### But here we are, as far as I know, again leaving the area of scientific
consensus. There is no agreement as to the likely scope of changes due to
warming, and analyses of what would need to be done to prevent such putative
outcomes are hypotheticals built on hypotheses. Indeed, in view of the
positive agricultural effects of increased carbon dioxide, described in
recent articles in Science and other journals, the best course of action
might be not doing anything about warming in general, but rather dealing
with the possibly quite limited, local deleterious side effects, if any.
