Climate scientists have set out how we could limit global warming, but their scenarios are not at all realistic.
The kind of climate action outlined by the ubiquitous climate checklists won't be enough.
The UN's panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5 degrees Celsius. But these techniques are largely unproven.
Limiting human-induced warming will be tough, given where we start from.
Limiting global warming to 1.5C is a tough challenge but still within reach, according to a landmark report from the Intergovernmental Panel on Climate Change commissioned after the 2015 Paris summit.
The world needs to be carbon-neutral by mid-century to give ourselves a chance of holding global warming to 1.5C. With around 1% of the global carbon budget, Australia needs to rapidly do its share.
Here are the essential facts from the UN's special report on climate change.
The first IPCC conference on cities has highlighted the challenges of reconciling science, urban practices and politics. But it was an important recognition of cities' leading role in climate action.
Climate change imperils food supply in many parts of the world, including South Africa, which has shown major gains in treating HIV/AIDS. Climate change could mean even less food -- and more disease.
