Question 1

True or false: James Hansen's first climate testimony in 1988 helped spark widespread public awareness of global warming.

Accepted Answer

True. His dramatic Senate testimony during a heatwave put climate change on the national agenda, making him a key figure in climate science history.

Question 2

True or false: James Hansen originally trained as a chemist before switching to climate physics.

Accepted Answer

True. He earned a PhD in physics from the University of Iowa, not chemistry. His early work focused on Venus's atmosphere, which informed Earth climate models.

Question 3

True or false: Hansen has consistently argued that carbon dioxide reduction alone is enough to solve the climate crisis.

Accepted Answer

False. He famously advocates for a carbon fee-and-dividend system plus nuclear power and geoengineering, not just CO2 cuts. He calls for broader action.

Question 4

True or false: James Hansen was awarded the Nobel Peace Prize in 2007 for his climate research.

Accepted Answer

False. The 2007 Nobel Peace Prize went to the IPCC and Al Gore, not Hansen individually. He has received other major awards but not the Nobel.

Question 5

True or false: Hansen has endorsed a global carbon tax with 100% dividend returned to citizens as his primary policy solution.

Accepted Answer

True. He strongly supports a 'carbon fee and dividend' model, arguing it's economically efficient and politically feasible to transition off fossil fuels.

Question 6

True or false: Hansen believes that human-made aerosols have a net cooling effect that masks some global warming.

Accepted Answer

True. He has published research showing sulfate aerosols offset about 0.5°C of warming, a key nuance in understanding past and future climate sensitivity.

Question 7

True or false: James Hansen was the first scientist to use the term 'global warming' in a peer-reviewed paper.

Accepted Answer

False. The term appeared in scientific literature earlier, notably by Wallace Broecker in 1975. Hansen popularized it but didn't coin it.

Question 8

True or false: Hansen was arrested in 2011 while protesting the Keystone XL pipeline outside the White House.

Accepted Answer

True. At age 70, he was handcuffed along with other activists, drawing significant media attention to the fight against tar sands oil extraction.
