Climate change is casting its ill effects on the fauna of North America. The existence of nearly half of the birds studied in North America has been threatened due to climate change. This has been the conclusion of a seven year long study.
The study was sponsored by U. S. Fish & Wildlife Service and issued by the National Audubon Society and involves the study of 588 bird species. The study revealed that nearly 126 species of birds are in the brink of extinction by year 2050.Further 314 species are threatened with extinction by the year 2080, if emissions of greenhouse gases continue at the current levels.
The scientists examined surveys of North American Breeding Birds which was compiled by the US Geological Survey for four decades along with the climate data of North America.
The links between where birds live and the changes in climatic conditions like temperature and rainfall are being studied in the Audubon Christmas Bird Count. The results of the study are worrying and calls for aggressive steps to reduce greenhouse gas emissions.
Audubon New York’s Executive Director Erin Crotty said, “Now, more than ever, we have a responsibility to be the voice of the birds and aggressively combat the urgent threat of climate change by further reducing greenhouse gas emissions and protecting the places that birds need to thrive and survive.”
The list of species which are threatened by climate changes includes hawk owl, and Baird’s sparrow, the northern gannet, three-toed woodpecker, the trumpeter swan, and the rufous hummingbird.
