In a new study published Thursday by the National Audubon Society, scientists say that saving hundreds of bird species from extinction by the end of this century is entirely possible--but that without commitment from policymakers to end human-caused global warming, two-thirds of North America's birds could be gone by 2100.
The report, "Survival by Degrees: Bird Species on the Brink," found that 389 out of 604 North American bird species are at risk of extinction by 2100 if the Earth's temperature rises by 3 to 5o Celsius, as it's projected to if the current trend of emitting millions of tons of carbon each year continues.
\u201cIt\u2019s a bird emergency: Two-thirds of America\u2019s birds are threatened with extinction from climate change, but keeping global temperatures down will help up to 76 percent of them. #BirdsTellUs https://t.co/evshGW2zd9\u201d— David Yarnold \ud83c\uddfa\ud83c\uddf8 (@David Yarnold \ud83c\uddfa\ud83c\uddf8) 1570716347
The Society released its report less than a month after the Bird Conservancy of the Rockies revealed that nearly a third of North American birds--about three billion--were lost over the last five decades.
Thursday's study predicts "an even more frightening future" unless the climate crisis is stopped, Audubon Society CEO David Yarnold said in a statement.
"Birds are important indicator species, because if an ecosystem is broken for birds, it is or soon will be for people too."
--Brooke Bateman, Audubon SocietyThe group looked at 140 million bird records and measured the effects of sea level rise, urbanization, and extreme heat on bird populations. Many of the changes caused by increased carbon in the atmosphere will drastically reduce the range in which birds are able to live, the study found.
"Birds will be forced to relocate to find favorable homes," reads the report. "And they may not survive."
The Audubon Society created an interactive graphic allowing users to view how warming of 3o Celsius or more would affect various species versus warming of 1.5o, which the Intergovernmental Panel on Climate Change says is the upper limit for global warming in order to avoid the worst effects of the climate crisis.

The bobolink, which lives in the northern U.S. and southern Canada, would lose 88 percent of its current habitat range by 2100 if policymakers don't pass laws to help limit the warming of the globe, and would be forced to move north. The species would lose only 43 percent of its range if the Earth warms 1.5o Celsius.
Other birds at risk for drastic habitat loss include the Baltimore oriole, the saltmarsh sparrow, and the purple finch.
The prediction of an extreme loss of bird species by 2100 also points to danger for humans as well, the Audubon Society said.
"Birds are important indicator species, because if an ecosystem is broken for birds, it is or soon will be for people too," said Brooke Bateman, senior climate scientist for the Society.
But the group stressed that with commitment from government leaders around the world, more than three-quarters of bird species in North America are expected to have far greater outcomes at the end of the century, retaining more of their habitats.
\u201cAudubon's science shows how devastating the climate crisis could be for birds. It also shows that if we act soon, we can help a majority of these species.

"By stabilizing carbon emissions and holding warming to [1.5o Celsius] above pre-industrial levels, 76 percent of vulnerable species will be better off, and nearly 150 species would no longer be vulnerable to extinction from climate change," the report reads.
Renee Stone, the group's vice president for climate, called on the public to make clear to election officials that reducing carbon emissions to net zero in the next decade, and therefore stemming the crisis, is a top priority for them.
"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. Now, what we need are more people committed to making sure those solutions are put into practice," said Stone.
While "there's hope in this report," Yarnold said, "it'll break your heart if you care about birds and what they tell us about the ecosystems we share with them. It's a bird emergency."
