A global catastrophic risk is a hypothetical future event that has the potential to damage human well-being on a global scale. Some events could cripple or destroy modern civilization. Any event that could cause human extinction is known as an existential risk.

• Most ominously, the AMOC shutting down will speed up the melting of more methane clathrates on the sea floors around the world. Daily Kos
• The IPCC thinks it's unlikely that clathrate emissions will cause substantial warming in the next few centuries. 80,000 Hours
• Pluto's heat puzzle might involve a clathrate layer. Universe Today
• There is a small chance of a massive methane burst coming from permafrost melt in Siberia or the East Siberian Arctic Sea (ESAS) methane clathrates that could radically increase global methane in 2022. www.climatedisaster.net
• One could consider an initial configuration without methane molecules in the hydrocarbon phase, which would allow researchers to study the role played by the AA layer in clathrate hydrate dissolution. Nickel
• Clathrate hydrates and HNGBs could provide a reasonable mid-term solution for storing what is known as blue hydrogen, which is hydrogen produced using fossil fuel-based technology but with minimal CO 2 emissions. Hydrogen View
• Because of the enormous amounts of time required for clathrate hydrates to form and dissociate at cryogenic temperatures, it has proven very difficult to conduct experiments on Earth to predict their presence in other celestial bodies. EurekAlert!
• Some 1.1°C or 2°F of warming could result from methane releases from clathrates at the seafloor of the world's oceans. arctic-news
