BALI, Indonesia - More than 3,000 flying foxes dropped dead, falling from trees in Australia. Giant squid migrated north to commercial fishing grounds off California, gobbling anchovy and hake. Butterflies have gone extinct in the Alps.
While humans debate at U.N. climate change talks in Bali, global warming is already wreaking havoc with nature. Most plants and animals are affected, and the change is occurring too quickly for them to evolve.
"A hell of a lot of species are in big trouble," said Stephen E. Williams, the director of the Centre for Tropical Biodiversity & Climate Change at James Cook University in Australia.
"I don't think there is any doubt we will see a lot of (extinctions)," he said. "But even before a species goes extinct, there are a lot of impacts. Most of the species here in the wet tropics would be reduced to ... 15 percent of their current habitat."
Globally, 30 percent of the Earth's species could disappear if temperatures rise 4.5 degrees Fahrenheit — and up to 70 percent, if they rise 6.3 degrees Fahrenheit, a U.N. network of scientists reported last month.
It wouldn't be the first time. There have been five major extinctions in the last 520 million years, and four of them have been linked to warmer tropical seas, according to a study published last month in the Proceedings of the Royal Society B, a British scientific journal.
The hardest hit will include plants and animals in colder climates or at higher elevations and those with limited ranges or little tolerance for temperature change, said Wendy Foden, a conservation biologist with the World Conservation Union, which catalogs threatened species.
Butterflies that lived at high altitudes in North America and southern France have vanished, and polar bears and penguins are watching their habitat melt away.
The carbon dioxide emissions that are a leading cause of global warming also turn oceans more acidic, killing coral reefs and the microscopic plankton that blue whales and other marine mammals depend on for food.
"In the long run, every species will be affected," Foden said.
A few will benefit, chiefly those that breed quickly, already exist in varied climates and are able to adapt swiftly to changing conditions, scientists said. Think cockroaches, pigeons and weeds.
The spread of a deadly fungus that thrives in warmer conditions has decimated some frog populations in South America, Africa and Europe.
Then there are Australia's flying foxes.
More than 3,500 gray-headed and black flying foxes — huge bats — died in 2002 after temperatures rose above 107 degrees Fahrenheit in New South Wales, according to a report published last week in the Royal Society B journal.
The rising temperatures are related to global warming, said the author, Justin Welbergen of the University of Cambridge.
"It got really hot and suddenly started raining foxes from the trees," said Welbergen, who witnessed the die-off. "It was quite gruesome. This colony had between 20,000 and 30,000 animals and about 10 percent of those individuals died."
In Australia's Queensland state, temperatures are projected to rise 5.4 degrees Fahrenheit, an outcome that could drive half the species to extinction in a mountainous stretch of tropical rain forest, Williams said.
Even a 1.8 degrees Fahrenheit increase would reduce by half the habitat of the Thornton Peak nursery frog, golden bowerbird and the spotted-tail quoll, a cat-like mammal.
"There are many species and plants that are restricted to the higher altitude areas," he said. "It doesn't take much of an increase in temperature to push them off the mountain. They can't go anywhere."
As temperatures rise, animals are seeking cooler climes. In a study of more than 1,500 species, University of Texas biologist Camille Parmesan concluded that 40 percent had shifted their ranges, mostly toward the poles.
A dozen bird species have moved about 12 miles north in Britain, and 39 species of butterflies have shifted north by as much as 125 miles in Europe and North America, according to another study that Parmesan took part in.
Millions of Mediterranean jellyfish have turned up off Northern Ireland and Scotland. The Humboldt squid, which can grow up to 7 feet long, has moved up the California coast as ocean waters warmed.
"It's the latest in a long series of bad news for fishermen," said Stanford University's Lou Zeidberg, adding that squid have been found as far north as Alaska in the past five years.
With warmer weather, 60 percent of plant and animal species are migrating, breeding and blooming earlier in the spring, Parmesan said. But not all are, and that could upset relationships between birds and the insects they feed on as well as insects and the flowers they pollinate.
"Frogs, birds and butterflies are responding more strongly to warming winters and springs than are plants," she said. "The concern is that this will cause population declines for both plants and animals."
With many species unable to evolve fast enough to adapt, conservationists are considering the creation of natural corridors to encourage animals to move and even relocating them to cooler places. The latter is controversial.
"You are effectively playing God. You are effectively changing evolution on purpose," Foden said. "If our job as biologist is to conserve species, then certainly we must move them. But if it's to conserve natural evolutionary processes ... then we have to give them corridors and let them do their thing."

When I was in high school (in the ‘70s) we had a string of 45 days where the temperature was above 91 degrees, in Missouri.
Wasn’t that when “global cooling” was the big issue?
So why is she wearing a jacket?
An as yet unproven theory now presented as fact. The Big Lie technique.
And in another story - Record Snow falls along the northern US.
This has been going on a lot longer than globull warming. Nature acts as nature wills...
amazing huh?
meanwhile, in North Dakota.. record snow,, not since 1926
Snow sets more records in Grand Forks, Fargo
KXMA-TV Dickinson - Dec 05

More snowfall records in eastern North Dakota. The National Weather Service says the Grand Forks airport had 8.1 inches of snow yesterday, setting a record for the date. And Fargo set a record with 5.9 inches.
After Record, Fargo Area Bracing for More Snow

After a record 7.4 inches of snow Saturday, the Fargo area could see more than 6 inches over the next couple of days. The National Weather Service has issued a winter storm watch through Tuesday afternoon for eastern North Dakota and northwest and west-central Minnesota.
Climate cycles happen periodically.
That’s why they’re cyclic.
Over the course of time, the earth heats up. Then, after it’s hot for a while the earth cools off. warmer cooler, warmer, cooler. and WE as humans don’t affect this cycle at all.
Period.
Things live for a time and then die.
It’s all part of the cycle.
Yes.
BTW, look up what the temperature is doing in Antarctica. Down there is is getting colder year after year.
The world doesn’t have a perfectly stable environment. Who knew?

