You are not understanding what I am saying. In the article they make the claim that global warming is causing volcanos becuase of the reduced glacier sheets over the volcanic craters. The theory is that with decreased pressure over the creaters you have an increased chance of the pressure under the glaciers to prodcue volcanic activity. So where are the gl ...[text shortened]... cle should point to increased earthquakes, not increased volcanic activity in the Mediterranian.
1. The study observed a 80,000 year period. Because few glaciers exist today in the Mediterranean doesn't mean there weren't some a long time ago. Also, given that they did melt (if there were any there), it doesn't surprise me that there's few left now.
2. Thermal expansion is another factor that affects sea level rise. It doesn't require glaciers, just warmer weather.
With the changing dynamics in the crust, faults could also be destabilized, which could bring a whole host of other problems.
"It's not just the volcanoes. Obviously if you load and unload active faults, then you're liable to trigger earthquakes," McGuire told LiveScience, noting that there is ample evidence for this association in past climate change events.
