NASA has said that we have passed a tipping point with the West Antarctic Ice Sheet Sheet (WAIS) and its collapse is now «unstoppable».

Thus, the concept of an emissions budget is very useful to get the message across that the amount of CO2 that we can still emit in total (not per year) is limited if we want to stabilise global temperature at a given level, so any delay in reducing emissions can be detrimental — especially if we cross tipping points in the climate system, e.g trigger the complete loss of the Greenland Ice Sheet.

I think that this record also shows a significant tipping point scenario at ~ 12, ~ 22 and ~ 34 Myr bp with the formation and disintegration of the Antarctic ice sheet.

Some prominent individuals have suggested that the disintegration of the West Antarctic Ice Sheet is part of an overall climate «tipping point.»

A related alternative metaphor, perhaps less objectionable while still making the most basic point, comes to mind in connection with an image of crashing of massive ice sheets fronts into the sea — an image of relevance to both climate tipping points and consequences (sea level rise).

-LSB-[Some prominent individuals have suggested that the disintegration of the West Antarctic Ice Sheet is part of an overall climate «tipping point.»

As intriguing a concept as it is, a «tipping point» is less useful if poorly defined quantitatively or largely unknown, as apparently is the case with two key examples that you cite: thermohaline circulation and substantial melting of ice sheets leading to «dangerous» sea level rise.

A rise in temperature to the point where the earth's ice sheets and glaciers melt is only one of many environmental tipping points needing our attention.

Lifting off from the Greenland ice sheet, a possible tipping point Image: Brocken Inaglory via Wikimedia Commons

As Dr Hansen points out in that article, ice sheet melting is non-linear but the scientists want to draw straight lines and ignore any tipping points.

After a careful reassessment of climate sensitivity and climate history data, NASA climate science chief James Hansen and his colleagues concluded that the tipping point at which substantial ice - sheets on Earth will disappear is around 450ppm (+ / -100 ppm) of CO2.

The risk of crossing thresholds in tipping points in the Earth system (e.g. West Antarctic ice sheet disintegration and Amazon dieback) increase

This means that the CO2 levels often associated with a 2 ˚C rise — 450ppm — may just be the tipping point for the total loss of all ice sheets on the planet and a huge sea - level rise.

A rise of 2 ˚C over pre-industrial temperatures will initiate large climate feedbacks in the oceans, on ice - sheets, and on the tundra, taking the Earth well past significant tipping points.

Already 80 per cent by volume of summer sea - ice has been lost, and regional warming of up to 5 ˚C may have already pushed the Greenland ice - sheet past its tipping point.

There are apparent tipping points to sea level and CO2 levels indicating levels at which various ice sheets tip.

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..

Two of the most worrisome for scientists are tipping points with the Greenland and Antarctic ice sheets.

The Greenland ice sheet is poised for another record melt this year, and is approaching a «tipping point» into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers.

The likelihood of the complete loss of Arctic summer sea ice by 2030, faster melting of the vast Greenland ice sheets, and the rapid and quickening thaw of permafrost regions indicate that the window for arresting climate change before tipping points are reached is rapidly closing.

and his co-authors concluded in a 2008 research paper that the tipping point for the presence, or absence, of any substantial ice - sheets on Earth is around 450 ppm (plus or minus 100 ppm) of CO2.

The report predicts that half of the world's identified tipping points — such as the collapse of polar ice sheets and the drying out of the Amazon rainforest — would be crossed under 2 ℃ warming, compared with 20 % of them at 1.5 ℃.

The slowdown in this current, the study finds, is unprecedented in hundreds to perhaps as long as 1,000 years, and is most likely related to another tipping point, which is the melting of the Greenland ice sheet.

«We don't know where the ice - sheet collapse tipping point is, but we are dangerously close.»

In a 200 - page report, the scientists call for an early - warning system that would watch bellwethers like Midwestern aquifers, Antarctic ice sheets and tropical coral reefs for signs that a «tipping point» is coming.

According to Jonathan Bamber of the University of Bristol, UK, speaking at the Copenhagen session on tipping points, that makes the process pretty much irreversible once it's started in earnest - you'd need a very substantial cooling for the ice sheet to return.

Most of that ice is — for now — stable, but scientists are concerned that the massive West Antarctic Ice Sheet, which holds about 11 feet of potential sea level rise, has reached a tipping point and will collapse.

Tipping points occur because of amplifying feedbacks... Climate - related feedbacks include loss of Arctic sea ice, melting ice sheets and glaciers, and release of frozen methane as tundra melts.

We also discuss why, in contrast to Arctic summer sea ice, a tipping point is more likely to exist for the loss of the Greenland ice sheet and the West Antarctic ice sheet.

The greatest threats are tipping the Arctic sea - ice and the Greenland ice sheet, and at least five other elements could surprise us by exhibiting a nearby tipping point.

Hansen notes that «we probably need a full court press on both CO2 emission rates and non-CO2 forcings, to avoid tipping points and save Arctic sea ice and the West Antarctic ice sheet.»

Among the global - scale tipping points identified by earth scientists are the collapse of large ice sheets in Greenland and Antarctica, changes in ocean circulation, feedback processes by which warming triggers more warming, and the acidification of the ocean.h

This could prevent catastrophic, irreversible tipping points such as the melting of Arctic sea ice and the Greenland ice sheet, and buy time for implementation of critical strategies to cut long - lived greenhouse gas emissions.

Jim D, if you and others like you aren't willing to do what must be done to greatly increase the price of carbon, then all your talk of ice sheet melting, sea level rise, climate tipping points, global temperature trends, the earth's paleoclimate history, and climate model projections — all of that talk is mere Kabuke theater.

As ice sheets melt, deep water formation and ocean circulation are probably vulnerable to a critical tipping point as well.
