claim: In their worst-case scenario, the sea level could rise by six feet by the end of this century, and the pace could pick up drastically in the 22nd century.
evidence: Some of the main human activities that contribute to global warming are: increasing atmospheric concentrations of greenhouse gases, for a warming effect global changes to land surface, such as deforestation, for a warming effect increasing atmospheric concentrations of aerosols, mainly for a cooling effect In addition to human activities, some natural mechanisms can also cause climate change, including for example, climate oscillations, changes in solar activity, and volcanic activity.
