Causes of global warming
Biology · Secondary 3 · Hard · Causes of global warming
A company replaces its diesel generators with new generators that burn natural gas, another fossil fuel. Why does this change still contribute to global warming, even though natural gas burns more cleanly than diesel?
- Burning natural gas still releases carbon dioxide, which traps heat in the atmosphere.
- Natural gas removes oxygen from the air, causing the Earth to heat up.
- Natural gas does not contain carbon, so it cannot form carbon dioxide.
- Only diesel is a fossil fuel; natural gas is completely carbon-free.
