Deforestation and rainfall

The Australian Nuclear Science and Technology Organisation said, "less trees, less rain."

Australian scientists plotted the cycle of a heavy molecular version of water common in the Amazon that evaporates more readily through plants than from lakes and rivers and have concluded that deforestation along the Amazon River in South America was reducing rainfall and causing climate change in the region. The study found that a loss of forests meant less water evaporated back into the atmosphere leading to less rainfall.
