As the Arctic's Winter Sea Ice Hits a New Record Low - What Happens Next? (msn.com) 87
The Washington Post reports that after months of polar darkness, the extent of sea ice blanketing the Arctic this winter "fell to the lowest level on record, researchers announced this week... the smallest maximum extent in the 47-year satellite record, according to the National Snow and Ice Data Center.
"Since then, the ice has already begun to melt again." "Sea ice is acting like the old canary in the coal mine," Dartmouth University geophysicist Don Perovich said. "It's saying loud and clear that warming is occurring...."
In the summer, when the sun's radiation shines down on the Arctic for 24 hours a day, the ice acts as a shield, reflecting more than half of the light that hits it back into space.... With so little sea ice in the Arctic this year, more sunlight will be able to reach the open ocean, which absorbs more than 90 percent of the radiation that hits it. This will further warm the region, accelerating ice melt and exposing even more water to the light. This feedback loop helps explain the rapid warming of the Arctic, and it is expected to lead to a complete lack of summer sea ice in the region within decades, [said explained Melinda Webster, a sea ice scientist at the University of Washington]. The consequences would be dire for seals, polar bears and other wildlife, which depend on a stable sea ice platform to birth their young and hunt for food. It would also expose miles of coastline to pounding ocean waves, accelerating the erosion that threatens to tip some communities into the sea.
But the effects will also be felt in places far from the poles, Perovich said. Studies suggest that a complete loss of Arctic sea ice would raise global temperatures as much as adding a trillion tons of carbon dioxide to the atmosphere. Changes in the Arctic could also affect the jet stream, the river of winds that flows through the upper atmosphere, contributing to more extreme weather around the globe.
"What happens in the Arctic doesn't stay in the Arctic," Perovich said.
Earlier this year sea ice also fell 30% below the amount typical in the Antarctic prior to 2010, the researchers report. The total amount of sea ice on earth has now reached an all-time low, declining by more than a million square miles (2.5 million square kilometers) below the pre-2010 average.
"Altogether, Earth is missing an area of sea ice large enough to cover the entire continental United States east of the Mississippi."

I believe reducing emissions will happen. What it will take is showing people what that means and letting it sink it.
Look at a list of nations by CO2 emissions per capita, such as this one: https://en.wikipedia.org/wiki/... [wikipedia.org]
Sort the list from lowest to highest on CO2 emissions per capita and then scroll down until you see a nation you would not mind moving to. By that I mean the nation has a high standard of living, isn't in some kind of shooting war, fairly democratic government, provides a relatively high access to most any product or service you desire, or whatever else you'd think of as a place you'd live than just visit for the sights and food.
The first that jumps out to me is Sweden. I don't know much about Sweden, I just expect it is a nice place though perhaps a bit "crisp" or "chilly" given its location. Where does Sweden get their energy? Quite a bit comes from biomass and hydro, with a fair bit from nuclear. That works for nations with the right climate and geography but not a plan any nation can follow. The next nation that pops out to me is France. It appears to be a nice place though I've heard of some issues from immigrants. Where does France get their energy? They get a large bit from nuclear fission, and nuclear fission is a low CO2 producing energy source that any nation can implement.
Keep going down the list of nations with low CO2 per capita and see where the "nice" nations get their energy and you should see a pattern. They get energy from hydro and nuclear fission with a few nations also doing well with wind, geothermal, and/or biomass.
I expect to see reducing emissions as people wise up on what gives them the best life as fossil fuel prices rise from wars, scarcity, and other restrictions on supplies. Are there rivers worth a dam for more hydroelectric power? Are there winds sweeping over open plains? Are there hot spots near the surface for geothermal? Is there an abundance of fertile land, water, sun, and labor for cheap biomass fuels? If not then I guess people will have to turn to nuclear fission or see their quality of life diminish as the supplies of fossil fuels diminish.
I expect CO2 emissions to fall. I don't expect CO2 emissions to fall because of some international effort to reduce CO2 emissions. I expect CO2 emissions to fall because as prices rise on fossil fuels more nations will turn to nuclear fission to keep their energy costs low. Efforts in energy efficiency will absolutely play a part but we can't use energy efficiency efforts to get energy consumption to zero. The safest, most reliable, and lowest cost energy for the future will be nuclear fission. The exceptions to that will be regions blessed with ample supplies of wind, hydro, geothermal, and biomass.
Those that believe solar PV and batteries will reduce CO2 and energy costs drank the kool-aid. Can anyone show me a nation that lowered CO2 emissions and their energy costs by increasing reliance on PV + batteries?
Maybe, perhaps, possibly, some nation got to lower CO2 emissions without rising energy costs with a combination of solar PV and some storage method other than batteries, such as pumped hydro. That's a method only available to nations with a climate and geography favorable to pumping water uphill, not something that can be applied generally. The general solution will call for some amount of nuclear fission in the energy mix, just how much a region would need to rely on nuclear fission depends on access to energy from wind, hydro, biomass, and geothermal.
