The climate crisis is one of the biggest threats to global health of the 21st century1 because climate change is accompanied by numerous medical consequences.2 We are already seeing these negative global health impacts due to excessive ambient temperatures and air pollution. One notable episode was the extreme heatwave in Europe in summer 2003, which resulted in approximately 70,000 more deaths across Europe, of which 20% in London and 70% in Paris were attributed to human-induced or anthropogenic climate change.
