Apes Climate Change

Although levels of CFCs in the atmosphere are much lower than those of CO2 , CFCs are still potent greenhouse gases because they

• remain in the atmosphere for only a brief time

• lack natural sources

• are much more efficient at absorbing thermal radiation

• are more difficult to remove from smokestacks and tailpipes

Which of the following best describes the mechanism of the greenhouse effect in Earth's atmosphere?

• Infrared radiation from Earth's surface is absorbed by gases in the atmosphere.

• Cosmic radiation from deep space is absorbed by gases in the atmosphere.

• Alpha radiation from the Sun is absorbed by water vapor in the atmosphere.

• Ultraviolet radiation from the Sun is absorbed by ozone gas in the stratosphere.

As greenhouse gasses increase, what happens to Earth's temperature?

• Increase

• Decrease

• Stays the Same

• No Trend

Imagine Grandpa and Dad are discussing global efforts to combat climate change. Grandpa asks, 'What is the significance of the Paris Agreement?' How should Dad respond?

• It aims to increase global temperatures by 2 degrees Celsius

• It is a commitment to reduce coal usage by 50% worldwide

• It is an agreement to strengthen the global response to climate change

• It focuses solely on reducing emissions from transportation

During a family discussion, Grandpa argued that the primary cause of recent global climate change was not natural phenomena but something else. What did Grandpa identify as the primary cause?

• Solar radiation variations

• Orbital changes of the Earth

• Volcanic eruptions

• Human activities

Trees play an important role in the carbon cycle by absorbing carbon dioxide from the atmosphere during photosynthesis and storing it in their biomass. Now, imagine Grandpa owns a large piece of land and decides to clear all the trees on the land to create space for a new farm. Considering the role trees play in regulating atmospheric carbon dioxide, what is the most likely impact of this action on climate change?

• It decreases the amount of carbon dioxide in the atmosphere

• It increases the Earth's albedo

• It increases the amount of carbon dioxide in the atmosphere

• It has no significant impact on climate change

• Increase in global temperatures

• Increase in polar ice caps size

• Decrease in sea levels
