It is the first such global assessment since 2013, when scientists found that global warming was “unequivocal” and human influence on the climate was clear, with the majority of warming since the 1950s extremely likely to be down to human activity.
The message in the latest report is expected to be even stronger, with warnings of how soon global temperatures could rise 1.5C above pre-industrial levels – a limit that countries have pledged to try to avoid breaching because of the dangerous consequences for humanity.
Drawing on more than 14,000 scientific papers, the review is set to provide the latest knowledge on past and potential future warming, how humans are changing the climate and how that is increasing extreme weather events and driving sea-level rises.
