“Since dawn of this, of the modern satellite record [in] 1979, it is [been] declining for all months,” said Serreze. “September, especially. September is the end of the melting season in the Arctic, and that is when the biggest trends have occurred. Something like 13 percent per decade. It’s huge.”
The sea ice grows in the winter when the arctic is very cold and dark and then die back every summer, when the region is dunked with sunbathing sunlight. But for the entire history of humanity there has always been an Arctic sea ice that does not melt in the summer – the thick, perennial ice that Gordon Brower talked about.
And as Brower, Serreze says that it is much less of it now.
“It’s getting so hot now that it’s hard to form all this really old, thick, perennial ice, and some of [it] just melt away,” said Serreze. “But we can not really regenerate it anymore.”
This means that isis in the Arctic becomes thinner while covering a smaller area. And that is a very big thing, because one of the most important things that polaris does for all on earth is to reflect sunlight and warm back in space.
Researchers call it “albedo” ̵
1; how reflection is something. And Serreze says the icecream in the Arctic is “one of the world’s higher albedo surfaces” – a giant reflective shield that bounces heat away from us.
When the ice starts to melt, the Arctic reflects less solar energy and absorbs more of it. And that leads to a scary feedback loop: Lesser sea ice means that more of the Arctic is mostly dark sea. The dark surface absorbs more heat, which leads to more ice loss, and the process just feeds back on itself.
This is one of the reasons why the Arctic warms up so fast.
But it is not the end of the story of what changes when the Icelandic ice is disappearing.
The temperature difference between the cold Arctic and the warmer temperate zones is what drives the northern beam stream, the huge river of the wind that flows around the northern hemisphere. When arctic heat and temperature difference decrease, some researchers believe the radiation can be disturbing and sometimes send arctic blasts south and heat waves to the north.
There is still much to learn about all these processes and other effects of ice loss, but there is a bottom line: Arctic Ocean ice has helped to keep the climate of the earth in a more or less predictable way for thousands of years, and when people warming up the planet makes us harder for the ice to do it for us.
That’s why Sheila Watt-Cloutier talks about Arctic people, she can talk about us all.
“Our lives depend on ice, cold and snow” Watt-Cloutier, former head of the Inuit Circumpolar Council, advocating the many Inuit groups in the north.
Only the people who live in the Arctic look and experience it much more directly than the rest of us. And that means that much of the knowledge that people in the region have long claimed does not serve the present generation here.
“Many of our elders say,” We learn the traditional knowledge we’ve been taught about the millennium about safety, the conditions of what’s on the ice and the snow, “says Watt-Cloutier.” But they say that it is now a disclaimer as a result of climate change, where many of our elders have said, “This is what I learn … but” – and it is the disclaimer here – “the rules change.” “
Watt- Cloutier is from eastern Canada, thousands of kilometers from Utqiagvik, but she says that the changes in the Arctic affect all 150,000 Inuit people living here in eastern Russia, Alaska, Canada and Greenland.
“It’s not just the ice and the polar bears like we would lose, but all wisdom [that] should also go with that ice. And that’s the fear we have, “she said.” Our culture is so linked to everything around us, including the ice. And the ice is of course our vitality. And when it begins to go, it minimizes our ability to live as Inuit as we have known it for millennia. “
The deep and tight connection was shown during a new development of traditional Iñupiaq dance and drums in Utqiagvik. The artist’s movements were about hunting – they resembled the ski boat on the water and gently jumping from one ice river to another.
