Melting Arctic Ice is Releasing Massive Amounts of Methane

The melting Arctic ice is causing huge quantities of methane gas to be released into the atmosphere. Concerns about climate change-inducing greenhouse gases are often centered on carbon dioxide (CO2), but methane is a greenhouse gas that is 20-30 times more potent than CO2. Each methane molecule is actually about 70 times more potent in terms of trapping heat than a molecule of carbon dioxide, however, methane breaks down more quickly in the atmosphere than carbon dioxide.
