WASHINGTON (Reuters) – Polar bear cubs forced to swim long distances with their mothers as their icy Arctic habitat melts appear to have a higher mortality rate than cubs that didn’t have to swim as far, a new study reports.
Polar bears hunt, feed and give birth on ice or on land, and are not naturally aquatic creatures. Previous reports have noted individual animals swimming hundreds of miles (kilometers) to reach ice platforms or land, but this is one of the first to show these swims pose a greater risk to polar bear young.

Anyone familiar with Harry Potter knows as least two things: 1) this is the U.S. opening weekend for the final movie in the blockbuster series about the boy wizard and 2) ultimate villain Voldemort uses horcruxes to hold bits of his soul and extend his life.
Leave it to U.S. Energy Secretary Steven Chu to riff on horcruxes to explain energy storage.
At issue is the decision by American Electric Power to put its plans for carbon capture and storage on hold, due to the weak economy and the lack of a U.S. plan to limit emissions of climate-warming carbon dioxide. Read the Reuters story about it here.
Some stories, no matter how serious, are just joke-prone. So it was this week with the proposed U.S. BULB act, which aimed to repeal light bulb efficiency standards that became law in 2007. Sponsored by Joe Barton, a Texas Republican congressman, the BULB bill failed to receive the two-thirds vote of those present in the House of Representatives that would have been needed to suspend House rules and pass the measure.
That was the signal for Washington politicians, interest groups and some headline writers to crank up the pun-producing machinery:
When munching on a sumptuous spread of white truffles, sampling almonds tucked into syrupy preserved figs or chomping on a cigar-sized chunky chocolate bar, do you ever wonder about these luxury foods’ environmental impact?
Apparently lots of consumers do — enough that organic, sustainable and otherwise “green” foods are proliferating at this year’s Fancy Food Show.
The long-running tourist slogan has a new meaning for all 40 of the shark species around the Caribbean island chain after the Bahamian government banned all commercial shark fishing in the approximately 243,244 square miles (630,000 square kilometers) of the country’s waters.
What’s good for sharks is good for the Bahamian economy. These big fish bring in about $78 million each year, or more than $800 million over the last 20 years, according to the Bahamas Diving Association — the Bahamas is one of the world’s premier shark-watching destinations for divers.
WASHINGTON (Reuters) – A U.S. federal judge upheld the status of polar bears as a species threatened by climate change, denying challenges by a safari club, two cattlemen’s organizations and the state of Alaska.
The ruling on Thursday by District Judge Emmet Sullivan confirmed a 2008 decision that polar bears need protection under the U.S. Endangered Species Act because their icy habitat is melting away.
No question about it: this has been a wild weather year so far in the United States, with record rains, droughts, wildfires and tornadoes. But a new study indicates that even routine weather events like rainstorms and cooler-than-normal days could pack a huge annual economic wallop.
Weather’s effect on all sectors of the U.S. economy may total $485 billion a year, as much as 3.4 percent of U.S. gross domestic product, according to research published in the current Bulletin of the American Meteorological Society. It is the first study to apply qualitative economic analysis to estimate the U.S. economy’s weather sensitivity.
Three weeks after he landed space shuttle Endeavour at the end of its final voyage, Captain Mark Kelly said he’ll be retiring from NASA and the U.S. Navy to be with his wife, U.S. Representative Gabrielle Giffords, as she recovers from gunshot wounds suffered in January.
“As life takes unexpected turns we frequently come to a crossroads,” Kelly wrote in a post on Facebook. “I am at this point today. Gabrielle is working hard every day on her mission of recovery. I want to be by her side. Stepping aside from my work in the Navy and at NASA will allow me to be with her and with my two daughters.”
