Atmospheric change issues : British Columbia perspective / Scientific Services Division, Atmospheric Environment Service, Pacific Region. Edited by Eric Taylor. : En57-45/91-2E-PDF

"We are significantly changing the earth's atmosphere. Carbon dioxide concentrations have increased 25% over pre-industrial levels; methane concentrations have doubled in the last 200 years; and chlorofluorocarbons (CFCs) releases are increasing by 5-7% each year. Scientists are observing seasonal "holes" in the ozone layer over both polar regions. The future implications of global atmospheric change for agriculture, forestry, wildlife, and human settlements are disturbing. At the local level, urban air pollution is a threat to human health. Atmospheric change is a serious problem requiring serious responses. Significant changes are needed in development policies and planning. Although such changes may initially be difficult or expensive to accomplish, in the long run the benefits of these changes are likely to exceed the costs"--Page 1.
