Broecker died Monday in New York, said Kevin Krajick, science editor of the Earth Institute of Columbia University.

Broecker has spent many years as a professor at Columbia and his extensive work focuses on the relationship between oceans, climate and geological time.

In 1975, he published an article titled "Climate Change: Are We on the Edge of a Pronounced Global Warming?"

Although the term has been used before, the use of Broecker has helped to propel it into the mainstream.

Broecker and his work are also behind other well-known climate concepts, such as the "Global Ocean Conveyor Belt", which links deep ocean movements with changes in the atmosphere.
Broecker appeared on CNN Newsroom in 2009 to talk about the warning signs of climate change revealed by his research.

"I base my fears for the future not on what is happening, but on the fact [that] that physics tells us that if we put these gases in the atmosphere, we will warm the planet, "he said. If we are wrong about this, we are in the left field of everything. "
