The green line here refers to sediment data, and the blue line refers to ice core data. What's interesting is as the blue and green lines drop dramatically throughout the time period, they coincide with Heinrich events, marked red, and DO events, which are numbered. This demonstrates an unstable AMOC in all likelihood led to these dramatic spikes.

During the Younger Dryas Period, which was a period of extreme climate change, the AMOC slowed abruptly around 12,500 years ago. This caused a period of near glacial temperatures in the Northern Hemisphere. This was caused by the melting of the Laurentide Ice Sheet, which resulted in several mass iceberg surges into the North Atlantic Ocean. They're known as Heimlich events.

At certain times, these ice sheets release large amounts of fresh water into the North Atlantic. We can see recorded evidence of these events in North Atlantic marine sediments as layers with a large amount of coarse-grained sediments derived from land.

These layers, which are continuous across large areas of the North Atlantic, are evidence for both an increase in icebergs discharged from the Laurentide Ice Sheet in North America and a southward extension of cold polar waters. Scientists have hypothesized that these freshwater dumps reduced ocean salinity enough to slow deep water formation and therefore the AMOC.

Since the thermohaline circulation plays an important role in transporting heat northward, a slowdown would cause the North Atlantic to cool. Later, as the addition of freshwater decreased, ocean salinity and deep water formation increased and climate conditions recovered. Okay, so hopefully by now you've got the general gist of this pretty large, very real problem.

So we turn to the big question of when is it going to collapse? Note my use of when here. The thing that struck me the most while recording this video is that there are so many different papers written on the AMOC, and they all have different answers to that question of when.

But the one thing they all seem to agree on is that if we continue on our current trajectory, it's no longer a question of if, but indeed when, this collapse occurs. As we stated at the start of the video, until a few years ago, the general thinking in the IPCC was the probability of crossing that tipping point this century was less than 10%.
