What will happen before the year 2100

Hundreds of species of birds will be extinct by 2100

Everyone loves birds, except maybe poor Tippi Hedren from The Birds. They’re cute and colorful and ensure that our nation’s cats will never go hungry. But at the rate we’re going, we’re going to see many fewer feathered friends by century’s end.

According to a 2011 study on climate change, upcoming extreme weather, both hot and cold, will likely start killing birds off en masse. The study believes that, if global temperatures rise 3.5 degrees Celsius (38 degrees Fahrenheit), anywhere from 600 to 900 species of birds will go extinct. What’s more, the study states that for every extra degree in temperature, 100 to 500 more bird species will die off. Most affected would be birds living in places where the temperature rarely shifts all that much. If those places suddenly get too hot or too cold, the birds likely won’t be able to adapt and survive.

While that number is low compared to all the birds in the world — according to the American Museum of Natural History, there are currently about 18,000 species of ex-dinosaurs roaming the land and skies — it’s still an alarming extinction rate. It would get worse if some places on Earth jump over 16 degrees Celsius, as the UN fears. If that happens, we could lose half our birds in under 100 years. A future like that is, dare we say, for the birds.
