Mapping extreme events attributed to climate change

Mapping extreme weather events
Different symbols show the type of extreme weather; a heatwave, flood or drought. The colours indicate whether the attribution study found climate change played a role in the event.

In 138 peer-reviewed studies scientists have attributed the change in severity or  frequency of 144 extreme weather events to climate change and other causes.   The weather events scientists have studied so far are not a random statistical study – they include high-impact events like Hurricane Sandy or simply the events that occurred nearest to scientific research centres.  Combining the evidence over the past 20 years, the literature is heavily dominated by studies of extreme heat (34%), drought (23%) and rainfall (20%). Together, these make up more than three quarters of all published studies (77%).   The extreme events have been mapped across the Earth’s geography.  Carbon Brief mapping extreme events
