Global Warming's Silver Lining For the Arctic Rim

Pickens writes "According to Laurence C. Smith, an Arctic scientist who has consistently sounded alarms about the approach of global warming, within 40 years the Arctic rim may be transformed by climate change into a new economic powerhouse. As the Arctic ice recedes, ecosystems extend, and minerals and fossil fuels are discovered and exploited, the Arctic will become a place of 'great human activity, strategic value and economic importance.' Sparsely populated areas like Canada, Scandinavia, Russia and the northern United States — the northern rim countries, or NORCs — will become formidable economic powers and migration magnets. Predictions in Smith's new book The Earth in 2050 include the following: New shipping lanes will open during the summer in the Arctic, allowing Europe to realize its 500-year-old dream of direct trade between the Atlantic and the Far East, and resulting in new economic development in the north; NORCs will be among the few place on Earth where crop production will likely increase due to climate change; and NORCs will become the envy of the world for their reserves of fresh water, which may be sold and transported to other regions."

They are not the main obstacle anymore, its greenwashing, lack of public information on effective actions, and political stalemates due to business interests, business as usual. For example, huge efforts to sell cars doing 45mpg only, instead of 25mpg, but almost none to encourage anyone to leave the car home, which would be 0gallon per mile, and everyone can try to do it, no fancy new car requirement and limitation.

Hahaha, yes it's been horrible.

The real problem with the Arctic rim isn't heat, although lack of heat is a challenge. The real problem is sunlight. The northern regions of the Arctic rim doesn't get enough sunlight to sustain trees, then there's a belt of pine needle like conifers, then there's a transient belt of broad leaved trees.

Personally, I hope that we never develop the Arctic rim in a meaningful way. The broad leaved trees produce an unbelievable amount of oxygen out of CO2 in the relatively short growing season. We've already decimated the rain forests, the oceanic regions of oxygen production are down a bit due to phosphorus posioning (or some other pollution, they think it's phosphor), and the Arctic region's oxygen contribution becomes more important every day.

"It is also true that 500 mil years ago, Earth was a ball of ice despite the fact that atmospheric CO2 was ~4200ppm (about 12 times higher than today). Oh yeah, you guys always forget to include that 'law of physics.'"

I am certainly not an expert in the subject, but my basic understanding of snowball earth is that first the continents got into a position that led to a runaway glaciation. More ice on the ground/water equals more light reflected equals more ice forming. Once the entire earth was covered in ice there was no photosynthesis going on, so carbon dioxide started to build up, mostly from volcanic activity. In fact according to the citations on wikipedia it didn't build just up to 12 times higher than today, but might have been more than 300 times higher before there was enough greenhouse heating to overcome the cooling effects of reflection from all the ice.

You seem to be implying that high levels of CO2 at the same time the earth was frozen over somehow contradicts global warming when in fact it supports the idea. Were you not aware of that? Or were you just hoping that we weren't? (And in any case, how is a fact or set of conditions a "law of physics"?)
