It would seem to be required that very drastic warming of the deep ocean is the only way that this source of Methane would be released and trigger a «runaway» greenhouse warming.

Past mass extinctions caused by runaway GW (then, obviously, triggered by a convergence of natural events), resulting in few left to breath out CO2 (among other constraints), leading to stabilization and retreat back to a climate more hospitable to a wide range of biota.

BACK TO TOPIC: If CO2 & CH4 are important forcings in a linear GW scenario, then in a «runaway» GW scenario of the warming triggering further mechanisms of warming, triggering further mechanisms, our anthropogenic GHG emissions have even more ultimate impact.

And if we reach just shy of 3C warming (or whatever the tipping point is) by 2100 or 2200 (but do not trigger limited runaway warming or hysteresis), that by at least 2000 years from now the sea level would have risen about 30M.

A «runaway greenhouse effect» occurs when something warms the planet, triggering positive feedbacks which warm it further; however, even this does not mean the planet continues warming infinitely, forever.

One of the biggest debates between sceptics and their counterparts is in fact the role played by feedback mechanisms — a response in part to claims by environmentalists such as Mark Lynas in «Six Degrees: our future on a hotter planet» that a relatively small increase in CO2 could cause «runaway climate change» by triggering (unknown and possibly non-existent) feedback mechanisms to form.

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..

And I would think a runaway greenhouse effect could in principle be triggered by more than just a simple temperate - tipping point - it could also be caused by an excessively quick rise in temperature.

Per the IPCC's global warming hypothesis, at the very top of the troposphere, above the equator region, is the location (12 km, 200hPa @ 20 ° N - 20 ° S) that triggers a positive climate feedback, which produces the mythical runaway, tipping point of accelerated, dangerous global warming, which of course is unequivocal and irrefutable, except when it isn't.

In fact, if we are really seeing runaway feedbacks triggered after the less than one degree of warming we have had over the last century, it boggles the mind how the Earth has staggered through the last 5 billion years without a climate runaway.

As far as I can tell, Hansen's notion that if we really go to town using fossil fuels, we might trigger a true runaway greenhouse effect just seems rather vaguely - supported by any detailed argument or evidence at this point and does not seem to be the general belief within the climate science community.

While the headline this time is more restrained — «Runaway greenhouse effect possible but difficult» — the first paragraph rather breathlessly announces that a runaway greenhouse effect would be «easier» to trigger than was previously beRunaway greenhouse effect possible but difficult» — the first paragraph rather breathlessly announces that a runaway greenhouse effect would be «easier» to trigger than was previously berunaway greenhouse effect would be «easier» to trigger than was previously believed.
