lol Why? Is that where your fridge is?So there is only frost at the Artic! :lol:

Yeah, someone posted that news article last week, and then someone posted data showing that the last 10 years were the warmest in 200 years or something like that.
True enough. But then man hasn't really been messing it up for much longer than 200 years. And on top of that, most deniers keep coming up with comments about really short term fluctuations ( winter cold snaps, cool summers, etc. in places) and consider those as enough to refute the long term trends.AnnaG, Oh ok, didn't know that, just something I came across. 200 years isn't much of a gauge for temp, considering the earth has been around a little longer than that

I think so. It isn't like some 3rd grader or gift boutique owner thought of it and it caught on.

Clever...but the person I was addressing called it frost...not ice.
Not quite. Floating ice, which most of the Arctic ice is, won't increase sea levels by melting (remember Archimedes' Principle?), it's the stuff on land, Greenland and Antarctica in particular, that'll raise sea levels by melting.Oh about the connection between the melting ice and sea levels: it's not the melted ice that adds to the water and increases levels (it does but not significantly) but rather the resulting temperature increase from that process that eventually raises sea levels.
You may be right, I can't remember where the comment came from. But this time I know it was scientists that said this latest prediction and they did say "might be".But it wasn't even close to an educated guess.
I'm not sure what the mainstream media says but " A nearly ice-free Arctic Ocean in the summer may happen three times sooner than scientists have estimated.
It sure would be for bears. I think 3 miles is about max for the length of swim bears can do. And it's pretty tough sitting outside a airhole in the ice waiting for food if there is no ice. I'll have to look up how far they can swim to be sure, though.Think about it! "Ice-free Arctic" is prison-like expression. Real freedom comes by keeping the ice.

Ok I was waaaay short, they've been seen swimming at 100 km from shore.

Thermal expansion?
So many people forget/dump on/abuse the global ocean. Way more heat stored there than the atmosphere.
Ah, that's very interesting, and good science, pays close attention to details. I hadn't seen that before, thanks for the links. A 4 cm rise in sea level is, as you say, not nothing, but in the overall scheme of things it's pretty inconsequential. Tides rise and fall far more than that in most places, so it wouldn't create any problems by itself in that context. The critical point would be the loss of the Arctic ice cover, not the rise in sea level it produces. But still, I think every little bit hurts, so that's useful information.This has been the standard lore, but a Professor at St. Mary's University in Halifax...
