Australia is pumping 6.5 times more carbon into the atmosphere than the land can absorb.
South Australia's electricity price shock in July showed that Australia hasn't worked out how to put large amounts of wind energy into the grid.
Victoria's brown coal Hazelwood station produces 5% of Australia's electricity, and 3% of the country's carbon emissions.
A swell of business action is continuing following the Paris climate agreement.
The world has lost 10% of its wilderness areas in the past 20 years and, with it, vast stores of carbon.
Environment and energy minister Josh Frydenberg said that eight out of Australia's 12 most emission intensive power stations closed in the last five years. Is that right?
New research has found that carbon intensive companies have lost focus on reducing emissions under Direct Action, when compared with the carbon tax.
A new report published by the Climate Institute says Australia could avoid lengthy heatwaves and help save the Great Barrier Reef by meeting the Paris Agreement's 1.5C global warming goal.
Australia's energy watchdog has warned that closing coal power stations could leave us vulnerable to supply problems. But not if we help take the pressure off the grid.
Victoria has announced a renewable energy target of 40% by 2025.
Feeding Melbourne generates over 900,000 tonnes of edible food waste every year, enough to feed more than 2 million people.
Companies could improve their profits 2-10% each year by saving energy, according to a world-first attempt to assess energy performance.
Labor's detailed climate policy is ambitious, but it remains to be seen if it will capture the voters.
Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Over the past year Australia's greenhouse gas emissions from electricity rose 2.7%.
Self-driving cars are way more energy efficient than your average vehicle – but that doesn't necessarily mean they'll reduce carbon emissions.
Energy companies are realising that, in light of the Paris climate deal, the economics are starting to line up in favour of climate action, not against it.
Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
Australia's greenhouse emissions are once again rising, after a decade of consistent declines. But the right policies are already in place to turn things around - they just need to be ramped up.
