Workers seen on top of the cliff at the Big Bar landslide on the Fraser River in July 2019. Fisheries and Oceans Canada officials said that 99 per cent of early Stuart sockeye and 89 per cent of early chinook salmon were lost that year. The fish couldn’t make it past the landslide.

“We just knew no fish would get by. Not without our help.” Behind the scenes of the epic campaign to save a Fraser River salmon run.

Vents and chimneys on an underwater volcano

Colourful hydrothermal vents and chimneys on the volcanic Vailulu'u seamount in the Samoan islands. The ocean floor was long thought to be flat and featureless, but new technology is revealing — and mapping — its diverse topography. (Photo: Vailulu'u 2005 Exploration, NOAA-OE)

This past summer an ambitious wildlife under/overpass system broke ground in B.C. on a deadly stretch of highway just west of the Alberta border. Here’s how it happened.
Three polar bears cast long shadows as they move across snowy Arctic scenery

Since the start of satellite records in 1979, the number of days per year that sea ice is present has declined in each subpopulation’s region. (Photo: Andreas Preußer, CC BY-ND 3.0)

Public health measures aimed at slowing the spread of COVID-19 have also reduced transmission of flu — but this is not the year to blow off your annual flu shot
Two men scale a steep cliff above a lake

Canadian Space Agency astronaut Joshua Kutryk and NASA Artemis astronaut Matthew Dominick hunt for rocks on a cliff above Kamestastin Lake in Labrador. The lake was created by a meteorite impact, and the area’s geology has many similarities to that of the moon. (Photo: Gordon Osinski)

Future missions to the moon will focus heavily on geology. Fortunately, Canada offers astronauts the perfect place to hone their skills.

Two leather sea stars photographed by marine ecologist Chris Harley in Vancouver’s Stanley Park on July 12, 2021, illustrate the impact of the extreme heat wave that hit Western Canada this past summer. The live star on the left was in a shady spot, while the star on the right perished in the direct sun. (Photos: Chris Harley)

As the impacts of global warming become increasingly evident, the connections to biodiversity loss are hard to ignore. Can this fall’s two key international climate conferences point us to a nature-positive future?
