In Saudi Arabia, the number of Muslim pilgrims who’ve died amid a searing heat wave in the holy city of Mecca has topped 900, after temperatures this week soared above 125 degrees Fahrenheit. Thousands have been treated for heat exhaustion. Climate scientists warn the risk of heatstroke will continue to rise for the millions of Muslims who make the annual Hajj pilgrimage. This is Fahad Saeed, a scientist at Climate Analytics.

Fahad Saeed: “We must do global action to stop the global warming at 1.5 degrees centigrade. At anything beyond that, we are putting those pilgrims at the risk of death.”

In India, emergency workers have recovered the bodies of more than 50 unhoused people who’ve died over the last two days as daytime temperatures soared above 120 degrees. Indian health officials have logged over 40,000 suspected heatstroke cases so far this year.
