"Roughly every six years the IPCC lays out the latest climate science in layman's terms, so policy-makers around the world can understand – and base policies on – accurate information about mankind's effect on rising temperatures.
"The 2013 report consolidated the belief that we are the dominant cause of warming to 95 per cent certainty. It acknowledged that the rate of surface-temperature rise had slowed in the past 15 years – but suggested that heating continues unabated in the oceans, and made it clear that short-term variations do not reflect long-term trends.
"Sea levels are rising faster than previously projected. Ice is melting faster, too. It is 'very likely' that extreme weather events will soon strike more regularly. And what we are doing now, the IPCC stated, is 'irreversible on a multi-century to millennial timescale'.
