For years, scientists have documented the rapid retreat of Arctic ice, from melting glaciers in Greenland to shrinking snow cover in far northern Eurasia. Now researchers have discovered one Arctic ice cap that appears to be literally sliding into the sea.Read full article >>
Arctic sea ice decline happened faster than expected. This has the effect of accelerating global warming because less of the Sun’s energy is reflected back into space by ice. Northern Hemisphere snow also sends some of that energy back into space. The amount of snow cover we have is also declining. The warming of the…
The National Oceanic and Atmospheric Administration released a disturbing animation today. It looks at the decline of perennial Arctic sea ice—the stuff that survives the regular summer melts—over the last three decades. The old iceShow More Summary
Arctic sea ice is getting younger and thinner -- and soon, it may disappear entirely
The carbon dioxide (CO2)-carbonate chemistry of sea-ice melt and co-located, contemporaneous seawater has rarely been studied in sea-ice-covered oceans. Here, we describe the CO2–carbonate chemistry of sea-ice melt (both above sea-ice...Show More Summary
A new video from NASA's Science Visualization Studio lets track the spiky, yet steady, decline of Arctic sea ice. The post Science Graphic of the Week: Perrenial Arctic Sea Ice Continues to Shrink appeared first on WIRED.
As the Arctic sea ice continues to melt the Canadian polar bear has begun to migrate north to take up permanent residency in Canada’s High Arctic islands, reports Yahoo. This may not seem like a bad thing, but it could very well decrease...Show More Summary
It was just a theory, but for years scientists believed what years of observation was telling them. As Arctic sea ice melted because of climate change, polar bears appeared to be inching their way toward a final refuge in the icy Canadian archipelago.Read full article >>
First up – global warming hoax update: Arctic sea ice has reached the largest December extent in a decade. Government experts will of course not acknowledge this, because their funding and reputations depend on a misinformed public and Congress. Here in Las Vegas, there is a chance we’ll have a light dusting of global warming […]
By Alex Kirby, Climate News Network As climate change increasingly affects the Arctic, some polar bear populations are suffering because rising temperatures are reducing the sea ice vital for their survival.
Right now, it's cold in the Arctic. Days are dark, and ice grows to cover the dark sea. Come summer, lengthening days and warming temperatures will reverse that process. Read the rest
NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 - a trend that aligns with the steady decrease in Arctic sea ice during the same period. read more
Air temperatures at the top of the world continue to rise twice as fast as temperatures in lower latitudes, causing significant ice melt on land and sea, and affecting populations of polar bear and migrations of fish, a federal report released Wednesday said.Read full article >>
From the “no death spiral” department comes this press release made at AGU from ESA. Arctic sea ice is holding up to global warming better than expected, according to the latest data from the CryoSat-2 satellite, a team from University College London will tell the AGU Fall Meeting in San Francisco. Arctic sea ice volumes…
The European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements. The data flies in the face of the established downward trend, but...Show More Summary
The Arctic sea ice ringed seals depend on is shrinking, making an "endangered" listing for the seals possible in the future. The post NOAA Makes Big Move To Protect Ringed Seals From Climate Change And Melting Ice appeared first on ThinkProgress.
"We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime." says marine geologist Jochen Knies. In an international collaborative project, Knies has studied the historic emergence of the ice in the Arctic Ocean. The results are published in Nature Communications. read more
By Tim Radford, Climate News Network Due to the shrinkage of the sea ice, the survival of polar bears in Canada’s Arctic Archipelago is doubtful in around 80 years’ time.
The extent of sea ice cover in Arctic was much less than it is today between four and five million years ago. The maximum winter extent did not reaching its current location until around 2.6 million years ago. "We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime." says a marine geologist.
University of Adelaide-led research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating. Published today in the Proceedings of the RoyalShow More Summary
