If the present concentration of CO₂ doubles in 100 years,and climate models predict that for the earth's average temperature to rise 5°C,what gas must also increase in concentration? A) nitrogen B) oxygen C) methane D) water vapor

Question

Quizplus · Accepted Answer

The climate models predict a rise in temperature, which is typically caused by an increase in greenhouse gases that trap heat in the atmosphere. While CO₂ is a greenhouse gas, it is not as prevalent as water vapor, which is already present in significant amounts. Therefore, for the average temperature to rise 5°C, water vapor would need to increase in concentration along with other greenhouse gases. Nitrogen and oxygen are not greenhouse gases, and methane is not as abundant as water vapor in the atmosphere.
