Released on Wednesday (15 April), the map records 335 extreme weather and trends from 308 individual scientific papers or rapid studies.
The map considers extreme weather events such as heatwaves, flooding or droughts, identified by a colour key. The colours indicate whether the attribution study found a link to human-caused climate change or not, with red indicative of human influence, blue showing no human influence and grey being inconclusive.
The analysis from Carbon Brief revealed heatwaves account for 47 per cent of such events, while droughts and heavy rainfall or floods each make up 15 per cent.
The findings claim that 69 per cent of the mapped extreme weather events and trends were found to have been made more likely or more severe by human caused climate change, with 93 per cent of 125 studies looking at extreme heat around the world finding that climate change made these more likely or more severe.
The map was first published in July 2017, with the current edition the third update. Carbon Brief aims for the map to serve as ‘a tracker for the evolving field of “extreme weather attribution”’.
