![]() ![]() They called for renewed efforts to protect rainforests and urged world leaders to act on their pledges to stop deforestation. ![]() "Global efforts to restore large areas of degraded and deforested land could enhance precipitation, reversing some of the reductions in precipitation due to forest loss observed here," the authors wrote. Reduced precipitation recycling due to forest loss, the researchers say, has grave repercussions for agriculture, hydropower generation and climate resilience - as well as for the rainforest itself. When trees are cut down, it breaks this cycle, hampering the formation of rain and leading to drought. This process, called precipitation recycling, accounts for up to 41% of the rainfall in the Amazon and up to 50% in the Congo, according to the study's authors. That humid air rises and helps create clouds, which in turn create more rain. They then release that moisture, both through evaporation and through their leaves. When it rains, trees soak up and use that water. The study, published in the journal Nature last month, found that clearing wide swaths of trees - what's known as deforestation - reduces rainfall in tropical rainforests, which actually generate their own rain. A new study has uncovered that forest loss is changing weather patterns in the world's three largest remaining tropical rainforests.
