Question

most modern forms of transportation are powered by fossil fuels. carbon dioxide, methane, carbon monoxide, and other gases are released into the atmosphere during the production and combustion of these fuels. how might these gases cause climatic changes?
a. these gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere
b. these gases have no effect on atmospheric temperatures, so they are unable to cause any type of climatic changes
c. these gases block solar radiation, making the atmosphere cooler than it would otherwise be
d. these gases cause more water vapor to condense, making climates wetter than they were in the past

Explanation:

二氧化碳、甲烷等气体是温室气体，它们能减少热能量向太空逃逸，使大气变暖，引发气候变化。

Answer:

A. These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere
