It's summertime in the arctic. The Arctic ice sheet has been losing upwards of 100,000 square kilometers per day.

Seven square miles is approximately eighteen square kilometers.

At it's lowest, there will be approximately 6,000,000 square kilometers of sea ice left in the arctic. At the end of september, the sea ice will once againbegin it's increase to about 14,000,000 or 15,000,000 square kilometers until next years melt off.

Etc.

It's newsworthy but certainly not unprecedented.

Thanks for the data once again MikeB.
Scientific facts are always lacking in the media spin. Come to think of it scientific process is the only way through the quagmire of political nonesense and mindless panic.

The facts??? The article says: "consistent with the theory that the current Arctic climate isn't rebuilding ice sheets." NOT REBUILDING. As in: in a very few years, there will be no more ice in the Arctic in summer months.

Maybe not "mindless panic", but great trepidation and anxiety -- those would be appropriate.

"Mindless panic" is matched by its equally pathetic "There isn't any problem, because my political party says there isn't". Or how about "There isn't any problem, as long as it doesn't affect my vacation plans". At least one side acknowledges and debates the issues. The other has their heads ... in the sand.

This NOT about the seasonal decrease in the FLOATING ice SHEET, BUT rather the breaking loose of an ice SHELF.

The two are quite different.

"Researcher Derek Mueller was careful Tuesday not to blame global warming"

Ice shelves break away because of additional ice buildup, like glaciers do. This has been expected since 2002.

Let me get this straight, the researcher did NOT blame global warming, however, you guys know better.

There is an almost universal blind spot: rising prices globally are not a blip, but are from underlying resource depletion and pollution. Global warming is just ONE aspect of pollution. There are many many others, including dioxins likewise found last decade in Arctic mothers' milk.

Why can't intelligent people make the connection with all these warning signs that there are just too many humans consuming and producing?

Because too many think they are children of god and therefore exempt from nature's laws. Keep doin what your doin people ... when your prayers for a devine intervention never materialize, you will feel earth's pain, then possibly realize that we are nothing special.

I think you raise a good point but are generalizing a tad. Not all beliefs contradict with science/nature. True if you look at history science has whittled away at things that used to be explained by religion/divine intervention. I think Einsteins view of god is an interesting one. Specifically that god is not concerned with the everyday nuances of individuals lives.
Science (MRIs) indicates that human brains are evolved chimp brains. It functions by way of feelings stemming from the limbic system and giving rise to desires. These were tuned to pre-historic times. Some of these processes are incompatible with modern life. Intellect can overcome the defficiencies. However 99% of the population are not taught how their mind works. The mind is an elegant machine that requires training to use effectively. Until then we will continue to:
-polute the fragile earth life capsule
-have tribal squables and bullying
-be mindless consumers
One way we might surpass our biological limitations is by the next tech revolution -automation of thought - sentient computers.

Sentient computers? Will that be a new political party?

Talk about going from bad to worse...
