Study finds that African deforestation reduces rainfall over remaining forest via @planetsave

A new study has shown that deforestation in the rainforests of West Africa reduces the amount of rain that falls over the rest of remaining forest. The study, conducted by researchers from the University of Leeds and published in the journal Geophysical Research Letters, is based on the results of simulations run on a Met Office computer that showed rainfall under different land-use conditions. The result showed that by planting crop land in place of the rainforest reduces the rainfall over the remaining forest by approximately 50%. This is due to changes in the surface temperature which affects the formation of rain clouds above. “We already know from satellite observations that changes in land use can have a big impact on local weather patterns. Here we have been able to show why this happens,” said lead author of the study Dr Luis Garcia-Carreras, from the University of...
