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.

Notice how they never say how many NEW species of birds will emerge in the adaptation to the new climate. The Earth is 4 billion years old. Do these leftist windbags think this has never happened before? Earth lost perhaps 90% of ALL species after the great catastrophic asteroid impact. Somehow Earth recovered and produced new, fantastically diverse plant and animal life.
If another bird takes a dump on my car, it’ll be 901 species at risk.
Survival of the fittest. Adapt or die.
"Save the Slack-Jawed Peckerwood!"
If the birds are not smart and adaptable enough to survive a slight warming process, they are not the fit enough in Evolution's "survival of the fittest".
May I suggest a simple experiment:
1. Take any species and place it an enviroment it’s used to. Worms in the ground, fish in water, etc.
2. Set the temperature of that environment to mean temperature that the species lives in.
3. Count how many of that species you have in your controlled environment.
4. Raise the temperature of your controlled environment by one degree.
5. Count how many of the species die.
6. Get back to me if you can find a single solitary creature where an increase of a degree causes massive death.
If such a species existed, it would go extinct every summer.
If the POTUS just said I am too busy to waste my time with this crap, we have an illegal immigration problem here, an invasion. We must protect our citizens and secure our borders.
>> I’m so sick of this. Is there any way to stop these people?
If enough of their habitat (coffeeshops, sierra club meetings, antiwar protests and the like) was destroyed, they might go extinct.
Remember that the phrase “up to” includes the number zero.
The only world destruction caused by man is due to sin and the justified wrath of God. And we have seen nothing yet. But its coming.
More than 1,000 new species are discovered for every one that goes extinct plus we are creating new ones ourselves. The DNA of recently extinct species is often saved. Once the technology is developed many extinct species will be brought back to life. I imagine within 25 years the dodo bird will be brought back. I just hope they never get the idea of bringing back the Neanderthals. We don't need more welfare state voters.
Yes, that’s them! I’ve not seen one before. LOL!
That prediction has come up over and over again for thousands of years. The feeling of foreboding is a common one. The envi-mentalists are the latest iteration of the doomsday cult theme. It's irrational to believe such predictions since they have such a terrible track record.
oh noes! it’s the end of the world as we know it!
Free human beings will be extinct by then if the corporatist fascist G8 succeed in their truly evil plans.
that’s the scientific method. these people don’t care about the scientific method, environmentalism is a religion to them not a science, that is unless it boosts their number. how dare you question their religion you heretic!! /end sarc

Ping me if you find one I've missed.
Lots of Mexican geese around here doing the goosing that Canadian geese will not do. ;)
