Dams can have both positive and negative impacts on climate change. On the positive side, dams can help reduce carbon dioxide emissions by controlling floodwaters and providing irrigation for agriculture, which can reduce the amount of land cleared for farming and subsequent CO2 emissions. Dams can also help store additional water to be used in times of drought, meaning less water needs to be used from other sources.

Additionally, dams can cause changes in the landscape upstream and downstream, affecting the ecosystems and patterns of water flow which ultimately can impact local climate.
