Wallace Smith Broecker

Wallace Smith Broecker was an influential American geophysicist and climate scientist, renowned for his work on climate change and ocean circulation. He coined the term “global warming” in 1975, highlighting the impact of human activity on Earth’s climate. Broecker is best known for his research on the role of oceans in regulating the climate, particularly through the “conveyor belt” system, which describes how ocean currents distribute heat around the planet. His pioneering studies helped raise awareness of climate change and its potential consequences, making him a key figure in understanding our environment and its future.
