学术报告：Climate change is already impacting all ecosystems on Earth, particularly tropical ecosystems such as Amazonia and tropical forests in general. Increases in temperature and climate extremes, reductions in precipitation, are impacting the functioning of critical ecosystems on Earth. There is a potential for strong positive feedback since Amazonia stores 120 billion tons of carbon in the ecosystem that could be mobilized to the atmosphere. Also, changes in the hydrological cycle and increases in temperatures could enhance methane emissions. Brazil is committed to stop deforestation and reforest 12 million hectares by 2030, which will have important impacts in the Amazonian ecosystem.
