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 weekNews : 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 weekOdd : 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 weekHealth : 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

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

3 weeks 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

BBC Says Climate Change Is Already Killing Polar Bears. Maybe Not.

2 months agoNews : Reason

Some "science-affirmers" of man-made climate change argue that melting Arctic Ocean sea ice will doom polar bears. Why? Because the bears hunt seals on he ice. No ice, no seals to munch on. It is true that the extent of summer Arctic...Show More Summary

Arctic Warming: Scientists Identify New Driver

A mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice has been identified by scientists. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.

Berkeley Lab scientists ID new driver behind Arctic warming

Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice. The research was led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). Show More Summary

Claim: Berkeley Lab scientists identify a new driver behind Arctic warming

From: DOE/Lawrence Berkeley National Laboratory Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice. The research was led by scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). They studied a long-wavelength region of the electromagnetic…

Arctic ice melt could pause in coming decades

Despite the rapid retreat of Arctic sea ice in recent years, the ice may temporarily stabilize or somewhat expand at times over the next few decades, new research indicates....

Arctic Warm – Continents Cold

The anomalously cold weather is part of a new climate pattern: Arctic Warm – Continents Cold The emerging explanation in a nutshell: because of less Arctic sea ice, there is more heat exchange between ocean and atmosphere, this is altering planetary-scale circulation patterns in ways that the cold air normally ‘bottled up’ in the Arctic is [...]

Arctic Melting Sends Winter Warning to Europe and Asia

2 months agoNews : Truthdig

By Tim Radford, Climate News Network Patterns of winds and pressure systems traced by researchers to the decline in Arctic sea ice can transport cold air further south and create harsher winters in Eurasia.

Cold winters tied to drop in Arctic sea ice

But only in Asia. And by the end of the century, it will all be over.
