Rainforest rainfall originates largely from local evapotranspiration
the verdict
SUPPORTED
the evidence backs this
confidence 82/100
Evidence from multiple hydrological and climate studies confirms that rainforest rainfall relies heavily on local evapotranspiration and moisture recycling, meaning widespread deforestation directly diminishes regional precipitation.
