It brings less salt to the region, which then slows down the AMOC further. One of the most interesting things in this crazy cycle of ocean systems and currents is that the AMOC has a bit of a track record of being less than stable. In other words, it's collapsed before. And its collapse has historically been linked to some pretty extreme climate events.

I sometimes forget that we're still in an ice age, albeit an interglacial one, but the climate during the last glacial period was also far from stable. To give us a clue into past AMOC behaviour, we can examine some dramatic climate changes that have happened in the recent past. Recent that is from a paleoclimate perspective, the last 100,000 years or so.

One thing we know from studying the paleoclimate is that some of the most abrupt and striking temperature changes are periods of abrupt warming followed by a period of slow cooling that occurred during the last ice age. They were likely caused by instability in the amok. This graph shows temperature reconstructions from ocean sediments and Greenland ice over the last 60,000 years.

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.
