How the Arctic ice cap may shrink by another 40 percent in the coming decades
By The Associated Press article BAYSTOR, Alaska (AP) It’s a tale of two ice sheets.
The first is melting faster and more deeply.
The second is retreating faster and deeper.
The two are a direct result of two very different trends: The Arctic’s ice cap is rapidly melting, and its retreating.
The trend started with global warming, when more than 70 percent of the ice melted during the late 1990s and early 2000s.
It accelerated last decade, when a huge chunk of the globe became uninhabitable by humans and ecosystems.
As temperatures have soared and Arctic sea ice dwindles, the ice is retreating, too.
The shrinking ice caps could cause major disruptions in global trade, shipping, shipping lanes and global energy supply.
The loss of the Arctic’s last ice cap, known as the Kara Sea, is already affecting shipping lanes, transportation, energy and other critical sectors, experts said.
The Kara Sea is expected to shrink by 40 percent to 65 percent of its volume in 2040 and then fall even further, said Peter Wadhams, a researcher with the British Antarctic Survey.
Wadhams said his research indicates that the ice cap’s rapid melt and retreat could also have a profound effect on global weather patterns.
Wadi Hamdan, a former British ice-breaker captain who was awarded the Order of St. George in 2011, said the Kara sea has become more vulnerable to rising seas.
He said the sea ice has dropped by half since it was first observed in 1992.
The Kara Sea was once the world’s largest body of water.
But in 2016, it became the second-most-damaged in the world, behind only the Great Barrier Reef.
The impact is felt across the region.
The effects of the Kara’s thinning ice cover are obvious to anyone with a camera.
The ocean is less covered and it is more exposed to the sun’s rays.
The ice itself melts much faster, and more quickly.
Wadi Hamadans team has seen the effects of that melting firsthand.
He and his team have measured the changes on a daily basis.
In January, Wadham said, the Kara had lost around 1,000 square miles of sea ice, which was almost 10 percent of it in the 1990s.
The melt covered nearly a quarter of the sea.
The ice cover, Wadgan said, is shrinking more quickly than any other part of the ocean.
He noted that this loss has been driven by a combination of two factors.
First, global warming.
This year alone, the Earth experienced more than 1,600 billion metric tons of warming, according to the Intergovernmental Panel on Climate Change.
Second, Arctic sea-ice melt is also speeding up, Wadahms said.
The amount of sea- ice lost in the past decade has doubled, and scientists expect that it will continue to do so for the foreseeable future.
This summer, the Arctic Ocean lost more than half its ice cover.
Wads said this trend could be accelerating as the Arctic warms, because melting ice is becoming denser, making it harder to get rid of it.
In a new study, Wadsworth and his colleagues report that Arctic sea water temperatures have increased by 0.6 degrees Fahrenheit since 1990, but that the sea surface temperature has increased by only 0.3 degrees Fahrenheit.
That’s because warmer air is floating more, which cools the water, Wadithan said.
It’s a very rapid rate of warming.
And it is already having an effect.
Wada Hamdan of the British Arctic Maritime Museum said he believes Arctic sea temperatures are likely to increase even faster, as temperatures rise more quickly and the sea becomes more exposed.
The study also indicates that Arctic ocean temperatures could rise by as much as 6 degrees Celsius by 2040.
That could cause disruptions in the region’s supply of water, energy, raw materials and raw materials that support life.
Wadham said the effect of climate change on the Kara is a real concern.
The melting ice could also disrupt the flow of energy in the Kara, and the energy will come from melting ice.
“We are talking about a massive amount of energy,” Wadham added.
Wada Hamadan said the effects could be severe, because the Kara will be vulnerable to the effects from global warming as well as from the loss of its ice.
“It’s going to be a big thing,” he said.
Wadal said the melting of the Siberian ice cap has been particularly troubling.
The area of the region where the melt occurred was the biggest in the United States in 2016.
It’s the biggest loss of ice in the Arctic in 20 years, Wadahan said.
That has been blamed on global warming and the decline of the permafrost in the area.
The rapid melting and retreating of the Alaska Arctic Shelf, which is the region of the Ross Sea and the Beaufort Sea that lies between the Kara and the Siberian coasts, has also been the subject of concern for Wad
