The topics we were thinking about editing in our group were: - Effects of global warming on marine mammals - Induced seismicity due to CO2 injection - Carbon neutral fuels - Membrane gas separations

We finally decided to focus on Induced Seismicity due to CO2 injection. Plan of edits to make: - Create a section for induced seismicity due to CCS on the induced seismicity Wikipedia page (no section on CCS yet)

- Make a comparison of risks associated with natural gas storage/hydraulic fracturing/ wastewater injection and CO2 sequestration (use examples of Castor gas project in Spain or induced seismicity in Oklahoma due to wastewater injections)

- Describe the importance of understanding induced seismicity due to storing CO2 because the volumes of fluids injected in the case of CCS largely exceed volumes associated with waste water injection (see Figure 1 Verdon, J.P. (2014), Significance for secure CO2 storage of earthquakes induced by fluid injection, 2014, Environmental Research Letters, Vol. 9, doi:10.1088/1748-9326/9/6/064022.)

- Describe Mohr-Coulomb failure criteria and explain how underground injection can lead to an increase in normal stress, shear stress or pore fluid pressure changes leading to failure on an existing fault plane.
