Wild Card's description: 

We know in the past there have been great belches of methane, followed by a climate spike. The American coastline has had a lot of extra erosion because of extra agricultural production and there could be a landslide. This would move at 200 or 300 miles an hour, causing a major ‘outgassing’ of methane.
