Periods of exceptional climate change in Earth history are associated with a dynamic response from the solid Earth, involving enhanced levels of potentially hazardous geological and geomorphological activity. This response is expressed through the adjustment, modulation or triggering of a wide range of surface and crustal phenomena, including volcanic and seismic activity, submarine and sub-aerial landslides, tsunamis and landslide ’splash’ waves glacial outburst and rock-dam failure floods, debris flows and gas-hydrate destabilisation. Looking ahead, modelling studies and projection of current trends point towards increased risk in relation to a spectrum of geological and geomorphological hazards in a world warmed by anthropogenic climate change, while observations suggest that the ongoing rise in global average temperatures may already be eliciting a hazardous response from the geosphere.

    • I think that would point less to any anthropogenic linkage rather a natural cycle interrupted or advanced by anthropogenic climate forcing. Global warming in the past was caused by increased volcanic activity. Perhaps its logical to assume that increased geological intensity would lead to a sympathetic cycle of climate increases and that could have some affect on the geosphere. However it's already been pointed out by the USGS that we aren't experiencing a period of heightened seismic activity rather we've just had the unfortunate luck of having more quakes in population centers over the last decade. The actual number and intensity remains the same. As for the Icelandic activity there is a natural volcanic cycle that errupts almost like clockwork. A much larger volcano is likely to errupt next year as it has in every subsequent year that the other icelandic volcano saw activity.

      I'm not sure what you've been reading, but as far as I know, volcanic activity typically causes global cooling due to the ash emitted into the upper atmosphere reflecting solar energy back into space before it has a chance to warm up our atmosphere...

    • Mother Nature, our planet, is beginning to scratch and shake like a dog ridding itself of fleas.
      There is just only so much a planet can take before it retaliates.
