In fact we have already done so using nothing more than muscle power. Look at
how many areas -- including the fertile crescent -- have been desertified by
human presence. We probably began affecting climate when we discovered fire and
began large scale burns to clear brush and move game animals towards hunters,
by increasing the area of grasslands. One should not forget that the salt pan
deserts of southern Iraq were once the blooming agricultural heartland of
ancient Sumeria. And that northern Iraq and much of the entire region was
covered by ancient cedar forests.
Humans have been altering the face of the earth on a large scale since at least
as far back as the beginning of agriculture and I suspect even much earlier
than that when we learned to control fire and began to use it to shape our
environment.
