Schools in New Delhi were forced to close on Monday after heavy monsoon rains battered the Indian capital, with landslides and flash floods killing at least 15 people over the last three days. Farther north, the overflowing Beas River swept vehicles downstream as it flooded neighborhoods.

New research using real-world data casts doubt on the energy efficiency of diesel alternatives that come from phytoplankton.

A new groundbreaking analysis of safety and justice hopes to inform the next generation of sustainability policy.

A study suggests that rather than helping you go incognito, soapy fragrances could make you a more attractive target, with mosquitoes favouring the scent of volunteers who washed with three out of four popular soap brands tested.

Edgar (Eddie) Dearden skips the small talk when he meets someone new, instead starting the conversation by asking them if they "know what natural gas is." The question is the centrepiece of his self-appointed quest to fight the fossil fuel industry's insidious disinformation campaign painting natural gas as a climate solution. 

Environmental campaigners urged climate envoys from dozens of nations gathering in Berlin to discuss a global deadline for phasing out fossil fuels and ways of increasing aid to poor countries hit by global warming.

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.

Gray wolves, elephants, wildebeests and sea otters are a few of the species that can help keep global warming below 1.5 C.

The continued global rise in sales of SUVs pushed their climate-heating emissions to almost one billion tonnes of carbon dioxide in 2022, according to the International Energy Agency.

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.

Communities around the world emitted more carbon dioxide in 2022 than in any other year on records dating to 1900, a result of air travel rebounding from the pandemic and more cities turning to coal as a low-cost source of power.

The co-author of a recent study says its results have implications for anyone who has to think hard in polluted areas.

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.

Material from dry landscapes has surged since the 1800s, possibly helping to cool the planet for decades.

Canadians' food scraps and mouldy leftovers could soon find new life as bioplastics, solidified carbon — and even menstrual pads.
