The last paragraphs:

"Once Blue Ocean Events persist for many months and the Arctic warms up considerably, the jet stream will lose its energy due to a lessening of the temperature difference between the Arctic region and the tropical region. At that point, storms that form in the mid-latitudes will be stuck in place or drift very slowly, having little or no jet stream steering currents to move them along. This will cause them to drop excessive rainfall on areas in which they occur, causing so much rain that crops cannot be sustained. In other places, long-lasting heat waves and droughts will occur since the lack of jet stream steering currents will keep rain-free heat domes in place. This would obviously be devastating for humans that rely upon steady sources of food and water since crops cannot grow during extended heat waves and droughts.

Essentially, a catastrophic reoccurring Blue Ocean Event in the Arctic Ocean would end life as we know it. Human civilization has been built on the ability to grow crops reliably and get them to people who live away from farms for sustenance and survival. Civilization has also been built on reliable access to drinking water. If both are no longer available, due to the jet stream’s weakening and accelerated global warming, humans will have to rapidly adapt to survive.

Many will likely die in this scenario, as large portions of crop-growing regions transition to semi-arid or fully arid (desert) climates. Starvation and a lack of access to drinking water will impact billions of humans, causing mass die-offs. Those that remain will have to quickly find ways to produce food and obtain drinking water in the warmer Blue Ocean Event climate."
