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.
Sixty per cent of the heat created by gas ranges ends up heating you and your kitchen, not the food; with an induction range, only 14 per cent of the heat is lost.
A detailed study has shown that emissions from the food system alone will drive the world past the global heating target unless high-methane foods are tackled.
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.
The doors of a metal box slide open, and a drone rises over a gas well in Pennsylvania. Its mission: To find leaks of methane, a potent greenhouse gas, so that energy companies can plug the leaks and reduce the emissions that pollute the air.
