Warmer Arctic spells colder winters. 'Unicorn' whales do scientists favor by taking Arctic temp
It's no secret that the proverbial canary in the climate change mine is the Arctic. As National Oceanic and Atmospheric Administration (NOAA) administrator Jane Lubchenco noted when her organization launched its annual Arctic Report Card last week,“To quote one of my NOAA colleagues, ‘whatever is going to happen in the rest of the world happens first, and to the greatest extent, in the Arctic.’”

But, even as the Arctic warms, seemingly irrevocably, it is still a formidable environment in which to operate, particularly in the winter. The coasts of Greenland, in particular, act as pathways for ice from the Arctic Ocean, as a result of which winter research expeditions can require icebreaking vessels that cost millions of dollars to charter.

Consequently, in some areas, such as Baffin Bay, a large area between northeast Canada and southwest Greenland, winter data have been scarce -- or, in the words of Mike Steele of the University of Washington, "there was this gigantic, embarrassing hole."

Narwhal_satellite That hole is now being filled - thanks to narwhals, medium-size whales, endemic to the Arctic, known as unicorns of the seas because of the single, spiralling tusk found in males.  read more »

Fearless journey to awaken conscience, to unite efforts, to rescue our planet. Lewis, with warmest heart we wish you success!

"This is not just about protecting a pristine environment," Pugh says, "it's about saving ourselves." Lewis’s Pick n Pay/SAP Everest Challenge on May 22 is all about spreading awareness of climate change and its effects. He will become the first person to attempt to swim 1km across an almost-frozen lake two-thirds of the way up Mount Everest, next to the Khumbu Glacier – at the breathtaking altitude of 5,300 metres.

Pugh once said “it’s a tragedy that it’s possible to swim at the North Pole.” He put himself through intense physical strain to raise awareness about climate change; he’s an ardent environmentalist who wants the world to know about the decrease in ice in the Arctic.  read more »

Flood waters engulf the cars and offices of Village Collision and Automed Auto Sales on Aster Road in West Warwick, Rhode Island on April 1, 2010. The state received record rainfall earlier in the week causing flooding in many areas.

You’ll need your boat inside the mall, too.

The Rhode Island Mall in Warwick was flooded Wednesday by 2 to 3 feet of water. The mall's owner told the Providence Journal that the building, which houses about 70 stores, has never flooded in 40 years, and the retailers had very little time to protect the merchandise.

The Pawtuxet River spilled over its banks. A state of emergency was declared in Warwick, residents in Cranston are being evacuated, schools are canceled, and people were told not to flush their toilets.

A new global study of Earth’s oceans shows a rapid rise in the number of “dead zones” - areas of seafloor with too little oxygen to sustain most marine life. The oxygen-starved waters have proliferated since the 1960s and now rank as one of the world's most pressing environmental problems.

Clocking in at over 8000 square miles (21,000 km2) this year, probably the largest dead zone today stems from the Mississippi River delta in the Gulf of Mexico. This is a site at the confluence of significant farming in the midwest and significant fishing (and shrimping) in the Gulf area. The dead zone spans east to west along the Louisiana and Texas coasts.

Several visible sites with expanding dead zones. Mississippi Delta at the top, with Yangtze River in the bottom left and Pearl River in the bottom right. The dead zones are the tinted clouds swirling at the coastal edge.

Threatened. L: the red squirrel will be lost within the next 20-30 years unless effective action is taken. This poor fella's just heard the news. R: the pine marten. One of England’s rarest, & cutest, mammals.

A pair of giraffes nuzzle as they stand in the bush near Koure, Niger. The IUCN lists west African giraffes as an endangered species.

A giraffe from Africa's most endangered giraffe subspecies. Their numbers have quadrupled to 200 since 1996, an unlikely boon experts credit to the impoverished government keen for revenue that has enacted laws to protect them, a conservation program that encourages people to support them, and a rare harmony with humans who have accepted their presence.

Climate change is robbing polar bears of their habitats, & is the greatest threat to their survival.

Polar bear products are used for furs, rugs and taxidermy. Melting sea ice in Arctic will kill thousands of bears in coming years; US says commercial trade must not be allowed to make the situation worse.  read more »

Researchers believe the Arctic Ocean seabed is thawing in patches and releasing greenhouse gases. Methane, trapped in the permafrost, 25 times more powerful than carbon dioxide, is bubbling out of the frozen arctic faster than expected.

Researchers ignite a bubble of methane on Alaska’s Steward Peninsula.

Methane is leaking from the East Siberian Arctic Shelf into the atmosphere at an alarming rate. The amount leaking from this locale is comparable to all methane from rest of the world's oceans put together. Methane is a greenhouse gas more than 30 times more potent than carbon dioxide.
