New federal research suggests greenhouse gas emissions from the Alberta oilsands may be significantly underestimated, adding to a growing pile of studies that say our understanding of what is going into the atmosphere is incomplete.

Greenhouse gas emissions from the way humans produce and consume food could add nearly 1 degree of warming to the Earth’s climate by 2100, according to a new study.

About one million square kilometres of Quebec is covered by boreal forest, roughly 70 per cent of the entire province. In the north, where ecosystems are less likely to have been altered by human activity, those forests have been accumulating and sequestering immense quantities of carbon for centuries.
