Climate Models Predicted The Opposite Of What Has Caused Record Cold US Weather
Of particular note, the article points out that climate models actually predicted the opposite pattern to occur with the jet stream drawn north, with fewer jet stream dips, and no change in jet stream blocking:
“These [modeling] studies suggest that a warming Arctic will draw the jet stream’s average track north. Blocking patterns will decrease. Moreover, the models indicate no “robust” decrease in the jet stream’s speed, notes Elizabeth Barnes, a climate scientist at Colorado State University in Fort Collins who focuses on the jet stream’s behavior and the factors affecting it. To be sure, the models could be wrong, she acknowledges. But when different teams with different models converge on the same answer, that inspires more confidence in the result.”
[...] Furthermore, the article notes “Long-term swings in Atlantic sea-surface temperatures, known as the [natural] Atlantic multidecadal oscillation, appear to have the same effect on the jet stream’s meanders and blocking patterns that Arctic warming and sea ice are purported to have.
