Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale.

Canada’s drinking water can remain at risk long after wildfires burn out, according to a UBC-led global review that found water-quality impacts often emerge months or years later—not just immediately after a fire.

More than 350,000 chemicals are used worldwide, and many find their way into the ocean through plastic pollution.

Contamination of ground, surface and drinking water by perfluoroalkyl and polyfluoroalkyl substances (PFAS) affects millions of people worldwide.

Nations worldwide underestimate greenhouse gas emissions from wastewater systems, research from Princeton University shows. Outdated inventory methods and failure to include items like latrines and untreated sewage in national reports are main reasons.

In the future, regional flights such as Trondheim-Oslo could become much more environmentally friendly with the help of a hybrid aircraft engine.

It’s one of the latest technologies for sequestering carbon: Crush silicate rocks, add to crop soil, and let the rock dust naturally react with carbon dioxide.

A two year field experiment carried out in the world’s northernmost cultivated peatland, located in Pasvik in Finnmark, shows that greenhouse gas emissions can be greatly reduced by raising and maintaining the water table at 25–50 centimetres below the soil surface.

As Canada experiences record snowfall, new research from the University of Waterloo suggests that tiny amounts of industrial pollution trapped in snow can change how sunlight reaches the ground below and significantly alter fragile environments.

Geologic reservoirs that trapped petroleum for millions of years are now being repurposed to store the greenhouse gas carbon dioxide.
