A ruling by the Saskatchewan Court of Appeal recognizes the threat of climate change, but its approach is too narrow.
Greenhouse gas emissions from plastic production in the vinyl era is not a patch on the equivalent from running giant servers today.
Carbon taxes on fossil fuels such as gasoline help lower greenhouse gas emissions.
Environmental taxes encourage consumers to conserve energy or switch to less carbon-intensive fuels.
The exploitation of fossil fuels emits CO₂, the main cause of global warming.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
Unconventional gas wells are being approved in their thousands across Australia.

Gas mining is expanding across Australia, and has been touted as part of the answer to cutting emissions. But there is evidence that this rollout will pose significant health and environmental risks.
The Chickamauga Dam, completed in 1940, was a crowning achievement of the New Deal.
The original New Deal caused a "great acceleration" in carbon emissions. How will a Green New Deal forge its own legacy?

The Green New Deal has shifted the debate over what to do about climate change.
While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.
The solar boom continues, but not necessarily because of government policy settings.
Australia's government insists it is on track to surpass its emissions reduction commitments under the Paris Agreement. But while that may be true, it will only happen with some clever accounting.
Across our growing cities more and more buildings are going up, as are their emissions.
Australia's commitments to cut emissions are on a collision course with urban growth. We need a much more comprehensive strategy to make the transition to a sustainable built environment.
Fire danger conditions are worsening in many areas of Australia.

Australia is facing an increase in extreme heat, fire danger weather, floods and marine heatwaves, according to the latest biennial snapshot from the Bureau of Meteorology and CSIRO.

Three years after the Paris Agreement, negotiators have finally agreed (most of) the rules for its implementation. But there is still no way to compel countries to deepen their climate ambitions.
Delicious, nutritious… and emissions-intensive.
Most consumers underestimate the greenhouse emissions associated with different foods. But environmental labels, similar to existing nutrition information, can help us make lower-impact choices.
The lack of political will to meet emission targets could see more extreme flooding in the future, like what happened the Québec community of Gatineau in 2017.

Achieving climate objectives is economically realistic, but won't be possible without the support of a real transition strategy that is still lacking at all levels of government in Canada.
Economists have searched for the mythical balance between the cost of climate action, and the future cost of doing nothing.
For decades, economists have pondered the 'social cost of carbon' - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.
Paris is burning.
The gilets jaunes protests show we need to fight inequality for a just transition to a low-carbon society.
A better tomorrow?
Brexit may be an unexpected boon for the UK's climate leadership. Here's how the UK can seize the initiative.

Hundreds of US cities have pledged to meet the carbon reduction targets in the Paris climate accord. Now it's time for them to start showing results.
