Installing green infrastructure in residential areas can prevent stormwater from flooding sewer systems and significantly curb heavy metal pollution, suggests a new study.

Montreal’s methane emissions are unevenly distributed across the island, with the highest concentrations in the city’s east end, McGill researchers have found. The worst polluters include the city’s largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks.

Sea ice coverage in the Arctic Ocean is at one of its lowest levels on record, yet there’s no unanimity on when that ice will disappear completely during summer months.

A global research effort led by Colorado State University shows that extreme, prolonged drought conditions in grasslands and shrublands would greatly limit the long-term health of crucial ecosystems that cover nearly half the planet.

An AWI study gives a potential explanation as to why the ocean around Antarctica is defying climate model projections and continuing to absorb CO2, despite the effects of climate change.

Human disturbance has a significant impact on the behaviour and habitat use of urban wildlife, however, in some situations urban grey squirrels may actually feel safer from predators where our activity is high.

The leaves have turned in the northern hemisphere and the Lower Mainland is seeing its blaze of glory.

When scientists want to trace how a species has changed over time — and predict its prospects for survival — they turn to DNA.

In the near future, Juneau’s Mendenhall Glacier will withdraw its icy toe from the lake of its making, scientists say.

A few miles north of Berlin, the Schönerlinde wastewater treatment plant hums with quiet urgency. Dark brown water flows through a series of concrete tanks, alive with microorganisms breaking down almost everything that’s flushed away in the northeastern parts of the nearby German capital.
