The birds are clueing us in to something, and the message is stark: If we humans don’t reduce our carbon footprint and global temperatures continue to rise unabated, two-thirds of North America’s birds may be dead and gone forever in the next 60 to 80 years.
According to climate science studies in a 2019 National Audubon Society climate watch report titled, "Survival by Degrees: 389 Bird Species on the Brink," 389 vulnerable bird species are in danger of extinction by the end of the 21st century. Fortunately, the report also shows that three-quarters of these threatened species can be protected if we stabilize carbon emissions and keep global heating below 34.7 degrees Fahrenheit (1.5 degrees Celsius).
Only the time we're running out of will tell if we can turn this climate crisis around. In the meantime, birds that are already up against the wall are now literally being painted on walls to help spark public concern about their plight.
