YES - Climate Change affects tectonics!

All around the globe there are many points where tectonic plates are straining against each other and need only a slight change in temperature or weight to cause a slip. If the oceans rise by a millimeter how much weight shift is that? Think about it.

Looking back to other periods in our planet's history when the climate was swinging about wildly, most notably during the last ice age, it appears that far more than the weather was affected. The solid earth also became restless, with an increase in volcanic activity, earthquakes, giant submarine landslides and tsunamis. At the rate climate change is accelerating, there is every prospect that we will see a similar response from the planet, heralding not just a warmer future but also a fiery one. Guardian UK
