Our destabilizing climate has many unpleasant surprises over our entire planet. The Arctic is warmer than normal by 5.7C; Antarctica is 2.4C colder than normal. A long-term, stuck Rossby wave trough of the jet stream gave North America a cold blob; basically a “global warming hole”while the rest of the planet baked. As the Arctic “center of cold” shifts from the North Pole to central Greenland (83 degrees N latitude) this cold blob could become a frequent feature as we near a Blue Ocean Event in the Arctic.
