A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million hectares of trees along the northern edge of the boreal forest.

Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks.

For decades, scientists knew there was a huge swath of undetected and unaccounted for per- and polyfluoroalkyl substances (PFAS) in the atmosphere, often referred to as PFAS dark matter, but no one knew how much was missing or how to measure them.

In parts of the Arctic, polar bears are in decline as sea ice, which they depend on to hunt, disappears. That is not the case, however, on the Norwegian island of Svalbard, where bears have actually managed to grow more plump even as ice melts away.

To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020.

Trees play a central role in life on Earth. They store CO₂, provide habitats for animals, fungi, and insects, stabilize soils, regulate water cycles, and supply resources that humans rely on – from timber and food to recreation and shade on a hot day.

Agricultural waste that is usually burned or left to rot could play a far bigger role in tackling climate change if it were instead used in long-lasting building materials, according to new research from the University of East London (UEL).

Large-scale melting of the Greenland Ice Sheet is irreversible and happening at a rapid rate, and now a new international study is the first to understand why.

Solar panels on bodies of water in the northeastern U.S. might generate renewable energy but could also carry risks for birds, especially water birds.

In the time it takes to blink, octopus and cuttlefish can seemingly disappear into their underwater environment by changing both the color and texture of their skin.
