"If the climate is not warming, why is the Arctic sea-ice melting?"

It's not; by historical levels the Arctic melt is small; for some calculations of the melt, see:

There is nothing unusual happening in the Arctic yet the usual idiots, like vultures, will jump on anything to 'prove' their religion of AGW.

IT'S GLOBAL WARMING STUPID

>>Yes, yes, it’s unsophisticated to blame any given storm on climate change. Men and women in white lab coats tell us—and they’re right—that many factors contribute to each severe weather episode. Climate deniers exploit scientific complexity to avoid any discussion at all.

Clarity, however, is not beyond reach. Hurricane Sandy demands it: At least 40 U.S. deaths. Economic losses expected to climb as high as $50 billion. Eight million homes without power. Hundreds of thousands of people evacuated. More than 15,000 flights grounded. Factories, stores, and hospitals shut. Lower Manhattan dark, silent, and underwater.

[...]

In an Oct. 30 blog post, Mark Fischetti of Scientific American took a spin through Ph.D.-land and found more and more credentialed experts willing to shrug off the climate caveats. The broadening consensus: “Climate change amps up other basic factors that contribute to big storms. For example, the oceans have warmed, providing more energy for storms. And the Earth’s atmosphere has warmed, so it retains more moisture, which is drawn into storms and is then dumped on us.” Even those of us who are science-phobic can get the gist of that.>>

Poirot:
"We are voracious - and we have no idea how to contain our appetites".

Worse than that, our economic prosperity (such as it is) demands the glut is not merely maintained, but increased:

Mr Creasote seems much less far fetched these days.
The only way to address AGW is to deny ourselves (and cripple the economy), all else is magic pudding. Either consumerism dies or we do, and there's nothing democratic capitalism can do about that.

So the Arctic sea-ice is not melting. That's good to know.
All those photos must be from Photoshop.
Glad to get that cleared up. Such a relief!

This climate change debate drives me nuts, it's like the new religion, it's based on faith not science.

So the ice caps are melting? so it must be mans activities? correlation is not causation! have you considered the possibility of increased polar winds leading to a high melt rate?

Any one that argues against the fact of climate change is an idiot. The climate has always changed, the global climate is a hugely complex dynamic entity. The argument is so badly played out in the media, the issue is anthropogenic climate change. To what extent are the activities of man contributing, if a all, to the observed climate change. I see this as part human psychology, we can't accept that we are not masters of the universe, we can't accept that we humans are puppets on a string when it comes to mother nature. If the sun doesn't come up tomorrow we are dead and there is nothing we can do about it.

"All those photos must be from Photoshop.

It wouldn't surprise me in the least; AGW is a scam from top to bottom and its advocates have been lying from day one.

Anyway why don't you go up to the Arctic and check yourself; this mob of fools had a go:
