The challenge of extreme heat: The world’s first Chief Heat Officers take action in the face of climate change’s most lethal phenomenon.

When the governor of Santiago, Chile, Claudio Orrego, received an invitation from the Adrienne Arsht-Rockefeller Foundation Resilience Center to participate in an alliance of cities, extreme heat was not on his radar, he said. “Our focus was on other components of climate change: droughts, floods,” he said.  Once he understood the enormous and lethal effect of the phenomenon, he decided not only to join the alliance, but to have a visible and active commitment. That is why he appointed the first Chief Heat Officer in South America.
