Upsetting? Hardly. But what exactly do you think those links prove? Especially in light of the fact I didn't address any of them. What it does prove is that you are breathtakingly uninformed on these issues. First on the list. Antarctic sea ice extent. Do you know what governs sea ice extent, especially in Antarctica? Winds. Winds open polynyas. The surface freezes. For sea ice, the important metric is the thickness. The thicker it is, the more likely it is to survive the summer. In the Arctic, the sea ice has been thinning at a rapid clip. Which really isn't a factor in Antactica because, except right around the continental margin, it melts in the summer. For Antarctica, the important metric is the ice on the continent. Ditto for Greenland. Both have lost an enormous amount of ice and at an accelerating rate. nsidc.org nsidc.org The satellites GRACE and IceSat have helped us to see this. Anything having to do with cold winters in the northern hemisphere. Ok, this is going to be tough for you. The higher latitudes have been warming at a faster clip than the lower latitudes. To ease the strain on your brain, that means that the temperature differential has decreased. That temperature differential is what drives the jet stream. The jet stream helps keep arctic air in the arctic. The decrease in temperature differential means that the jet stream has gotten erratic. In some places it trends much higher in latitude than it normally does. This has resulted in warm winters in places like Alaska. They had to move the start point of the Iditarod this year because of lack of snow. In other places it trends much lower in latitude, like the East Coast of the US. This results in polar vortices coming down for visits, dropping huge amounts of snow. Again, you expose your ignorance. It must suck to be so wrong when you were convinced you were so right...
