Human-caused climate change is "unequivocally" responsible for the intensity of a record-breaking heatwave scorching Europe, scientists said Friday, while experts consider the costs for an economy as productivity melts and growth becomes lethargic.
It would have been "virtually impossible" for such exceptional temperatures to occur in June fifty years ago, the World Weather Attribution group of scientists said.
A similar heatwave would have been 3.5C cooler during the day in June 1976, concluded the study by scientists from Europe, the United States and the United Kingdom.
But the world is hotter today and "the chance of a heatwave like this has changed immensely", said the study's lead author Theodore Keeping from Imperial College London.
