Follow-up on Geoengineering

When I read through the article on geoengineering in the current issue of Science Illustrated (see We Are in God's Hands below), I found that some of the ideas scientists and engineers are proposing to help slow down global warming are pretty good. One of these ideas is to line highways with artificial trees, each of which could remove 1,000 times as much carbon dioxide from the air as a natural tree. These contraptions would be no substitute for planting natural trees, but they are much safer and would be a lot more effective than any of the other geoengineering ideas being floated. As even the geoengineers admit, reducing carbon emissions is the best way to counteract artificial global warming.
