CBC News It is "crucial" the federal government does more to help Canadians cope with climate change, the federal environment commissioner says.
"Canadians are facing risks such as the spread of disease, more drought in the Prairies, melting permafrost in the North, longer and more intense heat waves and smog, and rising coastal waters," Johanne Gélinas said as she released a report Thursday criticizing Ottawa's efforts to combat climate change. |

AFP Thu Sep 28, 2006 WASHINGTON - A US doctors' group sued seven leading fast-food chains including McDonald's and Burger King over their use of a "dangerous carcinogenic" in grilled chicken.
ADVERTISEMENT The Washington-based Physicians Committee for Responsible Medicine (PCRM) filed suit in California "to compel the restaurants to warn unsuspecting consumers" through in-store posters and menu messages. The group said every sample of grilled chicken products from the seven national chains "tested positive for a dangerous carcinogenic compound called PhIP" during analysis at an independent laboratory. |

Reuters Thu Sep 28, 2006 ATLANTA - Travelers to parts of Africa and Asia are returning with a new mosquito-borne virus and the U.S. Centers for Disease Control and Prevention warned on Thursday it could become entrenched in new areas.
Some people returning to Europe, the United States, Canada, Martinique and French Guyana reported cases of Chikungunya fever (CHIKV) in 2006 and large outbreaks have been reported in Indian Ocean islands and in India, according to the report. |

Inter Press Service (IPS) Wed Sep 27, 2006 TORONTO - Boreal forests provide 250 billion dollars a year in ecosystem services like reducing atmospheric carbon and water filtration, but which have gone unacknowledged by governments and industry, experts say.
Governments need to begin accounting for those services before allowing timber, oil and gas and mining to carve up the world's remaining northern forests, argues the Edmonton, Canada-based ecological economist Mark Anielski. |

New Scientist "Further global warming of 1 °C defines a critical threshold. Beyond that we will likely see changes that make Earth a different planet than the one we know."
So says Jim Hansen, director of NASA's Goddard Institute for Space Studies in New York. Hansen and colleagues have analysed global temperature records and found that surface temperatures have been increasing by an average of 0.2 °C every decade for the past 30 years. Warming is greatest in the high latitudes of the northern hemisphere, particularly in the sub-Arctic boreal forests of Siberia and North America. Here the melting of ice and snow is exposing darker surfaces that absorb more sunlight and increase warming, creating a positive feedback. Earth is already as warm as at any time in the last 10,000 years, and is within 1 °C of being its hottest for a million years, says Hansen's team. "Large amounts of greenhouse gases are currently locked in the permafrost and if released could accelerate the greenhouse effect," says Balzter. Hansen's paper concludes that the effects of this positive feedback could be huge. "In past eras, the release of methane from melting permafrost and destabilised sediments on continental shelves has probably been responsible for some of the largest warmings in the Earth's history," he says.
