Arctic sea ice drops to 2nd lowest level on record
August 29, 2008
WASHINGTON – More ominous signs Wednesday have scientists saying that a global warming “tipping point” in the Arctic seems to be happening before their eyes: Sea ice in the Arctic Ocean is at its second lowest level in about 30 years.
The National Snow and Ice Data Center reported that sea ice in the Arctic now covers about 2.03 million square miles. The lowest point since satellite measurements began in 1979 was 1.65 million square miles set last September.
With about three weeks left in the Arctic summer, this year could wind up breaking that previous record, scientists said.
Arctic ice always melts in summer and refreezes in winter. But over the years, more of the ice is lost to the sea with less of it recovered in winter. While ice reflects the sun’s heat, the open ocean absorbs more heat and the melting accelerates warming in other parts of the world.
Sea ice also serves as primary habitat for threatened polar bears.
“We could very well be in that quick slide downward in terms of passing a tipping point,” said senior scientist Mark Serreze at the data center in Boulder, Colo. “It’s tipping now. We’re seeing it happen now.”
Within “five to less than 10 years,” the Arctic could be free of sea ice in the summer, said NASA ice scientist Jay Zwally.
“It also means that climate warming is also coming larger and faster than the models are predicting and nobody’s really taken into account that change yet,” he said.
Five climate scientists, four of them specialists on the Arctic, told The Associated Press that it is fair to call what is happening in the Arctic a “tipping point.” NASA scientist James Hansen, who sounded the alarm about global warming 20 years ago before Congress, said the sea ice melt “is the best current example” of that.
Last year was an unusual year when wind currents and other weather conditions coincided with global warming to worsen sea ice melt, Serreze said. Scientists wondered if last year was an unusual event or the start of a new and disturbing trend.
This year’s results suggest the latter because the ice had recovered a bit more than usual thanks to a somewhat cooler winter, Serreze said. Then this month, when the melting rate usually slows, it sped up instead, he said.
The most recent ice retreat primarily reflects melt in the Chukchi Sea off Alaska’s northwest coast and the East Siberian Sea off the coast of eastern Russia, according to the center.
The Chukchi Sea is home to one of two populations of Alaska polar bears.
Federal observers flying for a whale survey on Aug. 16 spotted nine polar bears swimming in open ocean in the Chukchi. The bears were 15 to 65 miles off the Alaska shore. Some were swimming north, apparently trying to reach the polar ice edge, which on that day was 400 miles away.
Polar bears are powerful swimmers and have been recorded on swims of 100 miles but the ordeal can leave them exhausted and susceptible to drowning.
And the melt in sea ice has kicked in another effect, long predicted, called “Arctic amplification,” Serreze said.
That’s when the warming up north is increased in a feedback mechanism and the effects spill southward starting in autumn, he said. Over the last few years, the bigger melt has meant more warm water that releases more heat into the air during fall cooling, making the atmosphere warmer than normal.
On top of that, researchers were investigating “alarming” reports in the last few days of the release of methane from long frozen Arctic waters, possibly from the warming of the sea, said Greenpeace climate scientist Bill Hare, who was attending a climate conference in Ghana. Giant burps of methane, which is a potent greenhouse gas, is a long feared effect of warming in the Arctic that would accelerate warming even more, according to scientists.
Overall, the picture of what’s happening in the Arctic is getting worse, said Bob Corell, who headed a multinational scientific assessment of Arctic conditions a few years ago: “We’re moving beyond a point of no return.”

Scientists think that global warming in the Arctic Ocean is getting worse. The ice is at its second lowest level in thirty years, but with three weeks left in the Arctic summer this year could wind up breaking the record. Within five to ten years the Arctic could be free of sea ice in the summer. This fact greatly affects polar bears whose primary habitat is sea ice. The melt has also kicked in another effect called Arctic amplification. Scientists say that we are moving beyond a point of no return.
This article is explaining how Artic sea ice is droping very low. This sea ice has dropped to its 2nd lowest ever. The National Snow and Ice Data Center said that the ice covers only 2.03 million sqaure miles.This is also putting the polar bears in serious danger. Federal observers saw 16 polar bears swimming north trying to reach the polar ice edge. On that day the polar ice edge was an amazing 400 miles away. This will be a long trek for the polar bears. Global warming is happening way faster than the models were predicting. Everyone needs to become more aware of global warming.
After 30 years, the Artic Ocean has reached a second all time low of 2.03 million square miles of ice coverage. The problem is just coming to light even though it was protested 20 years ago. Normally around this time of year the ice would be forming back, but now it is expected to melt drastically in the next three weeks. With the ice loss it is also effecting wild life, polar bears, even though are great swimmers, cannot live without the ice. Last year, when this same disaster occured scientist hoped it was just a one time thing. But now it is proved that if the we do not change our lives electrically, in the next 5-10 years the Artic could be just another normal ocean.
Scientist think global warming may be an upcoming problem. It continues
to get worse and sea ice is at its second lowest level in 30 years. Sea ice only takes up 2.03 million square miles. (The lowest being in 1979 with 1.65.) With three weeks left of summer, scientists say this could end up breaking the older record. Possibly in the next 5 to 10 years artic ice could be in the history books scientist say. Arctic warming is coming much faster than predicted.
Sceintist say that there may be a global warming in the Artic Ocean.It keeps getting worse.The sea ice has been at one of its lowest levels in 30 years.With three weeks of left of summer , sceintist say this could end up breaking the older record.Sceintist say that in the next five to ten years the Artic ice could be history.It is also affecting the wildlife there.
Scientists think that global warming is taking its toll on the Arctic. The sea ice is at its second lowest level in about 30 years. Sea ice is the primary habitat for polar bears as well. That is part of the reason why they are endangered. The scientists believe that global warming is past its tipping point and things are getting out of hand. I really learned a lot from this article.
This article is about how the Artic sea is dropping very low. The Artic sea has dropped to its 2nd lowest ever. years. The National Snow and Ice Data Center reported that sea ice in the Arctic now covers about 2.03 million square miles. Sea ice also is hurting the polar bears which are putting them in danger.

They we apparently trying to reach the polar ice edge, which on that day was 400 miles away. Global warming is getting worse and worse and people need to be aware of it and try to help stop it.

This article is telling us that the Arctic sea is dropping to a low level. This sea ice has dropped to its 2nd lowest level in thirty years. There is about three weeks left in the Arctic summer, scientists said it could wind up breaking the record before. The Arctic could be free of sea ice within five to ten years. The melt in sea ice has kicked in an effect called Arctic amplification. That’s when the north’s warming is increasing in a feedback mechanism and the effects spill southward.

In this article, it talks about how the Arctic Sea level is at its 2nd lowest than it has been in about 30 years. With about three weeks left of summer, scientists think it might end up breaking a record! One scientist predicts that within 5-10 years the Arctic Sea could be rid of ‘Sea ice.’ This is exactly what global warming does to the planet. If it keeps going at its pace, polar bears might be stuck without any ice to live on. It would help a lot more if people could do the slightest thing about it.

4 the polar bears are now endangered because of lack of ice
5 the ;last few years the arctic has gotten back some ice
Scientists are saying that global warming in the Arctic are at the tipping point. Every year during the summer ice will melt away and refreeze in the winter. When ice melts and goes onto the sea we recover less each year. This is causing the polar bears to become extinct. Fortunately this year the ice recovered a little bit more than last time. However this did not help the polar bears much because federal observer flying for a whale survey saw nine polar bears swimming in the open. Overall global warming is getting worse.
