To classify the gases you've mentioned into greenhouse gases and non-greenhouse gases:
Greenhouse Gases:
- Carbon Dioxide (CO₂) - A major greenhouse gas produced by human activities, like burning fossil fuels.
- Methane (CH₄) - A potent greenhouse gas with a much higher warming potential than CO₂ over a short time frame.
- Nitrous Oxide (N₂O) - A greenhouse gas emitted from agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste.
Non-Greenhouse Gases:
- Nitrogen (N₂) - A major component of the atmosphere but does not contribute to the greenhouse effect.
- Oxygen (O₂) - Essential for respiration in many organisms but does not act as a greenhouse gas.
- Ozone (O₃) - While ozone in the stratosphere protects the Earth from UV radiation, ground-level ozone is a greenhouse gas. However, it is typically categorized more for its role in pollution rather than as a traditional greenhouse gas.
If you're specifically focusing on the context of climate change impact, the first three (carbon dioxide, methane, and nitrous oxide) would be the significant greenhouse gases, while nitrogen and oxygen are non-greenhouse gases, and ozone can be complex, often depending on its location in the atmosphere.
