The ice caps of Antarctica are melting at a faster rate than previously thought, a new study has found.
The new research was conducted by researchers at the University of Edinburgh’s Antarctic Research Unit, the National Oceanography Centre, and the US National Snow and Ice Data Centre.
“It’s not just the ice that’s melting,” said lead author Dr. Thomas Kallenberg, a research scientist at the Antarctic Research Centre.
“The ice is melting faster, and in some cases faster than people thought.”
“We have to understand why.”
Researchers found that the Antarctic ice sheet was melting faster during the summer of 2016, and that this had a profound impact on the ocean’s ability to absorb the heat from the sun.
“The melt rate in Antarctica is accelerating,” Dr. Kallenburg told Al Jazeera.
“There is no doubt that in summer, Antarctica is warming faster than it has in decades.
We now have to ask why.
The answer is that the ice sheet is melting.”
Dr. Kalmann says the melting rate in the Antarctic was significantly higher during the Summer of 2016 than in the Summer the previous year.
“When the ice is frozen and it melts, it’s like a sponge, and it absorbs water from the air and the water in the air gets carried away, which leads to the melting of the ice.”
This has an effect on the sea level because the ice melts, and if the sea is higher, then the sea also gets higher,” he said.
The study also found that summer melt rate was the same for the Antarctic Peninsula and the Antarctic Ocean, suggesting that the two regions had similar melting rates.”
At the Antarctic level, the ice volume is melting at about 3.5 metres per year, and at the ocean level it is melting about 1.8 metres per day,” said Dr. Keating.”
That’s a pretty significant difference, and not something we expect to see in the future.
“The researchers also found evidence that the summer melting rate of Antarctica had slowed, and now remained stable, compared to the summer 2016 melt rate.”
As you can see in this image, the summer melt is the same.
We don’t see it slowing down,” said Prof. Thomas O’Brien, a researcher at the US Antarctic Division.”
We’re not seeing an acceleration of the melt rate, it has not increased, but the summer rate is stable and has not changed much.
The ice has been growing.
“The new study suggests that this is likely to be a result of warmer waters absorbing the heat and therefore reducing the amount of heat released into the ocean.
The researchers analysed the data from satellites, measuring the amount and direction of sunspot activity, sea surface temperature and ocean temperature.
The data revealed that Antarctica was experiencing more and more solar activity, and therefore had an increased heat content.
This in turn meant the Antarctic had more meltwater, which in turn caused more water to be pushed up the ice sheets.
The ice caps were also melting faster when it was warmer.”
What we have found is that over the last 10 years, the average rate of the melting is higher and the average amount of ice is lower than it was a few years ago,” said Professor Kallheim.”
I think that’s likely because we’re getting warmer and we’re also getting more sunlight.””
It was very surprising to see that the melting rates have gone up, but there is a lot more ice to melt,” said Thomas Kalle, a scientist at University of Aberdeen’s Institute of Marine Science.”
For me, it is a little bit of a disappointment.
I think we would expect this, given the amount we have had to go through, to increase.
“The authors of the study, published in Nature Communications, also found significant evidence that melting was accelerating in the Atlantic Ocean, which they believe is related to increased sunlight being absorbed by the ocean surface.”
Our research shows that the Arctic is melting more rapidly than previously expected, and this has implications for the global warming situation,” said Alastair Cook, director of the UK’s Department of Energy and Climate Change (DECC), who led the study.”DECC has been urging the UK government to increase the deployment of solar thermal systems, but these new results suggest that they should consider an option of increasing solar thermal installations, rather than just relying on the existing energy storage systems.””
The study was published in the journal Nature Communications.”
DECC will continue to monitor these developments to assess the potential for future applications and to work with other agencies to further develop our solar thermal technologies and our photovac technology.”
The study was published in the journal Nature Communications.
