The Intergovernmental Panel on Climate Change (IPCC), made up of the world's leading climate scientists, set out the final part of its mammoth sixth assessment report on Monday.

The comprehensive review of human knowledge of the climate crisis took hundreds of scientists eight years to compile and runs to thousands of pages, but boiled down to one message: act now, or it will be too late.

The UN secretary general, António Guterres, said: "This report is a clarion call to massively fast-track climate efforts by every country and every sector and on every timeframe. Our world needs climate action on all fronts: everything, everywhere, all at once."
