Forest fire particles come to town

Researchers at the University of Toronto have detected migratory pollutants from a forest fire in Quebec and even particles from a sandstorm in the Sahara in Toronto air, findings that could someday give regulatory agencies an idea of who is contributing to the pollutants found in urban air.

“It’s a bit of detective work,” says Greg Evans, a professor in the Department of Chemical Engineering and Applied Chemistry. “We happened

French and Australian scientists resume measurements of Antarctic waters south of Australia this week to assess their capacity as a massive oceanic sponge to absorb greenhouse gases and store them away for hundreds or perhaps thousands of years.

France and Australia have a joint research program taking measurements from the Antarctic supply ship L’Astrolabe during its voyages between Hobart and the French base at Dumont D’Urville. L’Astrolabe, equipped with a full

Doing a little now to mitigate long-term climate change would cost much less than doing nothing and making an adjustment in the future, say scientists whose paper appears in the Oct. 15 issue of the journal Science.

Implementing a carbon tax of five cents per gallon of gasoline and gradually increasing the tax over the next 30 years is the optimal solution, the researchers report. “You can think of the tax as a low-cost insurance policy that protects against climate change,” sa

On Jan. 14, 2005, the Huygens probe will plow into the orange atmosphere of Saturn’s moon, Titan, becoming the first spacecraft to attempt to land on a moon in our solar system since the Soviet Union’s Luna 24 touched down on Earth’s moon in 1976.

Though scientists hope that Huygens will survive the plunge, it will be flying blind through hydrocarbon haze and methane clouds to a surface that could consist of seven-kilometer-high ice mountains and liquid methan

The proposed construction of a European Arctic Flagship ‘AURORA BOREALIS’, the 250 Million Euro joint European Research Icebreaker with a deep drilling capability would result in a considerable commitment of the participating nations to coordinate and expand their Polar Research Programmes. Recent results from drilling of the Deep Arctic Ocean within the Arctic Coring Expedition (Acex) have revealed dramatic changes of climate in the Arctic region during the last 55 million years. European science

Vilified in popular culture as a relentless man-eater, the great white shark finally received today global recognition as a persecuted species worthy of protection, as participants of the 13th meeting of the Convention on International Trade in Endangered Species of Flora and Fauna (CITES) adopted a proposal to improve management and monitoring of trade in jaws, teeth and fins from the world’s largest predatory fish. Led by the governments of Madagascar and Australia, the proposal to list the
