The ability of the worlds forests to sequester carbon dioxide may come to a halt if global temperatures continue to rise, according to 35 of the worlds top forestry scientists. In fact the scientists predict that in the coming decades, forests could actually release large amounts of CO2, adding to the global warming problem rather than helping to slow it.
