Overview and summary. Interoduction (The focus of SMIC ; The present status of knowledge ; The audiences for the SMIC Report ; Some financial implications of the SMIC recommendations ; Some institutional implications of the SMIC recommendations) ; Major conclusions and recommendations (Previous climate changes ; Man's activities influencing climate ; Present theory and models of climate change ; Effects of man-made surface changes ; Modification of the troposphere ; Modification of the stratosphere) -- Climate and man in perspective. Fundamentals of climate change (The purpose of SMIC ; Definition of climate ; Brief outline of climatic history ; Processes governing the state of the atmosphere) ; Man's activities influencing climate (On predicting the future ; Atmospheric contamination ; Energy production and release ; Land-surface alterations ; Manipulation of surface and underground water ; Weather modification ; Transportation ; The case of the Arctic Ocean ice) -- The theory of climate. Factors governing the climate (Introduction ; Radiative processes ; Ocean-atmosphere transport processes ; Hydrological processes ; General conclusions ; Some implications for implementation of the recommendations) ; The general theory of climate and climate modeling (The physical and mathematical basis of climate theory ; Determinism of climate ; Theoretical models of climate ; Global-average mathematical models ; Feedback mechanisms ; Statistical formulations of climate theory ; Semiempirical theories of climate ; More general mathematical models - explicit treatment of large-scale dynamics ; General conclusions) -- Effects and impacts. Climatic effects of man-made surface change (Modification of the microclimate ; Snow and ice cover ; The oceans ; The land ; Climatological census ; General conclusions) ; Modification of the troposphere (The planetary radiation field and global albedo ; Particles in the atmosphere ; Sources of particles ; Removal of particles and trace gases ; Particle size distribution ; Spatial distribution and trends of particle concentrationss ; Particles and the radiation field ; Gaseous components ; Cirrus clouds ; Some implications for implementation of the recommendations) ; Modification of the stratosphere (Introduction ; Stratospheric injections by high-flying aircraft ; Stratospheriuc transmission of ultraviolet radiation ; Stratospheric ozone in the oxygen-nitrogen-hydrogen atmosphere ; Sources and sinks of trace gases other than ozone ; Particles in the stratosphere ; General conclusions ; Recommendations ; Some implications for implementation of the recommendations). Results of a 3-week intensive examination of the present and potential climatic effects of man's activities by 30 of the world's leading atmospheric scientists from 14 countries.
