Environmental effects of increased atmospheric carbon dioxide
Willie Soon1,*, Sallie L. Baliunas1, Arthur B. Robinson2, Zachary W. Robinson2
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
