Examples of components susceptible to such abrupt change are clathrate methane release, tropical and boreal forest dieback, disappearance of summer sea ice in the Arctic Ocean, long-term drought and monsoonal circulation.
Deposits of methane clathrates below the sea floor are susceptible to destabilization via ocean warming.
Anthropogenic warming will very likely lead to enhanced methane emissions from both terrestrial and oceanic clathrates.

New Finding Shows Climate Change Can Happen in a Geological Instant
The Paleocene/Eocene thermal maximum (PETM) is a climate shift that occurred 55 million years ago.
James Wright, Rutgers University Research News -
Morgan Schaller, James Wright, and the core sample
that helped them understand what happened
– and how fast it happened – 55 million years ago.
Following a doubling in carbon dioxide levels, the surface of the ocean turned acidic over a period of weeks or months and global temperatures rose by 5 degrees centigrade – all in the space of about 13 years.
“We’ve shown unequivocally what happens when CO2 increases dramatically – as it is now, and as it did 55 million years ago,” James Wright said.
The film below goes into more detail regarding the current situation.
New Film: Last Hours
The film “Last Hours” describes a science-based climate scenario where a tipping point to runaway climate change is triggered by massive releases of frozen methane. Methane, a powerful greenhouse gas, has already started to percolate into the open seas and atmosphere from methane hydrate deposits beneath melting arctic ice, from the warming northern-hemisphere tundra, and from worldwide continental-shelf undersea methane pools.
“Last Hours” is narrated by Thom Hartmann and directed by Leila Conners. Executive Producers are George DiCaprio and Earl Katz.

High Methane Levels persist over Arctic Ocean
High methane levels are prominent over the Arctic Ocean, as illustrated by the image below, covering a period from October 3, 2013, 10:54 am to October 7, 2013, 11:53 pm. The fact that methane has not been present elsewhere in such high concentrations over this period indicates that the methane wasn't carried there by the wind from elsewhere. Also, methane typically appears to move along the same latitude, due to the Coriolis effect.
The image indicates a link between seismic activity and destabilization of methane that is held in sediments under the Arctic Ocean. Methane does show up prominently along the fault line that crosses the Arctic Ocean and extends into Siberia over the Laptev Sea.
The Diagram that IPCC failed to include in AR5
The diagram below shows global warming evolving into accelerated warming in the Arctic. Feedbacks such as albedo changes and methane release speed up this process, triggering abrupt climate change and finally extinction.

Post by Sam Carana.
Some have suggested that an independent panel to the IPCC should be set up given the gravity of the Arctic situation. IPCC analysis is just too casual and simply does not convey the serious consequences of Arctic melt. Are you aware of any such initiatives? There are surely enough experts in the scientific field. Peter Wadhams is an outstanding spokesman, but even he is not being listened to.
Also I assume you have seen this:
Nowhere do they mention the effects of albedo loss, have I understood that correctly?
Yes, I'm keen to support any international panel that is willing to take a close look at the situation in the Arctic and articulate the effective and comprehensive action that is necessary to stave off climate catastrophe.Delete
Well if people don't do anything Extinction is written in stone. In fact it may well be impossible to get ahead of the curve and restore margin for error. Economy can frame to encourage best use of industrial capacity and tech for maximizing human potential towardDelete
But not simply by making small adjustments using present broken system. A locked in system that will come crashing down in a span of WAR. A link between politics and war is tied in with economics the way things stand now. That needs fundamental alteration tapping Act of God to alter contract law now..
