Let's put this to bed, shall we?
Scientists are more certain than they have ever been that humans are causing climate change and believe that sea levels could rise by up to 2ft 8in by the end of the century.
These are among the key findings likely to be published next month in the most authoritative and comprehensive report ever conducted into climate science - the UN Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment, known as AR5.
According to a draft of the report, the certainty that humans are the main cause of climate change has risen to 95 per cent, from 90 per cent in the previous - fourth - assessment six years ago. This, in turn, was a significant increase on the 66 per cent certainty reached in 2001’s third assessment and just over 50 per cent in 1995.
With every IPCC report there is a key phrase that encapsulates the latest consensus on climate change, which scientists wrangle over for months.
According to a leaked copy of the draft, the key phrase in the forthcoming report will say: “It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010.”
“There is high confidence that this has warmed the ocean, melted snow and ice, raised global mean sea level and changed some climate extremes,” adds the draft, which could be changed before the final version is published in Stockholm in September.
The draft projects that seas will rise by between 29cm and 82cm (11.4 to 32.3 inches) by the end of the century, while greenhouse gas emissions continue to soar.
The latest in a series that began in 1990 and last reported in 2007, AR5 has 840 main authors recruited from 38 of the IPCC’s 195 member countries, with British and American scientists making the biggest contribution.
