1) Humans are releasing about 10 Gigatons of carbon into the atmosphere in the form of carbon dioxide (36 Gt of CO2) a year. List 3 impacts of this release and provide evidence for how the impacts are related to CO2 (for example, wildfires are related to drought which is caused by increased evaporation due to warmer global and regional temperatures related to increased atmospheric CO2).

2) What are the positive and negative impacts of fracking? Should fracking be banned? How should we dispose of fracking fluids and what is the impact of disposal (Google “Oklahoma fracking”)? Should it be mandatory for government agencies to provide the public with accurate scientific information, regardless of economic consequences?

3) Is nuclear energy a safe method for energy production? Should we be building more nuclear plants as a low-carbon emission alternative for power plants? What are the major concerns with nuclear energy?

4) How do you view the development of offshore wind farms? Comment on this specific case.
