The former UN secretary-general reflects on the dinner parties and diplomacy that led to the Paris Agreement.

Scientists at the Commonwealth Scientific and Industrial Research Organization found it was theoretically possible to turn back the clock on the effect of decades of fossil fuel burning, but the radical step came with “as yet unquantified risks.”

“Overwintering” fires smoulder under the snow, reigniting vegetation in the spring. New research shows the zombies may proliferate in a warmer world.

That is the verdict of a new report from the Canadian Institute for Climate Choices, which found changing climate will worsen pre-existing health conditions and strain the health-care system unless governments take significant action.

Net-zero emissions — balancing emissions by absorbing equivalent amounts of CO2 from the atmosphere — is the defining approach of international climate efforts. But some scientists are arguing that this strategy simply allows the perpetuation of the status quo and is certain to fail.

The ouster of the three Exxon board members is another blow to fossil fuel companies facing growing pressure to refocus their businesses in light of a dangerously warming world.

To hear the International Energy Agency warning about the dangers of the climate crisis is a game-changer, writes Greenpeace Canada senior energy strategist Keith Stewart.

Nearly 59 million hectares of forest have regrown since 2000, showing that regeneration in some places is paying off.

Patricia Lane introduces us to Mitchell Dickau, who reckoned the best way to illustrate the impact of climate change for skate-loving Montrealers was to calculate how many days without ice rinks rising temperatures will mean.

A survey of 800 cities around the world also found almost 43 per cent do not even have plan to adapt to the impacts of global heating.

The Sustainable Finance Action Council, launched May 12, will draw upon “financial sector leaders” for help in transforming Canadian markets so that they properly measure, price and disclose the risks faced by businesses from the climate crisis.
