... The potential magnitude cf the consequences for humanity of possible climatic changes makes this a subject deserving the concerted attention of both the research community and those charged with protection of the environment. The situation is complicated by the fact that many of the possible man-made changes in climate that have been considered are global in character.

From page 35...
... National and international policies defining acceptable limits on the use of fossil fuels must be established within that span. Such definitiors must be based on reliable estimates of the magnitude cf changes that might occur in global temperatures and consequent changes in climate, polar ice cap masses, and sea level.

... The social and political consequences cf possible regulatory actions also need to be studied, particularly if fertilizer use should be affected, and the international aspects of control measures must be taken into account. Although the causes of the perturbations could originate in any or all countries, the deleterious effects, at least those directly concerned with human health, are likely to be limited in their occurrence to a relatively small geographic area (see NRC 1975a, Appendix C: 177-221)

... The greatest information need in this area is probably or the biological and economic consequences of acidified precipitation and weather modification by sulfur and particle emission, which would need to fce balanced against the biological and social impacts of using more expensive low-sulfur fuels. INSTITUTIONAL AFBANGEMENTS Given the present state cf krowledge, research on possible perturbations of weather ard climate by environmental modifications cannot, in general, be separated from other aspects of climate research.

... The CIAP studies emphasized the international nature of problems; continuation of this aspect is essential if future regulatory action is contemplated. fcithin EPA, research on sulfur emissions at present has high priority at all levels, from techniques of fuel desulfurization to field observations cf transport and transformation of the emissions and consequent weather modification, A large, well-conducted field experiment with funding from EPA, NSF and state sources is continuing in the St.
