Draft script:
You’ve probably heard a lot about the AMOC, which is short for the Atlantic Meridional Overturning Current. Based on my awkward pronunciation of the Atlantic Meridional Overturning Current, you can understand why I prefer the acronym, AMOC. With this video, I will provide an overview of the AMOC, including how it threatens to rapidly cool a significant portion of Earth. I will then explain why I’m skeptical of this outcome.
CNN published an article on 26 July 2023 titled A crucial system of ocean currents is heading for a collapse that ‘would affect every person on the planet.’ The first two paragraphs follow:
“A vital system of ocean currents could collapse within a few decades if the world continues to pump out planet-heating pollution, scientists are warning – an event that would be catastrophic for global weather and ‘affect every person on the planet.’”
“A new study published Tuesday in the journal Nature found that the Atlantic Meridional Overturning Current – of which the Gulf Stream in a part – could collapse around the middle of the century, or even as early as 2025.”
The paper was published in Nature Communications, not Nature. But I digress.
It is no exaggeration to claim that the AMOC is critical to the continued retention of habitat for life on Earth. It is a complex tangle of currents that, among other things, works like a giant conveyor belt that transports warm water from the tropics toward the North Atlantic. At this point, the water cools and becomes saltier. It therefore sinks deep into the ocean before spreading south. Importantly, the AMOC contributes to the regulation of global weather patterns. Its collapse would trigger extreme winters and rising sea levels in western Europe and the northeastern United States. Further from home, a collapsed AMOC would shift the timing and magnitude of the tropical monsoon.
