Greenland Ice Sheet Melting Faster than Ever

More data show that ‘Yes, climate change is happening, ice is melting at alarming rates, and the time for action is now.’

Independent research using state-of-the-art modeling and satellite observations shows that melting of the Greenland ice sheet is speeding up.

Four months ago, new research showed that Arctic sea ice was at its lowest point in about 800 years, another study a couple months ago showed suprisingly fast melting in Greenland and Antarctica. Now, research from other scientists in Bristol (UK) published in Science confirms that ice sheets in Greenland are melting at an unprecedented rate.

There has been a lot of effort in the past few months to knock down climate change activists, say it isn’t happening. No wonder, of course, given that we are quickly approaching one of the most important meetings in the history of the human race — the climate change conference in Copenhagen. This new report shows again that whether we admit it or not, ice is melting, sea levels are bound to rise, climate change is happening, and the whole world will be changed as a result of it.

2000-Year Arctic Cooling Trend Reversed Itself Near Turn of 20th Century

According to the NAU researchers, the warming that occurred in the 20th Century and early 21st Century, “contrasts sharply” with the millennial-scale cooling trend; the last half-century being the warmest in the record, and, the decade from 1999 - 2008 being the warmest decade of the last 200 decades. Over all average temperatures were 1.4° C (about 2.5° F) warmer than the projected value based on the linear cooling trend.

Arctic Seal Threatened By Global Warming Denied Protection By Obama Administration

Spotted seal for article about Endangered Species protections denied by Obama administration

The spotted seal, a sea ice-dependent Arctic species, has been denied Endangered Species Act protection by the Obama Administration.

Disappointment: The Center for Biological Diversity has announced that the Obama administration denied Endangered Species Act protection for the spotted seal, a species whose habitat is rapidly melting away due to global warming.

Lasers from Space Show Ice Sheets Thinning — Greenland and Antarctica

This week in the journal Nature scientists give the most comprehensive view of thinning ice sheets in Greenland and Antarctica to date.

Scientists from British Antarctic Survey (BAS) and the University of Bristol analyzed 50 million satellite measurements (from NASA) to show the massive ice loss on these polar giants.

The result are surprising, even to the scientists.

Pacific Walrus Threatened by Global Warming, Oil Development: Feds Considering ESA Protections

Finally, the U.S. Fish and Wildlife Service is reviewing the status of the Pacific walrus to determine whether or not the marine mammal will receive Endangered Species Act protections.

The Center for Biological Diversity stated that the Pacific walrus (Odobenus rosmarus divergens) is facing a double threat to its ice habitat: Global warming and increased oil development.

A petition seeking protection for the Pacific walrus was submitted by the Center back in February 2008. After the USFWS failed to respond to the petition, the Center filed a lawsuit - prompting the USFWS to take action.

Global Warming in the Arctic — Much Worse than We Thought!


A new study by the World Wildlife Fund (WWF), released today, says that the effects of warming in the Arctic are “dire… far worse than previous projections.” Dr Martin Sommerkorn, senior climate change advisor for WWF’s Arctic program (who works on this stuff everyday) says: “What they found was a truly sobering picture.”

Russia’s Northeast Passage Open to Commercial Shipping

Commercial ships set out for the first time to navigate the open waters of Russia’s Northeast Passage.

Deep Down into the Antarctic Ice

It’s early Sunday morning at Halley Research Station, Antarctica. The sun is rising quickly on the horizon, the wind is low and the temperature outside is a modest -18 degrees C. Conditions look perfect. As I look across the dining room at my friends and colleagues Niv and Colin I see two smiling faces nodding back at me. Today we are going to head out to the coast and attempt to explore a large crevasse at a point on the Ice shelf known as Creek Five.

It is the British Antarctic Surveys most southerly and remote research station. I am lucky enough to be a member of the eleven strong wintering team working as the chef on Station. With the impending arrival of 24 hour darkness we are all keen to make the most of the remaining daylight, taking every opportunity to make the most of our time in this amazing place.

Dancing Skies over Antarctica

During the winter months on the Antarctic continent not only do we experience 24 hour darkness but we are privileged to see the aurora australis.  Here at Halley Station we were looking forward to experiencing many a night gazing at the dancing lights as they flitter across the sky.   Reading the small print however, revealed that there is a cycle of activity that revolves around an 11 year period.  It seems that 2009 is a low solar activity year and hence our expectations might have been a bit high.

FryckowskaLarge flares or solar explosions from the sun will expel numerous amounts of solar particles which make their way towards Earth.  These particles come into contact with the Earth’s magnetosphere and are directed towards the polar regions.  High energy particles then cascade into the highest parts of the Earth’s atmosphere, ionising gases.  It’s this process that emits the glows that we see on Earth.  The variation of colour is a result of particles with different energies ionising different gases.

Love Connection for Cute Knut: Polar Bear May Just Get the Girl!

Finally - some great news for cute Knut, the famous two-year-old polar bear that captured the hearts of many!   The white-as-snow bear is getting the chance to make a very special love connection with a two-year-old stunner named Gianna. 

Making Energy from a Nuisance Surplus Fish

The Greenland shark is just a nuisance to fishermen. It is toxic for humans to eat. It gets caught in our nets.

Thousands are thrown back into the sea each year.

“It’s a large predator that devours fish, squid, seals and other marine life, and it also ruins the lines and nets of the halibut fishermen,” says Leif Fontaine, the head of Greenland’s fishing and hunting association.

“Entire trawlers are sometimes full of sharks and they are caught everywhere, especially off the east and west of Greenland, to the fishermen’s great dismay,” says Bo Lings who used to work on a big trawler.”

In Uummannaq, Greenland sharks represent more than half of the waste disposed of by the local fishermen.

They can weigh a ton and be 23 feet long.

So, why not get some use out of them?
