A new report from the National Audubon Society shows that two-thirds of North America’s birds face major challenges including extinction if global temperatures are allowed to increase 3 degrees Celsius by 2100. However, if temperature rise is limited to 1.5 degrees, the majority of those disruptions can be stopped. 

While many scientists believe that a 1.5 degrees C rise in temperatures above pre-industrial levels is already inevitable, and some claim that the 2-degree threshold has already been crossed, the Audubon report suggests that there’s still time to mitigate some of the damage to birds. Limiting temperature rise to just 1.5, the report says, would limit the extinction vulnerability of 70 percent of North American species at risk.
