Antarctic Ice Melting faster than ever, Studies Show

That exact location matters, as the communities living on the US coastline will see the sea levels rise, according to climate scientists. The rate at which Antarctica is losing ice has more than doubled since 2012, according to the latest available data.

"Satellites have given us an fantastic, continent-wide picture of how Antarctica is changing", said study co-author Dr. Pippa Whitehouse.

The threefold increase in ice loss from the continent as a whole is a combination of glacier speedup in West Antarctica and at the Antarctic Peninsula, and reduced growth of the ice sheet in East Antarctica.

"We have long suspected that changes in Earth's climate will affect the polar ice sheets", Andrew Shepherd, climate scientist at the University of Leeds, said in a news release. Marine-based ice is already starting to add to sea level rise and alone could contribute as much as 20 meters.

In the last quarter century, the southern-most continent's ice sheet - a key indicator of climate change - melted into enough water to cover Texas to a depth of almost 13 feet (4 meters), scientists calculated. "Thanks to our satellites our space agencies have launched, we can now track their ice losses and global sea level contribution with confidence". Sea level rise is a threat to cities from NY to Shanghai as well as low-lying nations from the Pacific Ocean to the Netherlands.

"I don't know if it's going to keep exactly tripling, but I think it has a lot of potential to keep significantly increasing", said Velicogna. U.S. President Donald Trump plans to pull out of the pact and to focus instead on U.S.jobs and coal.

The Antarctic ice sheet covers about 24 million square kilometres and holds about 60 per cent of all freshwater on Earth. "This paper suggests it is stretching its limbs".

The result also reinforces that nations have a short window - perhaps no more than a decade - to cut greenhouse gas emissions if they hope to avert some of the worst consequences of climate change.

"Our study underlines the importance of understanding the mechanisms driving these sea ice trends, particularly in regions where sea ice acts as a protective buffer against ocean processes", he said. By mapping our measured sea level contribution on top of these projections, we found that our previous assessment of Antarctic sea level contribution, which measured ice loss until 2012, was tracking the IPCC's lowest projection.

Technology can also be redesigned to rejuvenate the environment.B ut the most important step which can be taken regarding pollution is that the policymakers make it a priority to keep an environment check and find better policies which could help us to live in a stable environment.

In West Antarctica, ice shelves are being eaten away by warm ocean water, and those in the Amundsen and Bellingshausen seas have thinned by as much as 18 percent since the early 1990s. He blames the burning of coal, oil and natural gas as the cause of global warming.

The analysis suggests that 3 trillion tons' worth of Antarctic ice losses have increased global sea levels by 7.6 mm (0.3 inches) since 1992, and that the increase is accelerating.

The next 10 years will be critical for the future of Antarctica, and choices made will have long-lasting consequences, says an global group of award-winning Antarctic research scientists in a paper released Thursoday.

Greenpeace which is campaigning for a large tract of the ocean surrounding the Antarctic to be made into the world's biggest ocean sanctuary, said government's must heed the warning.
