"A study conducted by a team of Stanford researchers has drawn out a grim scenario of what is likely to befall land-bird species worldwide as average temperatures continue to rise"
"Using data from the latest IPCC summary report and a wide range of likely scenarios, Sekercioglu and his colleagues modeled changes to the elevational limits of the ranges of over 8,400 species; the worst-case scenario of a 6.4°C temperature uptick produced the 30% extinction projection."
"Of greatest concern is the authors' finding that each extra degree of warming will have increasingly disproportionate consequences: For example, if current temperatures were to rise by 1°C, we would likely see 100 extinctions; assuming temperatures were to rise by 5°C, however, an additional 1°C then would trigger a much larger number of extinctions, 300-500."

What do you think of these scientists' grim conclusions?
