1For the purposes of discussion in this paper, we will use carbon dioxide as a surrogate for itself and the other minor GHGs that have been associated with the global warming hypothesis. Greenhouse warming models usually assume that the input
of all the minor GHGs produces an effect roughly twice that of CO2 alone
ABSTRACT: A review of the literature concerning the environmental consequences of increased levels of atmospheric carbon dioxide leads to the conclusion that increases during the 20th century have produced no deleterious effects upon global climate or
temperature. Increased carbon dioxide has, however, markedly increased plant growth rates as inferred from numerous laboratory and field experiments. There is no clear evidence, nor unique attribution, of the global effects of anthropogenic CO2
on climate. Meaningful integrated assessments of the environmental impacts of anthropogenic CO2 are not yet possible because model estimates of global and regional climate changes on interannual, decadal and centennial time scales remain
highly uncertain.
KEY WORDS: Global warming · Carbon dioxide · Atmospheric and biological effects
