Climatologists have long feared an Arctic «time bomb» — a sudden release of carbon dioxide from thawing permafrost soils that would trigger runaway warming.

Lenton warned the meeting that global warming might trigger tipping points that could cause runaway warming or catastrophic sea - level rise.

Warming could conceivably also trigger a runaway release of natural stores of carbon into the atmosphere.

Each of these ecosystem collapses could trigger an out - of - control runaway warming process.

Please correct my faulty understanding, but I have read (secondary sources) that 251 million years ago it is thought there was 6 degrees global warming (from natural causes), and that this triggered massive CO2 and CH4 releases, leading to runaway global warming, and massive extinction.

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.

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.

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..

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.

«The latest scientific assessments tell us the risks of crossing critical tipping points, capable of triggering runaway climate change, rise very significantly between 1.5 ˚C and 2 ˚C warming.

There is no global harm identified due to the rise in CO2, which has been up to 20X higher in the past without ever triggering runaway global warming — the scare that started it all.

Actually I think the claim is that CO2 warming (but mysteriously not «natural» warming) triggers other positive feedbacks causing a runaway effect (I won't call it «greenhouse» because that's a misnomer).

A large injection of the gas - which is 21 times more potent as an atmospheric heat trap than carbon dioxide - has long been cited by climate scientists as the potential trigger for runaway global warming.

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 the planet warmed, large amounts of frozen methane gas under the ocean might have been released to trigger runaway greenhouse warming, Ward said.
