Melting ice kills polar bears, say boffins

Please EXPLAIN Warming to the Dinos 225 MYA

Could someone please explain the HUMAN cause of Global Warming to the Dino and other Earthly Inhabitants 225 MYA (Triassic Period) when the mean temp of Earth was 8 degrees hotter (we're ONLY .5 higher) and the O2 levels were 20% higher and there were NO Polar Ice Caps??

The Global Warming Religion, all you GW "Boffins" and Al Gore are Full of Bull$hit .... and the Dollar sign is quite appropriate (GE is ONE of hundreds of Corporations that are promoting the GW scare and WILL PROFIT From It)

OK, but what we really care about...

... is what global warming is doing to Manbearpig!!

Scary

Hell knows what the offspring of a polar-grizzly cross is, but I think I'll stay out of it's way.

Anyway Mr Gore outght to get righ up there and help round up a few more seal pups for the poor things. I'm sure that will get him some more support.

Save the seals!

isn't this what enviro-greenie Hollywood hippies wanted? to save the seal pups? Then this is a good thing! Kill those nasty bears, because they're eating the seal pups!

I always hope, someday, leftist agenda and enviro-Nazis will someday understand that nature is a complex system. Save the bunny, and the hawk's young starve. Save the bear, the seals die. Heat the water, something melts, and somewhere else there is new growth.

But you can't explain this to religious fanatics. And that's what AGW and earth-firsters are. they love to pretend intellectual and logical superiority with their anti-Christian kneejerk response, think they're so much smarter with their FSM and their lames @ss "jeebus" mockery. But they follow with blind faith the Gaea lines and ignore as much science that opposes their worship as any "intelligent design" follower ever did.

Hollywood and Al Gore need a wake up call. Humans are not as awesome as we like to think we are. Worshipping Humanity (with the capital H) and giving Mankind deity-level power doesn't necessarily make it true. We *might*, if we tried exclusively and really hard, possibly eliminate most of the life on this planet, including ourselves. But in an eyeblink of geological time, it would be right back to whatever new level. By simply being neglectful, we can make changes, which may make things uncomfortable for us, but life would get along just fine.

And even though most greenies lost their long-term memory to chemical abuse, real science shows the planet changed a lot, back and forth, before humans arrived-before even mammals, and before most of the plants you see today even. Does anyone with a brain honestly expect humans will be the last species to dominate here, before the sun dies out?

dead vulture chosen cuz there's no dead cute baby seal icon. PH may be brain dead but isn't cute, so her icon isn't appropriate here.:P

Global Warming is real, dudes!

@Mark: "Hours later and No Such Comment."

Didn't read Webster Phreaky? Funny thing it came right after AC's comment. ;)

@Webster: Warming/cooling cycles and climate change do happen, global warming is happening; the question is if it is really part of nature or because of increased CO2 levels and modern industrial processes. Aside from that, the sheer quantity of pollution generated by zillions of petrol-based engines running are damaging by themselves. Oh well, then again, this comes from someone who thinks there is no such thing as Latin America (as there are NO former Italian colonies in America) ... oh well...

I think the Global Warming camp might have benefited huge in the US because of that "Day After Tomorrow" movie, but even more when a year later, New Orleans went underwater.

Man-Made

The worry about species dying off is real. Sure, the earth was warmer before than it is in our lifetimes...but it took millennia to get there, allowing a broader sample of flora and fauna to adapt to the change, carrying whole ecosystems through the process. The mass-extinction concern revolves primarily around the idea that man-made change will occur too rapidly for enough of the current species to evolve to the new climate and it's changed environments, and the loss of those species (both plant and animal) will contribute to even greater human AND animal losses as ecosystems collapse around the world.

Having said this, I for one could care less if global warming means I never have to see snow again...and living in Ohio, I would expect winter to become the rainy season (you can already see it happening: what used to be inches of snow each year is becoming more and more rain), while the southern US gets burned (again, already in motion). This will drive more people north, in essence driving up my property values as people flood in to seek refuge in the 'new tropics'.

And for starving to death? There will always be food available, but there will be so much less (until new farmlands are 'discovered') that the prices will be astronomical. I've been pretty resourceful about getting fed in times of dire need before. It was for lack of money then that I faced the prospect of not eating time and again. This is essentially what will happen again, and I will deal with it then as I have in the past.

"Survivorship has dropped in the cubs"

Survivorship??? Presumùably they *mean* survival, but in any case I get this vision of polar bears in Boy Scout outfits getting badges for swimming from floe to floe...

@Risky

Panda?

Triassic Global Warming

The cause of the Triassic global warming was plate tectonics.

If the plates are arranged to give open flows of water across both poles, then we get a "hothouse" earth, like the Triassic/Jurassic/Cretaceous/Pliocene period.

If there is open access to neither pole, as at the moment (Pleistocene/Holocene), then we get an "icehouse" earth, which alternates between ice ages and interglacials. We're currently in an interglacial.

The reason for this is that ocean currents carry warmer water to the poles, which prevents them freezing and so lowers the albedo of the planet, raising the temperature. Land at the pole (Antarctic) or surrounding the pole (Arctic) prevents this happening, the poles freeze and the albedo rises.

Leading the Charge

Look into the ones leading the charge on anti global warming. It's the same people who were hired by the Tobacco Companies to try to put the kibosh on the link between smoking and lung cancer. I think we know the result of that one. By the time people figure this one out, it will be too late to reverse it.

You know, we actually used to have some kind of winter here in Florida. Now I'm lucky if I get to wear long sleeves in November at all. Plus, we're in a drought. So if you want them in Ohio, take them! Please! More fresh water for those of us already here!
