Climate inequality must take centre stage at COP29

Centring climate justice in our global efforts against climate change could bring myriad benefits for us all. COP29 in Baku must make this dream a reality.

Recent Ontario appeal court ruling on youth‑led climate case could be a constitutional ‘game‑changer’

A landmark legal ruling in Ontario could pave the way for greater government climate accountability in the province while setting an important precedent for the rest of the country.

New insights from Shakespeare’s England reveal striking parallels to contemporary climate change

New research on the European Little Ice Age in England has upended established narratives and provided a window into an era of climatic instability not too different from our own.

Want to build healthier cities? Make room for bird and tree diversity

Tree and bird diversity has been linked to a number of positive mental health outcomes. It is time that urban planners interested in human well-being take biodiversity into account.
The Arctic is warming nearly four times faster than the global average. Assessing the ecological impacts on this region requires long-term study and persistence. (James Schaefer)

The Canadian Arctic shows how understanding the effects of climate change requires long‑term vision

The key to understanding shifts in climate and life on Earth is sustained long-term research. Enabling this research to take place should be a priority for universities and governments.

New survey of IPCC authors reveals doubt, and hope, that world will achieve climate targets

‘Climate scientists’ are often understood as being a block of experts with monolithic beliefs. A new survey sheds considerable nuance onto the beliefs and perceptions of climate scientists.

How the ‘social cost of carbon’ measurement can hide economic inequalities and mask climate suffering

While poorer nations face more severe climate impacts, their ‘social cost of carbon’ remains disproportionately low, reflecting deeper economic inequities that complicate global climate action.

Is sustainable development possible? Only if we take a unified approach

Purely technical solutions to the challenges of sustainable development will likely end in failure. Living within planetary boundaries will require a unified effort across disciplines and economies.

How Hurricane Helene became a deadly disaster across six states

Helene’s size and speed worsened everything from its storm surge to its extreme flooding in the mountains. And another hurricane was coming right on Helene’s heels.
Canadian federal climate policies and investments look increasingly fragile. Could ‘carbon contracts for difference’ help ensure the survival of long-term climate action in Canada? (Shutterstock)

‘Carbon contracts for difference’ are not a silver bullet for climate action

Utilizing carbon contracts for difference mechanisms could help the federal government maintain its climate policies. But overly relying on these tools brings its own risks.

How climate change is undermining Indigenous knowledge and livelihoods in Central America

Recent wildfires in Belize shows how we must work together to revitalize Indigenous knowledge systems and plant the seeds of collaborative climate action.
Not all introduced species are a problem. The introduced Siberian Elm is an example of an “invasive” species which adapts well to its new ecosystem, providing benefits at the same time. (Shutterstock)

Climate change means we may have to learn to live with invasive species

Invasive species are not always harmful; some can even provide key benefits to native habitats in an era of climate change. Canadian conservation efforts should embrace the movement of species.
