Thick wildfire smoke blankets the landscape near Water Valley, Alta., in May 2023. Evidence linking wildfire smoke with adverse health effects has been accumulating for years.

The notion that wildfire smoke is ‘natural,’ and therefore less harmful than other types of air pollution, is not supported by the evidence. Wildfire smoke has been linked to adverse health effects.
Public interest in climate change and global warming peaks after bushfires and lasts for months, research reveals. But Australians do not respond to storms and floods in the same way.

Exploring the often unseen, and poorly understood, nuances of diversity within coral reefs may prove essential for ensuring the long-term health of Earth’s oceans.
It’s not just ocean temperatures that determine whether we have El Niño or La Niña. Air circulation also plays a role, and it’s changing in unexpected ways.

Even ‘climate havens’ face a riskier future, and infrastructure often isn’t built to handle climate change. But there are steps cities can take to prepare.
Both major parties are promising major road projects this election. Meanwhile, the potential for passenger and freight rail to help meet the country’s climate goals seems stuck at the station.
