He attended the University of Iowa, where he earned a Bachelor’s degree in mathematics and physics in 1963 with the highest distinction. He went on to earn his Master’s degree in Astronomy in 1965 and his PhD degree in Physics in 1967, both from the University of Iowa.
During his early career, Hansen worked as a postdoctoral researcher at the Goddard Institute for Space Studies (GISS) in New York City. There, he worked on developing computer models to study the Earth’s climate. In 1976, Hansen joined the faculty of Columbia University, where he has remained ever since.
Hansen’s early work focused on understanding the Earth’s climate and how it was changing over time. He was particularly interested in the role of greenhouse gases in the atmosphere and how they were affecting the climate. Hansen’s research helped to establish the scientific consensus that the Earth’s climate was warming and that human activities, such as the burning of fossil fuels, were largely responsible for this warming.
Overall, Hansen’s early life and education set the stage for his groundbreaking work on climate change. His interest in science, particularly in astronomy and physics, led him to study the Earth’s climate and to develop computer models to understand how it was changing.

Career
James Hansen is best known for his research in climatology, his 1988 Congressional testimony on climate change, and his advocacy of action to avoid dangerous climate change. Hansen began his career as a physicist at the Goddard Institute for Space Studies (GISS) in 1967, where he worked on the Pioneer Venus project and conducted research on the Earth’s climate.
In the 1980s, Hansen became increasingly concerned about the potential impacts of global warming, and he began to speak out publicly about the need for action to address the issue. In 1988, he testified before Congress about the dangers of global warming and the need for immediate action to reduce greenhouse gas emissions. His testimony helped to raise awareness of the issue and is widely credited with helping to spur action on climate change.
After his testimony, Hansen continued to work at GISS and to speak out about climate change. He became a vocal critic of the George W. Bush administration’s climate policies, and he was arrested several times for participating in protests against coal mining and other activities that contribute to climate change.
In 2013, Hansen retired from his position at GISS and became an adjunct professor at Columbia University. He continues to conduct research on climate change and to advocate for action to address the issue. Hansen is the director of the Program on Climate Science, Awareness and Solutions of the Earth Institute at Columbia University.
Research and Discoveries
James Hansen is best known for his research in climatology, particularly his work on the greenhouse effect and climate change prediction. He has been a leading voice in the scientific community on the issue of climate change for several decades.
The Greenhouse Effect
Hansen’s early work focused on understanding the greenhouse effect, which is the process by which certain gases in the Earth’s atmosphere trap heat and warm the planet. He demonstrated that human activities, such as burning fossil fuels, were increasing the concentration of these gases, leading to a warming of the planet.
Climate Change Prediction
Hansen’s most famous contribution to climate science was his testimony before the US Congress in 1988, where he predicted that global warming would have serious consequences for the planet. He warned that rising temperatures could lead to sea level rise, more frequent heatwaves, and more extreme weather events.
Hansen’s predictions have largely been borne out by subsequent research. The Intergovernmental Panel on Climate Change (IPCC) has confirmed that global temperatures have risen by around 1°C since pre-industrial times, and that this is largely due to human activities.
Advocacy for Climate Policy
In addition to his scientific work, Hansen has been a vocal advocate for climate policy. He has argued that the only way to prevent catastrophic climate change is to rapidly reduce greenhouse gas emissions, and has called for a price on carbon to encourage this transition.
Hansen’s advocacy has sometimes put him at odds with the political establishment. In 2011, he was arrested outside the White House while protesting against the Keystone XL pipeline, which he argued would increase greenhouse gas emissions. However, he has continued to speak out on the issue, arguing that the risks of inaction are too great.
Awards and Recognition
Throughout his career, James Hansen has received numerous awards and recognition for his contributions to climate science and advocacy.
In 1990, Hansen was awarded the John Heinz Environmental Award in recognition of his efforts to raise awareness about climate change and advocate for action to address it. In 2001, he received the Blue Planet Prize, a prestigious award given to individuals or organizations that make significant contributions to solving global environmental problems.
In 2006, Hansen was named one of Time magazine’s 100 most influential people in the world. The magazine cited his work on climate change as “the most important scientific discovery of our time.”
Hansen has also been recognized by his peers in the scientific community. In 2008, he was awarded the Carl-Gustaf Rossby Research Medal by the American Meteorological Society for his pioneering work in climate modeling and his efforts to communicate the science of climate change to the public.
In addition to these awards, Hansen has received honorary degrees from several universities, including the University of Edinburgh, the University of Leuven, and the University of Massachusetts. He has also been elected to the National Academy of Sciences, the American Academy of Arts and Sciences, and the Royal Society of London.
