For the second time in two months, western and central Europe has been hit by a record-breaking heatwave.

Temperature records have toppled in multiple countries, with France seeing its “hottest day ever” for two days running and the UK, Spain and Switzerland breaking records for June.

A rapid-response attribution study has concluded that “climate change is unequivocally to blame”, noting that the scorching temperatures would have been “virtually impossible” 50 years ago.

The research also found that the sweltering overnight temperatures seen this week are “100 times” more likely today than they were in 2003 when Europe was hit by a deadly summer heatwave.

The extreme conditions come on the 50th anniversary of a historic 1976 heatwave in the UK, prompting many comparisons of the two events from scientists and the media.
