Film summary
The largest volumes of methane on Earth are frozen deep underground. Learn how global warming could melt these stores and start the irreversible process predicted by the Clathrate Gun Hypothesis.Key facts
- Methane is a potent greenhouse gas.
- The compound methane clathrate is found deep within the ocean and beneath the Earth's crust.
- Methane clathrates are also found within permafrost.
- If permafrost melts, vast amounts of methane would escape into our atmosphere, intensifying the greenhouse effect.
