“TWO TIPPING POINTS THREATEN TO GET CROSSED
Loss of the latent heat buffer is a tipping point that is linked to the subsequent destabilization of methane hydrates. So, there are two tipping points that are linked, and the latent heat tipping point gets crossed before the seafloor methane tipping point gets reached.
The latent heat tipping point is the point where sea ice loss is such that further incoming ocean heat that previously was consumed as Arctic sea ice melted, instead gets absorbed by the Arctic Ocean. This tipping point is estimated to correspond with a Northern Hemisphere ocean temperature anomaly of 1°C above the 20th century average.
The second tipping point occurs as more heat reaches the seafloor where it destabilizes hydrates contained in sediments at the seafloor. This tipping point comes with multiple self-reinforcing feedback loops such as explosive growth in methane volume setting off further destabilization. This tipping point will occur later, so it corresponds with a higher Northern Hemisphere ocean temperature anomaly.
Once this Latent Heat Tipping Point is crossed and as the temperature of the oceans keeps rising, more heat will reach sediments that are located at the seafloor of the Arctic Ocean and that contain vast amounts of methane.
The danger is that further heat will destabilize hydrates in these sediments, leading to explosive eruptions of methane, as its volume increases 160 to 180-fold when leaving the hydrates, and resulting in huge eruptions of methane both from the destabilizing hydrates and from methane that is present in the form of free gas underneath the hydrates.
The methane hydrates tipping point is estimated to get crossed as Northern Hemisphere ocean temperature anomaly goes beyond 1.35°C above the 20th century average.

The pink trend, based on 1850-2022 data, indicates that the Latent Heat Tipping Point was crossed in early 2022, while the red trend, which is based on 2007-2022 data and better reflects variables such as El Niño, indicates that the Latent Heat Tipping Point and the Seafloor Methane Tipping Point could both be crossed in 2024.
