344 TITUS, J. G. (Editor) 1986. Effects of Chanp:es in Stratospheric Ozone 

 and Global Climate . Volumes 1-4. United States Environmental Protection 

 Agency, United Nations Environment Program. 



This report examines the possible consequences of projected changes in 

 stratospheric ozone and global climate resulting from emissions of 

 chlorofluorocarbons, carbon dioxide, methane, and other gases released by 

 human activities. 



The four volumes of this report comprise the proceedings of a 

 conference, "International Conference on the Health and Environmental Effects 

 of Ozone Modification and Climate Change", sponsored by U.S. Environmental 

 Protection Agency and by the United Nations Environment Program. 



Several noteworthy articles include: 



(a) Robert H. Thomas, "Future Sea- level Rise and Its Early Detection by 

 Satellite Remote Sensing", presents new calculations of the possible 

 contribution of Antarctica, and combines then with previous estimates for the 

 other sources, projecting that a worldwide rise in sea- level of 90 to 170 

 centimeters by the years 2100 with 110 centimeters most likely. 



(b) Per Bruun, "Worldwide Impact of Sea-level Rise on Shorelines", 

 argues that with a combination of coastal engineering and sound planning 

 society can meet the challenge of a rising sea. He discusses a number of 

 engineering options, including dikes (levees) and seawalls, and adding sand to 

 recreational beaches that are eroding with a section on the battle that the 

 Dutch have fought with the sea for over one thousand years. 



(c) Eric C.F. Bird, "Potential Effects of Sea-level Rise on the Coasts 

 of Australia, Africa, and Asia," examines the implications of sea-level rise 

 for other African and Asian nations, as well as Australia. 



(d) Stephen P. Leatherman, "Coastal Geomorphic Impacts of Sea-level 

 Rise on Coasts of South America", examines the implications of sea-level rise 

 for South America. 



(e) Richard A. Park, et al., "Predicting the Effects of Sea-level Rise 

 on Coastal Wetlands, "focus on the expected drowning of coastal wetlands in 

 the United States. Using a computer model of over 50 sites, they project that 

 40-75 percent of existing U.S coastal wetlands could by lost by 2100.

For the last several thousand years, sea- level has risen so slowly that, 

 for most practical purposes, it has been constant. This slow rate of rise has 

 enabled coastal wetlands to be far more extensive than was possible when sea- 

 level was rising rapidly. However, recent developments suggest that rising 

 sea-level may increasingly threaten coastal wetlands in the future. Evidence 

 of wetland loss from current sea- level trends is confined to a few areas. 

 Wetlands in Louisiana are converting to open water at a rate of 40 square 

 miles per year largely because relative sea- level is rising one inch every 

 three years. (Tidal gages measure relative sea- level rise, which equals land 

 subsidence plus world-wide sea-level rise.) Along the Eastern Shore of