Another climate scientist heard from. TAKE HEED, EVERYONE!
Oh, wait. He's a biologist. Still, he has the correct opinion, so... TAKE HEED, EVERYONE!
I thought die-offs and extinction were part of the natural process. The die-off culled the bats that couldn’t hack it. Their gene pool with be strengthened by the bats that could. No problem here. All is as it should be.
Ahh...global warming is nature...
Why hasn't the die-off been repeated? Sounds like an anomaly rather than a trend.
And if the earth's temperature rises to 212 degrees Fahrenheit, water will boil at sea level. And if it raises to 450 degrees, tin will melt. And if it raises to 4892 degrees, Osmium (whatever that is) will melt.
And if it raises much more than that, maybe Al Gore will melt and we won't have to put up with him anymore.

Get with the program.....record snows are BECAUSE of global warming.....as are record low seasonal snowfalls.....as are warm winters....as are cold winters.....as are....(fill in the blank with ANY climate-ralated statistic)
Freakin’ d’uh....didn’t you get the memo?
And hundreds of 747s going to Bali helped how?
“More than 3,000 flying foxes dropped dead, falling from trees in Australia.”
Luckily the opossums in Georgia are more hardy and able to stand high tempature changes. What would we do if 3000 opossums dropped dead here? Wait for the other 5 million to follow?
Your point?
"In 1791 near Parramatta, Tench wrote: "An immense flight of bats driven before the wind, covered all the trees around the settlement, whence they every moment dropped dead or in a dying state, unable longer to endure the burning state of the atmosphere. Nor did the perroquettes [parakeets], though tropical birds, bear it better. The ground was strewed with them in the same condition as the bats."
We know that Tench was not exaggerating because earlier this year during the January heatwaves, a similar spectacle befell the bats of Sydney - in spite of the efforts of a team of wildlife rescuers, 3000 flying foxes died from heat exhaustion in a colony at Cabramatta."

Here’s a stupid climate question from a non-scientist (me): If the global temperature increases by about 2 degrees F, why would it affect anything in any significant way? If the average temp in Seattle rises from - say - 57F to 59F, why would that cause any species to die or fundamentally alter our way of life? It might hurt the skiing industry a bit, but help the golf industry. It would make us use a little less energy in the winter and perhaps a little more in the summer, a trade-off. And in the mountains, why would the glaciers melt? In the fall and winter, it would still be freezing most of the time. And in the Arctic, it would be perhaps -8 instead of -10. So why would the icecaps disappear?
You got it; if we have heavy rains, it’s because of global warming. If we have drought, it’s because of global warming. That’s how my dear mom thinks now, because she watches the CBS Evening News and isn’t a FReeper.
“There have been five major extinctions in the last 520 million years”
I didn’t know SUV’s have been around that long.
....the big push is on before the truth gets out, the greenies are going crosseyed over the...the...*gulp* TRUTH!
“Global Warming broke up the Beatles!!!”
Elvis sightings are down too.
How useless and fragile a creature must these bats be if they can't take a 1 degree rise in temps over a century? It's absurd to blame this on global warming for Gods sake. These bats are living outdoors with wide ranges in temps between sun/shade/day night etc. It's not like they are sitting at a desk in an air conditioned office all day.
~~ AGW™ ping~~
.."it went through the net"
.."no it didn't"
.."it did"
.."nope"
.."did"
.."nope"
Keep asking this question. I've yet to hear how 1-2 degrees makes all of the ice caps melt. In fact short the earth being in Venus' orbit I doubt the polar caps COULD completely melt.
At least it won't be women, children, and minorities, for a change.
....the big push is on before the truth gets out, the greenies are going crosseyed over the...the...*gulp* TRUTH!

The rhetoric has definitely been ratcheted up of late,, it’s all over the media,, lots of money to be made off of regulating hot air&gases while it’s “legit”,,
A complete list of things caused by global warming.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
You ain’t said nothin’ ‘bout Mama or trains or trucks or prison or gittin’ drunk so that there ain’t no complete list.
“This colony had between 20,000 and 30,000 animals and about 10 percent of those individuals died.”
According to my detailed calculations, 90% survived, but maybe I need my calculations checked?
Could be.
Possibly.
Perhaps.
I suppose this statement went over the author's own head.
Perhaps their beloved "global warming" is mother nature's way of ensuring survival of the fittest. Looks like it's working to me.
LOL!
I can just imagine these goofs putting this report together,
"But if temperatures rise 3.1715 degrees, 110% of earth's species could disappear."
In the meantime, the sun is strangly missing it’s sun spots, which make the earth warmer. Ice-age anyone?
Absence of sunspots makes the earth cooler.
Think Maunder Minimum or the little ice age.
Point of Order..... global warming is nature.... Darwinian nature.
Bad sentence structure on my part. Sun spots make the earth warmer. Absense makes the earth cooler. Some here are right. If the globe gets cooler, the libs will take credit for it. Humble though they are /s
Sorry. I misunderstood.
There won’t be enough climate change over the next 1000 years for the left to make anything of.
They’re too busy committing genocide on themselves. There won’t be enough of them left by the time the climate changes for them to matter.
