Warming Globe May Increase Volcanic Activity

Every day it seems scientists are uncovering a surprising new consequence of global warming. Today it's volcanic activity according to a report at New Scientist.

It seems like a long-shot, but as ice caps melt and sea levels rise, pressure on the Earth's crust is going to be shifting around. As the stress is relieved in some areas, increased in others, volcanic activity may appear in new places and the frequency of activity in regular spots may increase. For example, in some arctic regions, the period between eruptions may shrink from 58 to 30 years.

According to one expert, "We are going to see a massive increase in volcanic activity globally… if we look back at previous warm periods, that is what happened."

Great blog! Is your theme custom made or did you download it from somewhere?

A theme like yours with a few simple adjustements would really make my blog shine.
Please let me know where you got your theme. Cheers

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
