Who was the first to demonstrate the greenhouse effect using experiments with gases?

• Guy Stewart Callendar

• Eunice Foote

• Charles Keeling

• John Tyndall

What was a significant challenge Eunice Foote faced in gaining recognition for her work?

• She did not submit her findings to any scientific society

• Her work was presented by someone else and not published in the main scientific proceedings

• Her experiments were not scientifically valid

• Her experiments were conducted in secret

What did Guy Stewart Callendar's data collection in the 1930s reveal?

• Rising temperatures were linked to the burning of fossil fuels

• Climate change is unrelated to human activity

• CO2 levels were decreasing over time

• The oceans absorb all atmospheric CO2

What was the primary focus of Charles Keeling's research?

• The accurate measurement of atmospheric CO2 levels

• The impact of deforestation on global warming

• The relationship between ocean acidity and CO2

• The effect of water vapor on climate

What is the significance of the Keeling Curve?

• It shows the seasonal variation of CO2 levels

• It illustrates the year-on-year increase in atmospheric CO2

• It demonstrates the decrease in CO2 over time

• It predicts future climate patterns
