Here are the essential facts from the UN's special report on climate change.
The IPCC’s first cities conference revealed the challenges in bridging the gaps between scientific knowledge and policy practice, and between cities in developed and developing nations.
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.

Don’t dismiss what science has to say about the fate of coral reefs.
Marine scientists have been accused of being biased towards 'doom and gloom'. But it's not bias if the outlook for coral reefs really is gloomy.
It’s a tall order - especially when it’s spelled out on the Eiffel Tower.
How will the world actually deliver on the Paris climate ambition to hold global warming to no more than 1.5℃? It's a tough scientific and technical challenge.

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?
There are three things the new head of the IPCC can do now to help people understand climate science.
Can negotiators in Paris get a hit?
The UN climate talks in Bonn last week left many key issues unresolved, creating big challenges for forging a global deal in Paris later this year that would avert the worst effects of climate change.
Bonn in June: just a few steps away from the big show in Paris later this year.
It's pledge season: countries are beginning to submit carbon reduction commitments for the Paris climate talks later this year. What's the US doing and can it meet its targets?
The Netherlands has long embraced renewable energy, but some judges say it must do more.
The IPCC's UN-validated climate science could be used to hold governments to account.
It takes time, but this is how a real consensus is built.

There is a way for governments to find out the consensus on global issues such as climate change. But it involves painstaking, complex work, and an end to the adversarial clash of competing ideologies.
The United Nation’s IPCC is considered the definitive source on climate science in international negotiations.
At a crossroads with its chairman leaving, the UN’s IPCC looks to engage more social scientists and representatives from developing countries.
