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.
If shipping and aviation don't rein in their emissions it could seriously jeopardise our goal of preventing more than 2℃ of warming.
The greenhouse gases that cause climate change will take centre stage at the upcoming Paris climate talks. What are they and what are their effects?
Cooperation between regulators and the car industry has led to a huge reduction in dangerous emissions – and we can expect further progress.
Conflicting evidence means it's tough to tell whether trees helping to clear the air, or if green is not as good as we thought.
Rising carbon dioxide levels are making plants grow faster, sucking up more water and reducing river flows in many agriculturally important areas of Australia, according to new research.
Sharks and other ocean predators help protect the ocean's carbon stores by keeping other wildlife in check.
The dust storm that turned Sydney red in 2009 triggered plankton blooms in the Tasman Sea, demonstrating how we might fertilise the ocean to take up more carbon dioxide.
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
No matter how much we reduce greenhouse gas emissions, it will not be enough to keep global warming below 2C. Does this mean we should give up? Not at all.
