Trees may be saving our bacon, and preventing our bakin'. New research shows that global warming has increased the growth in the surviving tropical forests. That in turn means the trees there are absorbing CO2 at a much higher rate than anticipated, thus helping thwart the CO2 build-up that warms the atmosphere. Tolkein was onto something. In his LORD OF THE RINGS the ents--huge tree creatures--show up to crush enemies of the hobbits and their allies. Now it appears that real-life ents--huge trees--could be saving us, whether we deserve it or not. Scientists estimated that the increased carbon absorption in African forests equals the amount of carbon gthe US puts into the atmosphere. Now if we could just find mofre forests to absorb all the CO2 pouring out of China as well.
