Extreme wet years are getting wetter and more common. This means Australia's terrestrial ecosystems will play a larger role in the global carbon cycle.
Phasing out greenhouse gas emissions entirely by mid-century is possible, and promising trends are emerging. But the next five to ten years will be the real test of whether we can make that happen.
Without understanding why the 'fingerprint' has failed to appear our predictions about global warming - as carbon dioxide concentrations increase - are uncertain.
Carbon standards for cars are the cheapest way to cut emissions, and will save drivers money.
Victoria has announced a renewable energy target of 40% by 2025.
Despite advances in technology, carbon capture and storage could be unsettled by renewable upstarts.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.
The level of carbon dioxide in the atmosphere is rising faster than at any point in the past 55 million years.
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn't know how much of that was due to us, until now.
Working out how Mars's carbon dioxide was turned into rock could help with carbon capture efforts on our own planet.
Carbon dioxide is rising faster than any time in the past 66 million years. Rapid rises in the past have been linked to mass extinctions.
Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
February 2016 was the hottest month by the biggest margin ever. Does that mean global warming has gone into hyperdrive?
Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
Methane is a stronger greenhouse gas than carbon dioxide, and Australia's coal mines are a major source.
Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
Even before the death of Justice Antonin Scalia, the Supreme Court’s stay placed the fate of the EPA Clean Power Plan into the hands of the next president.
