Gupta, R. S. 2004. Introduction to Environmental Engineering and Science, 2nd ed. Rockville, MD ABS Consulting, Government Institute. An introduction to the fundamental principles common to most environmental problems is followed by major sections on water pollution, hazardous wastes and risk assessment, waste treatment, air pollution, global climate change, and hazardous substances. Includes problems to develop skills learned in the text. 

Global hazard examines adverse consequences that occur on a larger scale area and include stratospheric ozone depletion and effects of chemicals on global climate change. 

Natural gas hydrates in sediments are widely distributed in offshore continental margins and in polar regions. The amount of methane contained in gas hydrates is currently estimated to be between 10 and 10 m (Kvenvolden, 2000), considered an important natural resource in the future. Natural gas hydrates are also believed to be a factor in global climate changes (Haq, 2000) and submarine geologic hazards (Paull et al, 2000b).

A discipline that had begun to address drinking water and wastewater treatment issues expanded and now encompasses groundwater, stormwater, estuarine environments, aquatic ecology, desalination, hazardous wastes and solid wastes, acid deposition, smog, chlorofiuorocarbons, indoor air quality and hazardous air pollutants, and global climate change. 

Another level of uncertainty that affects current hazard mapping and risk scenarios is generated by future sea-level rise. The IPCC AR5 (International Panel on Climate Change— Fifth Assessment Report, accessible at htqj // www.ipcc.ch/) contained several statements with a global average increase between 0.2 and 0.8 m in last 30 years. However, several studies suggest that future local amplitude could exceed 2 m based on paleo-chmatic evidence (EEA 2012). 

Altogether, in contrast to the global trend, the regional-scale climate projections predict only moderate changes within the next decades. Therefore, the hazard due to harsh weather conditions is not expected to increase significantly on a medium-term scale.
