Global Warming and Earthquakes
By: Rowan Wolf
Well as if droughts, tornadoes, hurricanes, and heat waves weren't enough, scientists are now talking about earthquakes and volcanoes being linked to global warming. The theory runs like this. The ice sheets and glaciers are ice, and that weighs a lot - 1 cubic meter weighs a ton. All that ice depresses the crust of the earth. As the ice melts, it causes a rebounding in the crust. On the other hand, the weight transfers to the oceans which increases crustal pressure under the ocean. Therefore, the ice melt caused by global warming shifts weight on the earth's crust resulting in earthquakes and volcanic activity.
Once again, it seems that all things are connected.
