Human-caused climate change via fossil fuel burning produces a number of stranger things. And some of the weirdest happen to occur in the polar regions of our world.
One of the foremost of these odd impacts is called polar amplification. Under polar amplification, the warming effects of elevated greenhouse gasses are concentrated at the poles. This is due to reduced reflectivity (albedo) from smaller snow and sea ice concentrations, due to the increased intensity of the greenhouse effect in colder and darker regions, and due to increased energy transfer from lower latitudes into upper latitudes due to weakening of the polar Jet Stream.
Over the next week, this kind of polar amplification is predicted to generate very extreme warm temperatures for both poles of our world.
