Climate change already forcing world's birds towards poles, says report
The world’s birds have begun flocking towards the earth’s north and south poles and upwards to higher ground as climate change begins to transform their habitats, a new report has found.
One quarter of 570 bird species studied globally have been affected negatively by climate change, while 13% have responded positively, says the study by Birdlife International.
Tris Allinson , one of the paper’s authors, told the Guardian: “People regard climate change as something on the horizon and about to happen but the signals from birds are that significant and profound changes are already occurring, with detrimental effects for a large proportion of the birds studied.”
“We are seeing a consistent pattern of birds moving towards the north and south poles in their respective hemispheres, and moving to higher altitudes on mountain slopes,” he added.
