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

Explanation:

• Reduce greenhouse gas emissions: Greenhouse gases like \(CO_2\), \(CH_4\) trap heat. Reducing their emissions means less heat is trapped, slowing temperature rise.
• Remove \(CO_2\) from the atmosphere: Less \(CO_2\) (a major greenhouse gas) in the atmosphere reduces the greenhouse effect, as there is less gas to trap heat.
• Reflect incoming sunlight back into space: If less solar radiation is absorbed by the Earth (because it is reflected back), the overall energy input to the Earth - atmosphere system is reduced, which can slow the temperature rise.
• Adding more \(N_2\) (nitrogen) and \(O_2\) (oxygen) to the atmosphere is not effective. \(N_2\) and \(O_2\) are not greenhouse gases (they do not trap heat in the way that \(CO_2\), \(CH_4\) etc. do).

Answer:

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