Heat Wave 'Lucifer' August 2017
The summer of 2017 in Western Europe and the Euro-Mediterranean region featured a series of major heat waves. Early August saw a particularly intense heat wave — called "Lucifer" — in southeastern countries. The three day heat event broke numerous records, including several all time highs.
An analysis conducted by the World Weather Attribution group in September 2017 found that climate change has made extreme three day heat events like Lucifer four time as likely since 1900.[1]
The increasing frequency and intensity of heat waves is among the most obvious and well documented effects of climate change, according to the National Academy of Sciences. Four out of five record-hot days globally are now attributed to climate change.[2]
