Chat on Persistent Cold Blob over North America

Chat on Persistent Cold Blob over North America 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.
