1。 Carbon Dioxide (CO2):
* 構成： 1つの炭素原子と2つの酸素原子。
* ソース： 化石燃料、森林破壊、産業プロセス。
2。 Methane (CH4):
* 構成： One carbon atom and four hydrogen atoms.
* ソース： Livestock, natural gas leaks, rice cultivation, landfills.
3。 Nitrous Oxide (N2O):
* 構成： Two nitrogen atoms and one oxygen atom.
* ソース： Agricultural activities, industrial processes, burning fossil fuels.
4。 Fluorinated Gases:
* 構成： Various combinations of fluorine, carbon, and other elements.
* ソース： Refrigerants, aerosols, foam blowing agents, fire suppressants.
* 例： HFCs (hydrofluorocarbons), PFCs (perfluorocarbons), SF6 (sulfur hexafluoride)
5。 Ozone (O3):
* 構成： Three oxygen atoms.
* ソース： Naturally occurring in the stratosphere, but also formed from air pollution in the troposphere.
6。 Water Vapor (H2O):
* 構成： 2つの水素原子と1つの酸素原子。
* ソース： Evaporation from oceans, lakes, and rivers, transpiration from plants.
重要な注意： While water vapor is a greenhouse gas, it's considered a "feedback" rather than a direct driver of climate change. This is because its concentration is primarily driven by temperature, rather than human activities.
Let me know if you'd like more details on any specific greenhouse gas!
