Massive loss of Arctic ice means global warming is now past the point of no return, say scientists

Quote:

...Scientists fear that the Arctic has now entered an irreversible phase of warming which will accelerate the loss of the polar sea ice that has helped to keep the climate stable for thousands of years... This year's record melt means that more of the long-term ice formed over many winters - so called multi-year ice - has disappeared than at any time in recorded history.
... As more sea ice is lost during the summer, greater expanses of open ocean are exposed to the sun which increases the rate at which heat is absorbed in the Arctic region

And here we have a classic dscription "positive feedback" (the result of an input increases the input).

Everything's just fine. Not to worry.

Please don't think they give a shit.

So should we encourage India and Pakistan to have a little atomic war, bringing on "nuclear winter" to cool things down?

That's dang depressing...

If I recall correctly, there was an article about a month ago that basically stated that the 'inertia' of warming meant that it would continue to warm for the next hundred years even if all global emissions of greenhouse gases were completely eliminated.

Did anyone happen to see the special on Nova called "What's Up with the Weather"? It was very well done. The punchline was that there are no viable energy sources right now. Not coal, natural gas, uranium, fuel cells, wind, solar, nothing....

Did anyone read the article in Scientific American about what Global Warming entailed? It dovetailed nicely with this: http://www.cnn.com/2005/TECH/science/09/16/more.big.hurricanes.ap/inde

We're so screwed. Like a really good show on Fox.

So essentially its too late. So why worry?

I'm going outside to cut down a tree, who's with me?

I recall saying exactly this to Hero not too long back, nice that scientists are agreeing with me- sad that I seem to be right.

Everybody get your parkas ready....

Hello, this is my first post. Yea, and on the eighth day Joss made Firefly.

Anyhoo, I hereby state that the evidence available for global warming is inconclusive, and very inconclusive at that. The reason has to do with statistics, but all that needs be known is that the melting and "warming" that is occuring cannot be tied to any specific cause. In fact, what is occuring is not a significant deviation from hot and cool periods during the earth's history (from what we can tell, which is pretty limited). Thus, we don't know why it is happening, but we do know that either it is natural or it is the result of human activity. This is no argument against the ecological movement--I am very green myself. I mean only to point out that there is absolutely no grounds for worrying. In fact, several years ago I read a paper that argued (poorly) that we should be more worried about global cooling than global warming. So don't give up hope or move to the outer rim just yet.

Reading that article just suddenly reminded me of the movie Day After Tomorrow. Has anyone seen that?

If we r screwed then I recomend that everyone should see that movie and take a few notes. As for me. since I saw that movie, I know what to so, I'm heading towards Mexico. I have family there so I'm all set. Anybody wanna come?

Mother Nature reared its uglly head. What a bitch.

May have been on the losing side. Still not convinced it was the wrong one.

Call me a skeptic, but I'm still not buying this 'Global warming ' bit as being anything more than the Earth's natural cycle. We might not understand it or how it all works, but there's a history of the Earth that predates man. Virtually all of it,actually. The Mesozoic inland sea which covered the interior of the United States...you think they got lots of water in New Orleans after Katrina!

It's my position the global climactic changes are occurring, and that they are part of a natural cycle, just sped up 20% or so by human activity.
If that's the case, we'd better be ready for some changes.
If that's not the case, we'd better be ready for some changes.

I think we have some time Chrisisall

What would it require for you to believe otherwise?...
