Canadian financial institutions are fuelling the climate change crisis

Canadian financial institutions — banks, pension funds and private equity firms — fund the fossil fuel industry and are therefore helping fuel the climate crisis. Why won’t Ottawa hold them to account?

As we fight the Alberta and B.C. wildfires, we must also plan for future disasters

High-risk, high-uncertainty events like earthquakes tend to fall out of view when we are occupied with more predictable seasonal events like wildfires, which have very visible effects on our lives.
In North America, log driving is thought to have stopped by the end of the 20th century, with the exception of British Columbia, where it is still practised on a small scale. (Shutterstock)

What log driving can teach us about forests, past and present

Logging over the past two centuries has had a major impact on Québec’s forests. The traces it has left will guide the adoption of sustainable forest management techniques.
‘The Sad and Cheerful Story of a Certain Dandelion’ was a theatre project in Poland that saw students create a script encouraging audiences to protect the local species. (Shutterstock)

Arts activities can provoke empathy and inspire youth action on urgent UN global goals

For young people seeking to engage with the world’s most critical challenges, the UN Sustainable Development Goals can serve as an entry point. The arts open up possibilities to take action.
The Hudson Bay Lowlands is among the fastest warming regions on the planet, with temperature increases projected to be up to three times higher than the global average. (Vito Lam)

How climate change is impacting the Hudson Bay Lowlands — Canada’s largest wetland

The impacts of climate change on the terrestrial ecosystems, that comprise interconnected webs of snow, water, plants and animals, can be rapid, complex, and unpredictable.

Forest fires: North America’s boreal forests are burning a lot, but less than 150 years ago

North America’s boreal forests have been burning a lot, probably more and more over the past 60 years. Yet the long-term trend indicates that they are burning less than they were 150 years ago.

As Alberta’s oilsands continue leaking toxic wastewater, aquatic wildlife face new risks

As toxic water continues to spill from tailings ponds across mining developments, decades of scientific research provides evidence of how wildlife will be affected.
Trees are rooted to the ground — but they move into new areas as the wind carries their seeds or seedlings are planted. (Shutterstock)

How to move without legs or wings: Helping trees migrate to new regions

The rapidly changing climate presents many challenges for the sustainability of forest ecosystems. Assisting the migration of trees is a tool to address these challenges.

How schools and families can take climate action by learning about food systems

Both at home and in schools, food can become a powerful tool to empower young people to take climate action, which can lead to reduced climate anxiety and increased feelings of hope for the future.

Local food is not enough — we need a sustainable transition in the food system

In light of the changes caused by the pandemic, it is clear that food autonomy as a frame of reference for reorganizing the Québec food system is not enough.
Smouldering fire in a drained peatland near Fort McMurray, Alta. produces smoke from underground. These ecosystems are affected by rising temperatures, drought, wildfire and various human actions including drainage. (Leyland Cecco)

Up in smoke: Human activities are fuelling wildfires that burn essential carbon-sequestering peatlands

New research shows that northern peatlands may not help regulate our climate by the end of the century.

Studying the stomach contents of spiders shows how they help control crop pests

Spiders liquefy their prey in order to consume it, and this makes it challenging to determine what spiders eat. A new approach that uses DNA barcoding is helping researchers figure out spider diets.

How a Supreme Court case could decide the future of Canadian climate policy

Canada’s federal Impact Assessment Act seeks to minimize the environmental impacts of major economic projects. Will the Supreme Court uphold the act?
