    The atmosphere at 500 hPa above the Greenland ice sheet (GIS) is -33 to -45 degrees right now. The atmosphere at 500 hPa above me at Lake Huron is -43 degrees right now. All of the GIS except a small northernmost part is warmer than here right now when it’s adjusted for its altitude (Earth NullSchool) and right now here is 20 degrees warmer than it was a few nights ago. I think Santa might emigrate from the North Pole to here. I think the North Pole is out of fashion now.

    It would be more enlightening to show the graph of this abnormal situation side by side with the same graph depicting the normal situation. Otherwise, people who don’t know what the normal polar vortex looks like will shrug and say it doesn’t make sense that all this cold in the US is caused by global warming.

    Even the name Polar Vortex is misleading, because it is no longer over the pole, so it is therefore not polar.

    “Symptoms of a changing climate are not always obvious or easy to understand, but their causes and future behaviors are increasingly coming into focus. And it’s clear that at times, coping with global warming means arming ourselves with extra scarfs, mittens and long underwear.”

    As I write this from Waterloo Ontario Canada (43°28′N 80°31′W) the temperature outside is -22 C with an expected high of -18 C. Meanwhile the current temperature in Anchorage Alaska (61°13′N 149°54′W) is +1 C with an expected high of +2 C. The reason why I mention this is this: for the last decade, the winter temperature of Anchorage was almost always higher than Waterloo. Why? The jet stream was a vertical line near Anchorage, which then became a horizontal sign wave over the lower 48 states. Technically speaking, Anchorage was always below the jet stream while Waterloo was always above. These wild changes to the northern jet stream have been attributed to artic melting.
