An Arctic ice cap’s shockingly rapid slide into the sea

4 days agoHealth : The Checkup

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 >>

Global warming’s effects are coming on faster than previously thought.

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…

Watch Arctic Sea Ice Melt Over 28 Years in One Minute

6 days agoUnited States / Seattle : Slog

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

Sea-ice melt CO2–carbonate chemistry in the western Arctic Ocean: meltwater contributions to air–sea CO2 gas exchange, mixed-layer properties and rates of net community production under sea ice (update)

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

Science Graphic of the Week: Perrenial Arctic Sea Ice Continues to Shrink

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.

Climate Change Is Pushing The Polar Bear North Putting Their Survival At Risk

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

As ice melts, polar bears migrate north

2 weeks agoHealth : The Checkup

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 >>

Friday Open Thread

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 […]

Polar Bears Feel the Heat as Icy Habitat Shrinks

last monthNews : Truthdig

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.

Insight into Arctic melting

last monthOdd : Boing Boing

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 satellites measure increase of Sun's energy absorbed in the Arctic

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

The Arctic keeps warming. And polar bears are feeling the heat.

last monthHealth : The Checkup

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 >>

Good news from #AGU14 ‘Arctic sea ice is holding up to global warming better than expected’

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…

CryoSat records small decrease in Arctic ice volume

last monthTechnology / Gadgets : Gizmag

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

NOAA Makes Big Move To Protect Ringed Seals From Climate Change And Melting Ice

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.

The emergence of modern sea ice cover in the Arctic Ocean, 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 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

Canada’s Polar Bears Face Food Crisis by 2100

2 months agoNews : Truthdig

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.

Emergence of modern sea ice in Arctic Ocean, 2.6 million years ago

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.

Better forecasts for sea ice under climate change

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
