Two-thirds of North American birds, 389 species, are at risk of extinction because of the ecological impact of climate change, according to a report from the National Audubon Society. It maps how the warming climate shrinks the range where birds can live because of extreme weather, sea and lake level changes, and changing urban and agricultural land use. The MacArthur-supported report recommends actions to adapt to the changing climate in addition to strategies to mitigate climate change that would reduce vulnerability for 76 percent of birds.
