Wallace S. Broecker was a prominent American geoscientist known for his significant contributions to the field of climate science.
He is widely recognized for his pioneering work on the mechanisms that drive climate change and his efforts to raise awareness about the urgency of addressing this issue.
Three of his greatest contributions to science are:
He coined the term "global warming" to describe the increase in Earth's average surface temperature caused by rising levels of greenhouse gases, particularly carbon dioxide.
He introduced the concept of the "ocean conveyor belt," a global ocean current that circulates heat and nutrients around the world, which plays a crucial role in regulating Earth's climate.
He developed a method for using radiocarbon dating to study the movement and mixing of water in the oceans, which has provided important insights into ocean circulation patterns and the global carbon cycle.
Broecker was also a strong advocate for action on climate change and helped raise awareness of the issue among policymakers and the public. He received numerous awards and honors throughout his career, including the National Medal of Science in 1996.
