Climate forcing of geological and geomorphological hazards

Bill McGuire, Richard Betts, Christopher Kilburn, Mark Maslin, David Pyle, John Smellie and David Tappin
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. Papers included in this issue review the potential influences of anthropogenic warming in relation to an array of geological and geomorphological hazards across a range of environmental settings.
