Yes, it’s true… scientists have evidence supporting the widespread perception that trees make rain, that by growing more vegetation, we get more rain.
On average, 40% or more of the precipitation over land originates from evaporation and the transpiration of water from vegetation. Forests like the Amazon don’t merely grow in wet areas; they create and maintain the conditions in which they grow by increasing rainfall and reducing the length of the dry season.
Trees and forests increase rainfall intensity through the fungal spores, pollen, bacterial cells and other particles they release into the atmosphere. Atmospheric moisture condenses when the air becomes sufficiently saturated with water and does so much more readily when these particles are present.
When vegetation gets cleared, wet seasons come later, and less water is available in the landscape for evaporation and transpiration, suppressing precipitation.
