Claude Lorius, a leading glaciologist whose expeditions helped prove that humans were responsible for global warming, has died at the age of 91.
Ednews reports citing BBC that he led 22 expeditions to Greenland and Antarctica during his lifetime.
It was during one trip to Antarctica in 1965 where an evening of whiskey with ice cubes led him to prove humankind's role in the heating of the Earth's surface.
Lorius died on Tuesday morning in the French region of Burgundy.
It was his love of adventure which set him on the path to identifying and predicting an impending catastrophe for the planet.
