COPENHAGEN: The World Health Organisation’s European office said on Friday the heatwave baking Europe has caused over 1,700 deaths on the Iberian peninsula alone, calling for joint action to tackle climate change.

“Heat kills. Over the past decades, hundreds of thousands of people have died as a result of extreme heat during extended heatwaves, often with simultaneous wildfires,” WHO regional director for Europe Hans Kluge said in a statement.

“This year, we have already witnessed more than 1,700 needless deaths in the present heatwave in Spain and Portugal alone,” Kluge added.

The regional director stressed that exposure to extreme heat “often exacerbates pre-existing health conditions” and noted that “individuals at either end of life’s spectrum - infants and older people - are at particular risk”.

Responding to a query, WHO Europe explained that the figure is a preliminary estimate based on reports by national authorities, and that the toll had “already increased and will increase further over the coming days”.

The true number of deaths linked to the heatwave won’t be known for weeks, he said, adding “this scorching summer season is barely halfway done”.

“Ultimately, this week’s events point yet again to the desperate need for pan-European action to effectively tackle climate change,” Kluge said.
