The Intergovernmental Panel on Climate Change published the “synthesis report” of its sixth assessment report (AR6) on Monday. Eight years in preparation, this mammoth report encompasses the entire range of human knowledge of the climate system, compiled by hundreds of scientists from thousands of academic papers, and published in four parts, in August 2021, February and April 2022, and March 2023.
The report drew together the most important findings – but also highlighted some key measures that governments and countries must take immediately if we are to avoid climate catastrophe:
Reduce methane

Sharp cuts to short-lived climate pollutants, methane chief among them, could cut more than half a degree from global heating. Produced from oil and gas operations and coalmines, and from animal husbandry and natural sources – such as decaying vegetation – methane is a greenhouse gas about 80 times more powerful than carbon dioxide. But it lasts only for about 20 years before degrading into CO2.
