"Polar bears are capable of swimming vast distances, a potential survival skill needed in an Arctic environment where summer sea ice is vanishing, a study led by the U.S. Geological Survey showed on Tuesday."
"Despite investigations by four special committees, key questions remain about the crisis at the Fukushima No. 1 nuclear power plant, the world's worst nuclear disaster since Chernobyl."
"Some of the main proposals in a draft text for negotiation at a U.N. sustainable development conference next month are being watered down at informal talks in New York, observers said on Tuesday, heightening fears the summit will fail to deliver."
Early headlines in some "news" media about a study discussing the effect of wind turbines on local microclimates drastically misstated the findings and implications of the study, various debunkers point out.
"The cause célèbre of plastic litter in the ocean is the Texas-sized, swirling island of plastic debris thousands of miles off the coast of California in the Pacific Ocean. But researchers from the Universities of Washington and Delaware and the Sea Education Association in Woods Hole, Mass., say the story is much bigger, and scarier, than that."
"Pacific reef shark populations have plummeted by 90 percent or more over the past several decades, according to a new study by a team of American and Canadian researchers, and much of this decline stems from human fishing pressure.
Quantifying the decline for the first time, the analysis, published online Friday in the journal Conservation Biology, shows that shark populations fare worse the closer they are to people — even if the nearest population is an atoll with fewer than 100 residents.
"Killer health problems such as diarrhoea, malnutrition, malaria and dengue are highly sensitive to climate change and could worsen in the coming decades, health experts agree. But how, where and to what extent remains unclear."
"New research suggests that global warming is causing the cycle of evaporation and rainfall over the oceans to intensify more than scientists had expected, an ominous finding that may indicate a higher potential for extreme weather in coming decades."
Let the games begin. This summer's Olympics in London will include an epic contest in the public relations arena.
"CAMBRIDGE, UK -- Warm ocean currents flowing beneath ice shelves are the main cause of recent ice loss from Antarctica, concludes a study by an international research team published today. The finding brings scientists closer to providing reliable projections of future sea level rise."
