Climate change: The heat is on

PROOF OF HUMAN-MADE climate change was first discovered in the 1960s by geochemist Charles Keeling, who measured carbon dioxide (CO2) in the Earth’s atmosphere and detected an annual rise. However, it’s wasn’t until the 1980s, journalists conclude, that the science behind the phenomenon was widely accepted as indisputable and existential. In honour of this recognition, in 1988, US TIME magazine named their Man of the Year as 'Planet of the Year: Endangered Earth'.
