Climate models are computer simulations that are used to predict and understand the behavior of Earth's climate system. These models use mathematical equations to represent the interactions between the atmosphere, oceans, land surface, and ice, and how they influence each other over time. By inputting data on factors such as greenhouse gas emissions, solar radiation, and ocean circulation patterns, climate models can forecast future climate change scenarios and assess the impacts of different mitigation and adaptation strategies. These models are essential tools for policymakers, scientists, and stakeholders to better understand the complexities of the climate system and make informed decisions about how to address climate change.
