Sentences with phrase «irreversible melting of ice sheets»

The team stresses that even a little warming could cause irreversible melting of ice sheets and turn dense Amazon forests into dry savannah grassland.

Not exact matches

This ice sheet is losing mass at a rather larger rate (around 220 cubic kilometres per year) and it will take only another 1 - 2 oC world warming to raise the summer melt zone to the top of the Greenland ice pack after which point, in my understanding, the ice sheet will go into irreversible melt.

Many important questions of environmental policy, however, involve inescapably uncertain outcomes... How much global warming will it take to trigger the irreversible collapse and melting of the Greenland ice sheet?»

Will we reach the point where the melting of the Greenland ice sheet is irreversible?

The melting of Greenland and the retreat of Antarctic ice sheets were proceeding faster than experts had expected and now looked irreversible.

At that level, the world risked initiating feedbacks in the climate system, such as the melting of ice sheet area, that could trigger irreversible warming out of humanity's control.

How such a warming would impact the probability of irreversible changes to elements of the climate system (melting ice sheets, reversal or slowing of ocean currents, release of carbon in permafrost) is unknown.

But in Bamber's second calculation the relatively sophisticated energy balance model, which he believes better represents ice sheet behaviour, gave a threshold of 8 degrees for irreversible melting of Greenland — double the previously published threshold.

But in Bamber's second calculation the relatively sophisticated energy balance model, which he believes better represents ice sheet behaviour, gave a threshold of 8 degrees for irreversible melting of Greenland - double the previously published threshold.

So scientists are keen to know at what temperature melting of the ice sheet is likely to become irreversible.

A 550 world dramatically increases the likelihood of catastrophes and runaway climate change, such as an irreversible melting of the Greenland ice sheet resulting in sea - level rise of 7 metres.

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.

For example, the weakening of the THC under 1 degree of warming, a risk of collapse for 3 degrees, risk of irreversible melting of the Greenland Ice sheet at 2 degrees warming, sea level changes of 5 — 12 meters over several centuries, — these eventualities are debatable, and should certainly be viewed as the «adverse tail» of possible impacts.
