What were climate scientists predicting in the 1970s?

What were the majority of climate studies in the 1970s predicting?

• No significant change in climate

• Global cooling due to aerosol emissions

• Global warming due to CO2 emissions

• An impending ice age

What component of industrial emissions causes cooling?

• Methane

• Carbon dioxide

• Nitrous oxide

• Aerosols

What act helped decrease aerosol emissions in the late 1970s?

• The Global Warming Prevention Act

• The Clean Air Act

• The Environmental Protection Act

• The Clean Water Act

Who published a study in 1856 indicating that increasing atmospheric CO2 would increase Earth's temperature?

• James Hansen

• Eunice Foote

• Stephen Schneider

• John Tyndall

What did the Rasool & Schneider (1971) study speculate about aerosol concentration?

• Quadrupling could reduce surface temperature significantly

• Halving would increase global temperatures

• Tripling would cause significant warming

• Doubling would have no effect

What was the common myth about 1970s climate science?

• Scientists had no consensus on climate change

• Scientists unanimously agreed on global warming

• Scientists were unsure about climate change

• Scientists predicted an imminent ice age

What is a straw man argument in the context of climate science debates?

• An argument based on factual evidence

• A strong argument against climate change

• Misrepresenting an opponent's position to make it easier to attack

• An argument supporting climate change

What did Stephen Schneider do upon revisiting his cooling hypothesis?

• Confirmed his original findings

• Retracted the findings based on new data and models

• Published a new theory on global cooling

• Ignored the new evidence

What is the effect of transitioning to renewable energy sources like wind and solar?

• No change in global temperatures

• Increase in aerosol emissions

• Decrease in CO2 emissions

• Increase in global temperatures

What did the 1979 National Academy of Sciences report predict about doubling CO2 content?

• No significant effect on global temperatures

• A decrease in global temperatures

• A global surface warming of between 2°C and 3.5°C

• An ice age within the next century
