World’s climate scientists to issue stark warning over global heating threat

IPCC's landmark report will be most comprehensive assessment yet as governments prepare for pivotal UN talks in November

The fires, floods and extreme weather seen around the world in recent months are just a foretaste of what can be expected if global heating takes hold, scientists say, as the world's leading authority on climate change prepares to warn of an imminent and dire risk to the global climate system.

The Intergovernmental Panel on Climate Change (IPCC) will on Monday publish a landmark report, the most comprehensive assessment yet, less than three months before vital UN talks that will determine the future course of life on Earth.
