Earth's magnetic field is also getting weak at this time. The most visible consequence is the undisciplined polar vortex. Instead of remaining high and tight above the poles, it degenerates into "petal" shapes. That allows deep incursions of cold from the poles toward the equator...recall what has happened to Texas the last two years. The other case occurs as well. Warm air can invade the polar regions. Observe the balmy weather enjoyed by Alaska on an intermittent basis.

Thanks, I knew there would be a Freeper that could explain why the Earth has volcanic activity.

I answered my own question:

30% of electricity on the Island of Hawaii comes from this geothermal plant.
