Several environmental organizations, boosted by the popular movie «Gasland,» have claimed that using hydrofracturing can endanger public water supplies, in part because of potentially toxic chemicals that are sometimes used to help extract the gas.
If so, the interaction between hydrofracturing and ice - cliff collapse could drive global sea level much higher than projected in the Intergovernmental Panel on Climate Change (IPCC)'s 2013 assessment report and in a 2014 study led by Kopp.
«By analyzing the basic physics underlying gas recovery from hydrofractured wells, we calculated a single curve that should describe how much gas comes out over time, and we showed that production from thousands of wells follows this curve,» Marder said.
For example, some exciting work being done by David Pollard and Rob DeConto suggests that processes such as ice - cliff collapse and ice - shelf hydrofracturing may play important roles in future ice sheet behavior that have not been well incorporated into most ice sheet models.
Releasing a huge iceberg, by itself, is a normal process, unrelated to warming, but increased calving may occur in the future if the ice shelf continues to thin, which would make it susceptible to plate bending and hydrofracture processes21.
And older climate models did not include dynamic ice sheet vulnerabilities — like high latent - heat ocean water coming into contact with the submerged faces of sea - fronting glaciers, the ability of surface melt water to break up glaciers by pooling into cracks and forcing them apart (hydrofracturing), or the innate rigidity and frailty of steep ice cliffs which render them susceptible to rapid toppling.
These approaches, however, haven't taken into account some physical processes that can quickly increase ice sheet discharge, such as the collapse of terminal ice cliffs and the breakup of floating ice shelves caused by a process known as hydrofracturing.
