What is concerning is the possibility that rapid global warming could occur faster than many people believe is possible, if global warming due to atmospheric carbon dioxide causes the Earth's atmosphere to warm enough to release enormous deposits of frozen methane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human ExtinMethane Gas Releases Due To Global Warming Could Cause Human Extinction).

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

James Hansen, adjunct professor, Department of Earth and Environmental Sciences, Columbia University and former Head of the NASA Goddard Institute for Space Studies claims the melting ice could lead to the point where ocean floor warming triggers massive release of methane hydrate, i.e., methane molecules trapped in ice crystals, which would become a «tipping point.»

Methane that escapes the sea is generally a small fraction of methane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the oMethane that escapes the sea is generally a small fraction of methane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the omethane that is released from clathrates at the sea floor, though if the concentration rose high enough so much could make it to the atmosphere that the impact of methane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the omethane as a GHG in air (before it devolves to CO2 in air) overwhelmed the negative effects of methane decomposing to CO2 in the omethane decomposing to CO2 in the oceans..

The areal extent of methane - rich sediments is fairly well known from seismic observations of this feature, but uncertainty in the concentration of methane in those sediments is very large, thus resulting in the large uncertainty in the global inventory of ocean - floor methane.

However, the hydrate stability zone thickness decreases to zero near the top of its depth range in the ocean, and an increase in water column temperature there could eliminate the stability zone entirely, potentially providing an easier pathway for methane to reach the sea floor.
