds are at high risk from climate change: migratory, mountain, island, wetland, Arctic, Antarctic and seabirds.

While bird species that can move easily to new habitat are expected to continue to do well, bird species that thrive only in a narrow environmental range are expected to decline, and to be outnumbered by invasive species.

Birds suffer from climate change effects in every part of the globe. Scientists have found declines of up to 90 per cent in some bird populations, as well as total and unprecedented reproductive failure in others.

Scientists also analyzed available projections of future impacts, including bird species extinction. They found that bird extinction rates could be as high as 38 per cent in Europe, and 72 per cent in northeastern Australia, if global warming exceeds 2 º C above pre-industrial levels (currently it is 0.8ºC above).
