Sentences with phrase «irreversible melting»
"Irreversible melting" means that something is being heated or warmed to the point where it liquefies, and this change cannot be reversed or undone. Once it has melted, it cannot go back to its original solid form. Full definition
Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase.

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.
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.
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.
The team stresses that even a little warming could cause irreversible melting of ice sheets and turn dense Amazon forests into dry savannah grassland.
Glaciologists have announced that a huge ice stream in western Antarctica, recognised as the largest single contributor of ice to the sea, has begun an accelerated and irreversible melt rate that could see it shedding 100 billion tonnes a year, equating to a global sea level rise of up to 10 mm in 20 years.
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.
Soon we will have begun an irreversible melting of the Greenland icesheet and if that happens that will have very significant effects on the climate, well pretty much indefinately.
There is a significant if not readily quantifiable risk that a warming of even less than 2ºC could trigger the irreversible melting of the Greenland and West Antarctic Ice Sheets.
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.
