The level of carbon dioxide in the atmosphere is rising faster than at any point in the past 55 million years.
Feeding Melbourne generates over 900,000 tonnes of edible food waste every year, enough to feed more than 2 million people.
The city of Phalodi has set a temperature record for India, hitting 51℃. Until now, India's smog problem has curbed extreme temperatures. But that could be about to change.
What gaps have the CSIRO cuts left in climate research?
Labor's shadow environment minister, Mark Butler, said Australia is now "pretty much the only major advanced economy where pollution levels are going up, not coming down." Is that right?
The dairy industry faces a number of welfare issues, and is a major contributor to greenhouse gases.
To meet global climate change targets, agriculture needs an array of innovations and money to get farmers around the world to adopt new practices.
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.
Careful design can make sure we don't see another failed clean development mechanism.
Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Wildfire makes up about 4% of the greenhouse gases added to the atmosphere each year.
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.
The granting of a mining lease to the Carmichael coal project, despite the huge potential greenhouse emissions, shows that ministers need to consider the wider consequences of their approvals.
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.
Australia still rests too heavily on its luck, and not enough on its brains.
Eating meat means greenhouse emissions. But the emissions from growing crops may have been underestimated, meaning that a climate-friendly diet isn't as straightforward as simply going vegetarian.
Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
