Understanding Climate Change

Who was the first to suggest that Earth should be much colder based on basic physics?

• John Tyndall

• Eunice Foote

• Svante Arrhenius

• Joseph Fourier

What did Eunice Foote discover about Earth's atmosphere?

• It is primarily responsible for ocean currents.

• It is composed mainly of nitrogen.

• It is unaffected by human activities.

• It acts as a natural blanket trapping heat.

How did John Tyndall contribute to the understanding of climate change?

• He identified human activities affecting the atmospheric blanket.

• He predicted future climate scenarios using computers.

• He discovered the greenhouse effect.

• He calculated the Earth's orbit changes.

What was Svante Arrhenius's significant contribution to climate science?

• He discovered the natural atmospheric blanket.

• He studied the Ice Ages and their causes.

• He developed the first climate model using computers.

• He calculated the warming effect of increased carbon in the atmosphere.

What did Milutin Milankovitch study during World War I?

• The role of water vapor in climate change.

• The causes of the Ice Ages.

• The effects of carbon emissions.

• The impact of industrialization on climate.

What halted the natural slide into the next Ice Age according to the video?

• The discovery of the greenhouse effect.

• The invention of modern technology.

• The Industrial Revolution and increased carbon emissions.

• The natural cycles of Earth's orbit.

What is the potential range of warming by the end of this century?

• 0.5 to 2 degrees Celsius

• 1.5 to 8 degrees Celsius

• 2 to 10 degrees Celsius

• 3 to 15 degrees Celsius

What is one of the biggest reasons we care about climate change?

• It has no impact on human society.

• It is a natural process that cannot be altered.

• It affects only the polar regions.

• Our society is not equipped to handle drastic climate changes.

What was the sea level like during the time of the dinosaurs?

• Completely frozen

• More than 300 feet higher than today

• About the same as today

• Lower than today

What is the main message of the video regarding climate change?

• Climate change is a recent phenomenon.

• The Earth's climate is naturally stable.

• Human activities have no impact on climate.

• Addressing climate change is crucial for human society.
