Hundreds of North American Birds Face Extinction Due to Climate Change, New Study Shows
“Birds are important indicator species, because if an ecosystem is broken for birds, it is or soon will be for people too," senior climate scientist Brooke Bateman warns
North America’s skies could look very different if climate change continues to go unchecked.
According to a new study from the National Audubon Society, a nonprofit environmental group dedicated to wildlife conservation, nearly two-thirds of the North American bird population is facing extinction if global warming hits 3 degrees Celsius (5.4 degrees Fahrenheit).
“It’s a bird emergency” David Yarnold, President & CEO of Audubon says of the findings in their interactive study, titled “Survival by Degrees: 389 Bird Species on the Brink.” “A lot of people paid attention to last month’s report that North America has lost nearly a third of its birds. This new data pivots forward and imagines an even more frightening future.”
The National Audubon Society’s research follows the aforementioned study that revealed the Unites States and Canada have already lost 2.9 million birds in the last 50 years. The nonprofit’s new study shows falcons, warblers, sparrows and owls native to North America are just a few of the birds among the 389 types of birds that have become vulnerable to extinction due to climate change.
Audubon scientists collected their findings by studying migration patterns of birds in comparison to the latest climate models. Through 140 million observations, recorded by birder watchers and scientists, they determined where certain bird species lived. They then used this information, with the climate model, to project where each species may be forced to migrate to — as a result of climate change warming their current environment into unlivable conditions.
This need to find a new home warrants them in danger of extinction as it exposes them to new predators and new conditions they may not be suited for. And while birds become more and more vulnerable, they indicate a looming effect of climate change on humans as well.
“Birds are important indicator species, because if an ecosystem is broken for birds, it is or soon will be for people too,” senior climate scientist at Audubon, Brooke Bateman, warns in a statement to PEOPLE. “When I was a child, my grandmother introduced me to the Common Loons that lived on the lake at my grandparent’s home in northern Wisconsin. Those loons are what drive my work today and I can’t imagine them leaving the U.S. entirely in summer but that’s what we’re facing if trends continue.”

However, there is hope. The study shows that if actions are taken to stabilize carbon emissions and hold global warming to the Paris Accord standard of 1.5 degrees Celsius (2.7 degrees Fahrenheit), then 76 percent of the vulnerable bird species will survive.
“We already know what we need to do to reduce global warming, and we already have a lot of the tools we need to take those steps,” Renee Stone, vice president of climate at Audubon, tells PEOPLE.
“Now, what we need are more people committed to making sure those solutions are put into practice,” she adds. “Our elected officials at every level of government must hear from their constituents that this is a priority.”
