The increase in extremely hot summers predicted by climate change models will lead to a higher death toll that will not be offset by fewer deaths during warmer winters, say researchers. “The increase in mortality when you have one extra cold snap is 1.59%, but the increase in mortality for an additional heatwave is 5.74%,” explains Mercedes Medina-Ramón of Harvard University's School of Public Health.
Unless Canada puts a price tag on carbon emissions it risks “serious economic dislocation” in the form of sharply reduced economic growth. Given sufficient advance notice as to the financial incentives for cutting emissions, however, companies and consumers can make appropriate decisions.

A UN report has issued a desertification warning saying tens of millions of people could be driven from their homes, particularly in sub-Saharan Africa and Central Asia.
Without action, 50 million people could be displaced within 10 years.
A new study has found that many of Alaska’s roads, runways, railroads and water and sewer systems will wear out more quickly and cost more to fix because of climate change. From now to 2030, rising temperatures, melting permafrost, reduction of polar ice and increased flooding are expected to boost repair and replacement costs by 20 per cent to as much as $6.1 billion US.
China, India, Brazil and other emerging nations must be persuaded not to expect sustainable growth without taking environmental degradation into account, says an editorial in Asahi Shimbun. While developed nations such as the U.S. bear greater responsibility for fighting global warming, it is also necessary to pinpoint the “differentiated” role cited by the UN for developing countries.
