A new study, still tentative, suggests that climate change will have much worse effects on global food production and supply than experts have previously estimated.

"LONDON -- The cause of much of the recent extreme weather across the world is climate change triggered by human activities, scientists say. The paper suggests that man-made climate change is repeatedly disturbing the patterns of airflow around the northern hemisphere."

"Earth's increasingly hot, wet climate has cut the amount of work people can do in the worst heat by about 10 percent in the past six decades, and that loss in labor capacity could double by mid-century, U.S. government scientists reported on Sunday."

"None of Japan’s 16 nuclear power plants has satisfied the government's proposed new safety standards, making them ineligible to be restarted in the near future, according to an Asahi Shimbun survey."

"Wildfires in Alaska have become more widespread over the past 50 years, according to scientists in the US. The result suggests that Arctic wildfires will have an important effect on the climate in years to come – although whether it will be positive or negative, the researchers cannot say."

"Super mega dolphin pod, which indulged in a feeding frenzy off the coast of San Diego over the holiday weekend, is only the latest in a recent string of odd behaviors by large creatures of the sea."

"Sea Shepherd is claiming victory after Japan temporarily suspended its annual whale hunt in the Southern Ocean."

"A patient infected with a new respiratory illness similar to the deadly Sars virus has died in the UK."

"SOUTHERN OCEAN -- The Japanese whaling factory ship Nisshin Maru has collided with two whale conservation vessels and its own refueling tanker in Australia’s Antarctic waters, damaging the other ships. No injuries are reported."

Two new scientific studies explain a paradox: climate change is likely to bring more blizzards but less snow overall. It's physics.
