As G8 countries try to hatch a plan to tackle rising CO2 emissions (see "Climate wrangles"), a global analysis of the effects that human activities will have on land birds is ruffling conservationists' feathers.
By 2050, up to 900 species of land birds could be threatened by climate change and habitat destruction through activities such as logging. By 2100, the number of bird species on the World Conservation Union's Red List of threatened species may more than double.
Walter Jetz from the University of California, San Diego, and colleagues mapped the distributions of all 8750 known land bird species against habitat changes predicted in several potential environmental futures in the UN's Millennium Ecosystem Assessment (PLoS Biology, vol 5, p e157). "Species in temperate regions will suffer mostly from climate change," says Jetz, "but in the tropics, where birds are especially diverse and have small ranges, land conversion such as deforestation will have an even bigger impact."
"The specialists confined to small areas don't cope well with habitat change, and this applies to many tropical bird species," agrees Bill Sutherland, a conservation biologist from the University of Cambridge.
By identifying fragile regions, Jetz hopes his work will help policy-makers become more proactive, with improved targeting of conservation efforts. "Protecting tropical forests is also a strong buffer against future climate change," he says.

It’s interesting how they keep these classroom topics from the Sophomore year in the headlines.
Pure BS from the IPCC of course:
” The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change, associated disturbances...20-30% of plant and animal species assessed so far are likely to be at increased risk of extinction “
Known species extinctions in the last several centuries total about 1,000, with very few if any solely attributed to man-made climate change.

PS: These fear-mongers are now lumping in deforestation, farming,etc with man-made CO2 since man-made CO2 is preactically irrelevant they now desperately go over the top with- EVERYTHING MAN DOES WILL DESTROY THE PLANET.
Makes me sick.
Good! The damned songbirds start up just before the sun rises here (Roswell, GA). I never get to sleep in because of all their singing.
It is here to stay. FOREVER. It might end after political correctness ends. Chances of that? Nil. People are making too much money scaring ppl.
Bad news...songbirds are projected to thrive in North America. If only Canadian geese were required to get visas...
So all these let's 'save the slack-jawed woodpecker' and 'Have you fed a purple people-eater today?' endangered species programs are just so much hype.
(I really don't know that for sure, but neither do the free-loading hypesters know that it isn't true. But then, I'm not getting paid for my guesswork.)
Start by putting bu||sh|t sites like this one in your hosts file like I did yesterday, is all that comes to mind.
It is scary to see that "NewScientist " appears to mean, "Correct Scientist", or "Pimped Scientist".
We are all doooomed! Just like the ice age I went through they told me about happening.
I need to get eating then, so I can try one of each before it’s too late.
“Is there any way to stop these people?”
Other than declare hunting season or force them to sterilize so they don’t breed again, I do not know.
Birds Ya’ Say ??,,,mmmmm,,,I recommend a 20 gauge,#6 shot,,
That won’t tear em’ up too bad...;0)
Memo: It’s now, of the people, by the people, and for the birds and those who trade in guano.
I saw a pile of dove feathers this morning. Probably a from a hawk of some kind that was enraged by the excess of CO2.
