Great video showing that arctic ice area and volume have declined precipitously over the last 30 years. Can't be denied. Implications are enormous.

No Arctic ice will change every thing we know...

Too early to tell IMO. I will say that this - watch the money. One thing I am curious about are the last 2 years levels. Have they increased? The Antarctic has increased by record numbers the last 2 years. I don't think it is a bad thing to live a little "greener" though given the implications. Same argument for God can be argued here. Regardless of whether or not He exists the benefits of living life as though He does and have that not be true vs. the ramifications of living as though He doesn't and finding out he does are HUGE.

Global sea ice area is currently above long term average level: http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg
So if 90% of the earths current warming is going into the oceans, but that warming is being offset by melting sea ice, then what happen in the next couple of decades when there's no more sea ice during the summer months? Wouldn't we expect to see temperatures start to increase more rapidly after that negative feedback was removed? Now consider the additional positive feedback from the open dark ocean absorbing more heat, and the release of methane from the melting tundra.

+snowleopardNW When you melt a gram of ice it takes 80-calories to change to water, once it's water that same 80-calories heats the gram to 80C/144F how it works, then in fall it has to lose all that heat or the water melts the new sea-ice from below all winter is what's happening. The Beaufort not long ago was 40% 4-9 year-old ice, today that whole areas is "rotten ice" ... nothing like traditional old sea-ice, you can drive a ship through it almost at full speed.

what a junk! they should concentrate on our forests.... but thats  industry far stronger than them , so they picked on us , weak ones... i cant belive that i once took greenies for good guys.... lazy asses

How come the deniers are telling me the exact opposite. I.e. the ice sheets are growing not shrinking. Are these scientist photo-shopping satellite images just to get more money?

i wonder during the medieval warm period there were alarmist nut jobs spouting the same crap, telling everyone to cut down to one horsed chariots not two and i wonder if back then they found the answer to climate change by feeding alarmists to the lions, wala no more climate change, ah those were the days. Any chance of bringing that back, it would solve a lot of problems, just feed the alarmists to the lions and no climate change, sounds very good don't it
Yes, the increase from almost no ice in 2012, to below average ice in 2013, was a big increase. So what?
So you're concerned about humans. I thought this was an environmental catastrophe. Humans, like all other life, will adapt WHEN climate change occurs, just as we have in the past during ice ages and warm periods that were much warmer than now.
