But why does the vortex weaken? Now it gets interesting. More and more Arctic sea ice is melting during summer months. The more ice that melts, the more the Arctic Ocean warms. The ocean radiates much of that excess heat back to the atmosphere in winter, which disrupts the polar vortex. Data taken over the past decade indicate that when a lot of Arctic sea ice disappears in the summer, the vortex has a tendency to weaken over the subsequent winter, if related atmospheric conditions prevail over the northern Atlantic Ocean. The situation looks something like that shown in the graphic below. (For a full explanation, see the Scientific American article that accompanies the graphic.) Although the extent of summer sea ice in the Arctic varies year to year, overall it has been disappearing to a notable degree since 2007 and it is forecast to continue to vanish even further. That could mean more trouble for the polar vortex, and more frigid outbreaks—a seeming contradiction to “global warming,” perhaps, but not for “global weirding,” also known as climate change. http://blogs.scientificamerican.com...s-this-polar-vortex-that-is-freezing-the-u-s/
Climate activists ‘considering the benefits of greater centralisation in decision-making’ to combat climate change ‘Is democracy hurting our climate change response?’ – China’s centralized power the ideal?! 'A number of climate advocates have begun considering the benefits of greater centralisation in decision-making to mitigate the devastating scenarios offered by climate scientists.'
Sorry I am not inclined to respond directly to any more of these same posts of yours. If you have anything new to add please do so, and I'll be happy to read it. This article by Lindzen sums up my position on global warming. I have made many of the same points as Lindzen has in my various posts, but he has nicely summarized them in this one post. So please read it. http://www.webcitation.org/6JhfqVziU Lindzen, by the way was a lead author for the IPCC, so rest assured that he is knowledgeable.
