The extreme heat caused illness, death, crop losses, and strained energy and healthcare systems, according to the analysis from World Weather Attribution, Climate Central and the Red Cross.

“Although floods and cyclones often dominate headlines, heat is arguably the deadliest extreme event,’ the report said.

Many heat-related deaths are unreported or are mislabelled by other conditions such as heart disease or kidney failure.
