The global warming process may be even more intense than originally forecast unless deforestation can be halted, especially in the tropical regions. This warning has been published in Nature Communications by an international group of scientists. “If we go on destroying forests at the current pace—some 7,000 km² per year in the case of Amazonia—in three to four decades, we’ll have a massive accumulated loss. This will intensify global warming regardless of all efforts to reduce greenhouse gas emissions,” said Paulo Artaxo, a professor at the University of São Paulo’s Physics Institute (IF-USP).
