"While Arctic ice is melting at a record pace, a team of NASA-led researchers say they can explain why Antarctic sea ice has been edging in the opposite direction. That paradox has puzzled scientists for years and given climate-change deniers fodder to dispute global warming."
"After plunking down more than $2.5 billion for drilling rights in U.S. Arctic waters, Royal Dutch Shell Plc, ConocoPhillips and other companies have quietly relinquished claims they once hoped would net the next big oil discovery."
"Two years ago, a pair of scientific studies documented that the glaciers of West Antarctica, which hold back over 3 meters (nearly 10 feet) of potential sea level rise, are melting and retreating from below. The cause? It appears that these glaciers, which are perched on the seafloor deep below the ocean surface, are being lapped at by flows of warm ocean currents."

"An estimated 150,000 Adelie penguins living in Antarctica have died after an iceberg the size of Rome became grounded near their colony, forcing them to trek 60km to the sea for food."
"The latest report on the health of the Arctic reveals melting ice, shifting habitats and changes that may one day be mirrored around the world."
"Polar bear populations are likely to fall by more than 30 percent by around mid-century as global warming thaws Arctic sea ice, experts said on Thursday in the most detailed review of the predators to date."
