I would not be surprised if natural disasters topped that number in the 21st century. Hurricanes, earthquakes, volcanoes, tsunamis, pandemics, droughts, floods. Most of them tied to global climate change.

As melting ice caps change the pressure on land masses and weight distribution of the oceans that could trigger earthquakes like have not been seen since the end of the ice age.

Doesn't heat alter magnetic fields? If so, global warming could, conceivably, affect earthquakes and volcanoes by altering the earth's magnetic field. We don't really know what the triggers are. If there is a tie-in it could be even worse.

It's going to be an interesting century.
