Opinion: As a birder, I see the effects of climate change every day. Now, Audubon has quantified the threat (via latimesopinion)
For serious birders who regularly observe birds in the wild, ignoring climate change isn’t possible. We have been seeing and documenting the effects of a warming climate since at least the 1950s.
Similar patterns are playing out across the continent as scores of species redraw their range maps, appearing in new areas farther north and vanishing from sites farther south. And the pace is accelerating. Ironically, the changes will make birding more exciting for a while, with birders finding new species in unexpected places, but the downside will be brutal. If warming continues unchecked, Audubon’s models show, many birds will lose massive amounts of territory.
We still have time to do something about it, however. The potential loss of 389 North American species projected in the Audubon study is what would happen if global readings go up by 3 degrees. But the scientists also modeled what would happen at lesser levels of warming, and the results are striking. Limiting warming to 1.5 degrees would reduce the danger for three-quarters of those threatened birds, Audubon’s modeling found.
