Analysis of the phenomenon of "total circulation" -- situations in which humanity produces a circulation of goods or persons that escapes its control.
The current rise in atmospheric carbon dioxide levels is unprecedented in the past 800,000 years. As our video explains, ice cores track human changes to the atmosphere that are far beyond natural.
The Finkel review is designed to create a coherent and realistic plan for a low-emissions future. Here are the details you need to know.
While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.
Some experts say it's better for the US to leave the Paris Agreement than white-ant it from within. But that ignores the damage that a US withdrawal would do to the fabric of global multilateralism.
Keeping things cold wastes a massive amount of energy. What if this could be harnessed?
Even supposedly "green" technologies such as renewable energy require materials, land and solar exposure and cannot grow indefinitely on this planet.
University research has shown us how urgently we need to reduce greenhouse emissions. Yet only three Australian universities have followed through by committing unequivocally to cutting carbon.
Global emissions from fossil fuels have stalled. That puts us in the right place to keep warming below 2℃, but there's plenty of work still to be done.
Leaders are worried US leadership on global issues like climate change will be diminished under President Trump. Experts explain why China is ready to lead, and how that could be a good thing.
The idea of clean coal has been around for 40 years, but remains a pipe dream.
Australia's plan to bring fuel efficiency standards up to par with the US and Europe could see us say goodbye to regular unleaded, and hello to a useful way of cutting our rising greenhouse emissions.
The end of 2016 has brought balmy Arctic temperatures and record low ice extent for the time of year. It's a freak event even by modern standards, and climate models point the finger firmly at humans.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
The Earth's orbit has driven ice ages in the past but those days could be over.
The food we eat is responsible for almost a third of our global carbon footprint.
Cape Grim's air pollution station has recorded some of the biggest changes to the world's atmosphere over the past 40 years.
Poor management of the oceans, including the killing of crucial marine predators, could result in more greenhouse gasses.
While action on air pollution is welcome, there may be better ways to cut car emissions.
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?
