Arctic melting faster than expected

Guess I'll have to go look at what Gavin and the boys at RealClimate.org are saying. LOL

Then go look at what crap Ol' Steve Miloy is posting on his site. :lol:

Good, maybe we'll run out of oil sooner than later too.

 

Quick! Someone should go up to the polar ice cap and it global warming is a hoax!

 

Its all the Hot Air being blown about by the "Global Warming" crowd! :lol:

I think you only have to be careful when you state particulates or aerosols and their attributed cooling or warming effects. Things like soot can do both.

Seems to me that the aerosols would last longer in the atmosphere since they are chemicals and others particulates are organic or somewhat organic in nature. Thus aerosols probably/only break down over a period of time, a long period of time. I know that some bacteria can break down chemicals but its kind of hard to get them into the atmosphere where they can do the work necessary. Just my 2 cents.

I find it funny that no one here is really questioning what the article is saying. I, for one, would like to know how they know there will be a "sudden speed up" of the melting process - it doesn't seem to make sense, although there could be a perfectly good reason for it.

but more importantly... if the North Pole is gonna all melt away and sink into the ocean, what will we tell all the children of the world? That Santa decided to move his workshop to the Caribbean to work on his tan?

The summary source of the article is at http://www.ucar.edu/news/releases/2006/arctic.shtml. The scientific article is being published today in Geophysical Research Letters.

The reason for the sudden speed up they give is:
"The research team points to several reasons for the abrupt loss of ice in a gradually warming world. Open water absorbs more sunlight than does ice, meaning that the growing regions of ice-free water will accelerate the warming trend. In addition, global climate change is expected to influence ocean circulations and drive warmer ocean currents into the Arctic.
"As the ice retreats, the ocean transports more heat to the Arctic and the open water absorbs more sunlight, further accelerating the rate of warming and leading to the loss of more ice," Holland explains. "This is a positive feedback loop with dramatic implications for the entire Arctic region."

And I think it's obvious that if the north pole melts away, Santa will go live with Sponge Bob.

 

And of course, lets not forget the "Hollywood effect" from global warming - we have to be bashed with movies about "super storms" and such, over and over and over again...

What's sad is there is often some truth to those movies. If you are annoyed by them and not concerned then there is a problem. There are plenty real-life storm related disasters that have happened recelnty that might not been nearly as catestrophic has humans used their heads. Climate shifts can happen rather abruptly and with our current infrastructure and "information deficient" population we could be affected in a most dramatic way. I really wish Sacramento would see some sort of crisis where electricity shuts down and gas stops flowing. If even for only a week. Maybe people would then see how fragile our system really is.

Yes, i'm annoyed by them. for the most part they're poorly written, poorly acted, and poorly directed. the only redeeming value they have is the special effects, which frankly are starting to get a little old. I watch movies for entertainment, not knowledge - if i want to learn more about the possible consequences of global warming, then there are many other avenues for that.
