Last June, September and October were all logged as the warmest ever, world-wide. The past 10 years are all in the warmest 10 ever recorded, apart from 1996 whose place is taken by 1990.
This year Arctic sea ice dropped to its smallest ever extent, the Atlantic suffered a record hurricane season and an unprecedented drought reduced the flow of the Amazon to its lowest ever level. Canada and Australia had their hottest ever weather this year, while India, Pakistan, Bangladesh and Algeria suffered heatwaves touching 50C.
