Deforestation can impact local climates in several ways. Trees play a crucial role in regulating temperature and humidity through processes like transpiration and evaporation. When forests are cleared, the land loses its ability to absorb and retain water, leading to increased surface temperatures and reduced precipitation. This can result in altered weather patterns, such as decreased rainfall and increased drought conditions. Additionally, deforestation can contribute to an increase in greenhouse gas emissions, further exacerbating climate change on a local and global scale.
