Question

countries around the world are trying to slow down or reverse the effects of climate change. based on what you know about the greenhouse effect, which of the following actions would be likely to slow the rise in earths average temperature?

• remove co₂ from the atmosphere
• add more n₂ and o₂ to the atmosphere
• reflect incoming sunlight back into space
• reduce greenhouse gas emissions

Explanation:

Step1: Analyze the greenhouse effect

The greenhouse effect is caused by greenhouse gases (like \(CO_2\)) trapping heat. Removing \(CO_2\) (a major greenhouse gas) would reduce the heat - trapping ability.

Step2: Consider the role of \(N_2\) and \(O_2\)

\(N_2\) and \(O_2\) are not greenhouse gases. Adding more of them does not directly affect the greenhouse effect.

Step3: Evaluate reflecting sunlight

Reflecting incoming sunlight back into space means less solar energy is absorbed by the Earth, which can lower the temperature.

Step4: Examine reducing greenhouse gas emissions

Reducing greenhouse gas emissions (like \(CO_2\), methane etc.) limits the amount of heat - trapping gases in the atmosphere.

Answer:

remove \(CO_2\) from the atmosphere, reflect incoming sunlight back into space, reduce greenhouse gas emissions
