A study from an international team of scientists sheds some light on one of the biggest mysteries in climate science. What happens to the 8 billion tons of carbon emissions resulting from motor vehicles, factories, etc. each year? Earlier estimates indicated that forests in the northern regions were responsible for a good portion of the carbon uptake. New information from aircraft samples reveals those numbers to be much lower, but it appears that forests in the tropical regions are doing significantly more than expected to offset the industrial emissions. Not exactly a K.O. (or should we say CO) of global warming, but certainly one round for the tropics in this fight.
