On International Polar Bear Day, Hope for an Iconic Species

My first summer in the Arctic was 1991. I was working for the National Ocean Service, tracking migrating fish along the Beaufort Sea Coast. Our season didn't start until mid-July, as the ocean was still solid ice before then. In those...Show More Summary

Submarine data used to investigate turbulence beneath Arctic ice

Using recently released Royal Navy submarine data, researchers have investigated the nature of turbulence in the ocean beneath the Arctic sea-ice. Recent decreases in Arctic sea ice may have a big impact on the circulation, chemistry and biology of the Arctic Ocean, due to ice-free waters becoming more turbulent. Show More Summary

Google Street View has made it to Greenland, and it looks amazing

Google Street View has arrived to the northern island of Greenland, the massive piece of land in the Arctic Sea that is covered in ice for six months per year. As reported by VentureBeat, Google has put together a portfolio of images from its trip to the region. Show More Summary

Arctic Melting Opens Sea Route to More Pollution

2 weeks agoNews : Truthdig

By Alex Kirby, Climate News Network Increasing loss of Arctic sea ice is likely soon to mean more ships are able to use the polar passage—affecting climate, health and air quality.

Spinning Global Sea Ice

Patrick J. Michaels NASA takes the (frozen) cake with this one. It just released a report on global sea ice coverage that opens with the following sentence: Sea ice increases in Antarctica do not make up for the accelerated Arctic sea...Show More Summary

Global sea ice diminishing, despite Antarctic gains

Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new study finds. As a whole, the planet has been shedding sea ice at an average annual rate of 13,500 square miles (35,000 square kilometers) since 1979, the equivalent of losing an area of sea ice larger than the state of Maryland every year.

Sea Ice 101 – Insolated, Isolated, Insulated Icebergs in Space, A Mid-Term Exam

(Or, How Climate Science Is Taught Today) Guest essay by Robert A. Cook The following begins a series of topics on Arctic and Antarctic Sea Ice. And, since we (behind the keyboard) will be talking to you (the readers, and perhaps even the learners) as if we were openly addressing you in a classroom or…

NSIDC Mark Serreze’s sea ice ‘death spiral’ no longer ‘screaming’ on the way down, now termed to be ‘erratic & bumpy’

From the University of Colorado at Boulder, where they are apparently attempting to explain away why Arctic sea ice isn’t living up to previous wild claims such as those made by Dr. Mark Serreze of the National Snow and Ice Data Center, who famously said that the Arctic is in a ‘Death Spiral’ in response…

Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term

Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change -- and rapid change -- at the world's northern reaches, according to a new paper.

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

last monthHealth : 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

last monthUnited 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 months 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

2 months agoNews : 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.
