This is how the global warming paranoia has been building. Everything is now blamed on global warming - floods, droughts, heat waves, blistering cold, thunderstorms, tornados, typhoons, hailstorms, excessive snowfall, no snowfall at all, first time snow ever (Kathmandu, Nepal), dormant volcanoes errupting, dormant volcanos not errupting, earthquakes, landslides, glacial melts, glacial build ups, animal migration, bird migration...
And there is no need to prove anything. Its just global warming.
errupt = erupt.
