Audubon’s Bird-brained Conclusion: More Global Warming Misdirection

Filed under: Adaptation, Animals

There is an interesting (of course!) new post up over at MasterResource.org taking a closer look at the Audubon Society’s latest pronouncement about birds and climate change. Here it the abstract:

On Tuesday, the National Audubon Society released a report “Birds and Climate Change” which interpreted an average northern shift of the over-wintering range of a large collection of North American bird species over the course of the past 40 years or so. Audubon decided that this range shift was due, in part, to “global warming.” Therefore, it was bad and action must be taken to avert it:

It is the complete picture of widespread movement and the failure of some species to move at all that illustrate the impacts of climate change on birds. They are sending us a powerful signal that we need to 1) take policy action to curb climate change and its impacts, and 2) help wildlife and ecosystems adapt to unavoidable habitat changes, even as we work to curb climate change itself.

What the Audubon Society failed to mention was that contained within the data from its own report was that the numbers of bird species with increasing populations topped those with population declines by a margin of more than 2-to-1. In other words, “global warming” has been a net benefit for the Audubon’s collection of North American bird species. Which leaves you wondering, why would we want to take action that could result in a countering of that trend?
