EARTH: US Navy navigates a sea change in the Arctic
The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism.

Scientists Determined First-ever Census for Emperor Penguins
A new study using satellite mapping technology reveals there are twice as many emperor penguins in Antarctica than previously thought. (2012-04-16)

Scientists complete first-ever emperor penguin count from space
There are twice as many emperor penguins in Antarctica than was previously thought, according to a new study released today by an international team of researchers using high-resolution satellite mapping technology. (2012-04-16)

Long-term studies detect effects of disappearing snow and ice
Ecosystems are changing worldwide as a result of shrinking sea ice, snow, and glaciers, especially in high-latitude regions where water is frozen for at least a month each year-the cryosphere. (2012-04-06)

Confirming carbon's climate effects
Harvard scientists are helping to paint the fullest picture yet of how a handful of factors, particularly world-wide increases in atmospheric carbon dioxide, combined to end the last ice age approximately 20,000 to 10,000 years ago. (2012-04-05)

PCBs levels down in Norwegian polar bears
It's never been easy to be a polar bear. They may have to go months without eating. Their preferred food, seal, requires enormous luck and patience to catch. Add to that the melting of Arctic sea ice due to climate change, and the poisoning of the Arctic by toxic chemicals, and it's easy to see why polar bears worldwide are in trouble. (2012-03-30)

State of the planet
Time is running out to minimize the risk of setting in motion irreversible and long-term climate change and other dramatic changes to Earth's life support system, according to scientists speaking at the Planet Under Pressure conference, which began in London today. (2012-03-27)

Increase in Arctic shipping poses risk to marine mammals
A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region's marine mammals and the local communities that rely on them for food security and cultural identity, according to an Alaska Native groups and the Wildlife Conservation Society who convened at a recent workshop.

NASA's IceBridge 2012 Arctic campaign takes to the skies
Researchers and flight crew with NASA's Operation IceBridge, an airborne mission to study changes in polar ice, began another season of science activity with the start of the 2012 Arctic campaign on March 13. (2012-03-16)

NASA Finds Thickest Parts of Arctic Ice Cap Melting Faster
A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean's floating ice cap. (2012-03-01)
