A study published by US and Brazilian scientists (from the Smithsonian Tropical Research Institute in Panama and the National Institute for Amazonian Research in Manus, Brazil) says that the Amazon rain forest is being altered by global warming in a way that will prevent the forest from absorbing carbon dioxide. The scientists discovered that the highest trees are spreading larger canopies that are covering lower plant life, as a result of the warming trend. This is causing the slower growing hardwoods to be less able to absorb the carbon dioxide.
