There is no clear evidence, nor unique attribution, of the global effects on climate of CO[subscript 2] resulting from human activities. Meaningful assessments of the environmental impacts of such anthropogenic CO[subscript 2] are not yet possible because estimates derived from models simulating global and regional changes in climate on interannual, decadal, and centennial time-scales remain highly uncertain.
