We often think about human-induced climate change as something that will happen in the future, but it is happening now. Ecosystems and people in the United States and around the world are affected by the ongoing process of climate change today. Climate change affects the environment in many different ways, including rising temperatures, sea level rise, drought, flooding, and more. These events affect things that we depend upon and value, like water, energy, transportation, wildlife, agriculture, ecosystems, and human health.
