Climate change is when the temperature of the Earth's atmosphere changes and it can cause things like floods, droughts, heat waves, hurricanes, and other extreme weather events. The United States has a climate change policy which is a set of laws and rules to help reduce the amount of climate change. Some of these policies include things like setting limits on how much carbon dioxide companies can emit into the air, investing in clean energy, planting trees, and encouraging people to reduce their energy use. The goal is to reduce emissions so the Earth's temperature doesn't continue to rise, which will help keep the climate stable and protect our planet.
