Canada closing its marine pollution program

Canada has been sending letters to government scientists notifying them that their jobs will be eliminated or affected by the closure of the country's marine pollution program -- but at least one isn't going without making some noise. "It's perplexing that we face the loss of this program, given the 25,000 chemicals on the market and the ever-increasing threats posed by shipping and oil and gas exploration and development in temperate and Arctic waters," Peter Ross told Ross is perhaps Canada's best known marine scientist for his work on identifying killer whales as the most contaminated marine mammals on the planet. "As can be expected when one is told their position is being terminated, one is shocked and saddened," he added. "However, when told that the entire pollution research and monitoring program for Canada's oceans is being eliminated, I was speechless."

Navy raises sonar impact on dolphins, whales dramatically

New Navy estimates showing many more dolphins, whales and other marine mammals could be hurt by sonar off Hawaii and Southern California caused alarm among environmentalists on Friday. The Navy, for its part, emphasized those were worst-case estimates and that the numbers cover a much larger testing area than before.

Himalayan Ice melt less than thought

Estimates from satellite monitoring suggest the melt rate from the Himalayas and other high-altitude Asian mountains in recent years was much less than what scientists on the ground had estimated, but those monitoring the satellite data warn not to jump to the skeptical conclusion. The region's ice melt from 2003-2010 was estimated at 4 billion tons a year, far less than earlier estimates of around 50 billion tons, according to the study published Wednesday in the peer-reviewed journal Nature.
