The melting of part of an ice sheet in Greenland is nearing tipping point and further environmental damage could follow, researchers said.
Analysis of the Jakobshavn drainage basin revealed that the central-western Greenland ice sheet is reaching a stage from which it cannot recover.
Data indicated that a critical threshold has been reached after a century of accelerated melting.
"We might be seeing the beginning of a large-scale destabilisation, but at the moment we cannot tell, unfortunately," said Dr Niklas Boers from the Potsdam Institute for Climate Impact Research, one of the two authors of the research.
"So far, the signals we see are only regional, but that might simply be due to the scarcity of accurate and long-term data for other parts of the ice sheet."
Dr Boers and Martin Rypdal from the Arctic University of Norway concluded that this part of the Greenland ice sheet is losing stability, and is very close to tipping into a state of accelerated melting, PNAS said on Monday.
Should that scenario play out, it will not be possible to save the sheet even if the Arctic warming trend was halted in the coming decades.
An ice sheet can only maintain its size if the loss of mass from melting is replaced by snow falling on to its surface. The warming of the Arctic disrupts that cycle.
As the surface of the ice is exposed to higher temperatures, it leads to more melting, height reductions and accelerated loss of mass.
After a point, this process cannot be reversed because a much colder climate would be needed for the ice sheet to regain its original size.
"We need to monitor the other parts of the Greenland ice sheet more closely, and we urgently need to better understand how different positive and negative feedback might balance each other, to get a better idea of the future evolution of the ice sheet," Dr Boers said.
The work is part of the Tipes project, co-ordinated and led by the University of Copenhagen in Denmark and the Potsdam institute in Germany.

Employment lawyer Meriel Schindler of Withers Worldwide shares her tips on achieving equal pay
Do your homework
Make sure that you are being offered a fair salary. There is lots of industry data available, and you can always talk to people who have come out of the organisation. Where I see people coming a cropper is where they haven’t done their homework.
Don’t be afraid to negotiate
It’s quite standard to negotiate if you think an offer is on the low side. The job is unlikely to be withdrawn if you ask for money, and if that did happen I’d question whether you want to work for an employer who is so hypersensitive.
Know your worth
Women tend to be a bit more reticent to talk about their achievements. In my experience they need to have more confidence in their own abilities – men will big up what they’ve done to get a pay rise, and to compete women need to turn up the volume.
Work together
If you suspect men in your organisation are being paid more, look your boss in the eye and say, “I want you to assure me that I’m paid equivalent to my peers”. If you’re not getting a straight answer, talk to your peer group and consider taking direct action to fix inequality.

Freezer tips
- Always make sure food is completely cool before freezing.
- If you’re cooking in large batches, divide into either family-sized or individual portions to freeze.
- Ensure the food is well wrapped in foil or cling film. Even better, store in fully sealable, labelled containers or zip-lock freezer bags.
- The easiest and safest way to defrost items such as the stews and sauces mentioned is to do so in the fridge for several hours or overnight.

Types of policy
Term life insurance: this is the cheapest and most-popular form of life cover. You pay a regular monthly premium for a pre-agreed period, typically anything between five and 25 years, or possibly longer. If you die within that time, the policy will pay a cash lump sum, which is typically tax-free even outside the UAE. If you die after the policy ends, you do not get anything in return. There is no cash-in value at any time. Once you stop paying premiums, cover stops.
Whole-of-life insurance: as its name suggests, this type of life cover is designed to run for the rest of your life. You pay regular monthly premiums and in return, get a guaranteed cash lump sum whenever you die. As a result, premiums are typically much higher than one term life insurance, although they do not usually increase with age. In some cases, you have to keep up premiums for as long as you live, although there may be a cut-off period, say, at age 80 but it can go as high as 95. There are penalties if you don’t last the course and you may get a lot less than you paid in.
Critical illness cover: this pays a cash lump sum if you suffer from a serious illness such as cancer, heart disease or stroke. Some policies cover as many as 50 different illnesses, although cancer triggers by far the most claims. The payout is designed to cover major financial responsibilities such as a mortgage or children’s education fees if you fall ill and are unable to work. It is cost effective to combine it with life insurance, with the policy paying out once if you either die or suffer a serious illness.
Income protection: this pays a replacement income if you fall ill and are unable to continue working. On the best policies, this will continue either until you recover, or reach retirement age. Unlike critical illness cover, policies will typically pay out for stress and musculoskeletal problems such as back trouble.
Soldier F
“I was in complete disgust at the fact that only one person was to be charged for Bloody Sunday.
“Somebody later said to me, 'you just watch - they'll drop the charge against him'. And sure enough, the charges against Soldier F would go on to be dropped.
“It's pretty hard to think that 50 years on, the State is still covering up for what happened on Bloody Sunday.”
Jimmy Duddy, nephew of John Johnson
