A climate model is a scientific tool used to simulate and understand the Earth's climate system. It uses mathematical equations to represent the interactions between the atmosphere, oceans, land surface, and ice. By inputting various data, such as greenhouse gas levels and solar radiation, these models can predict future climate conditions and assess the potential impacts of climate change. Researchers use different types of climate models, including global climate models (GCMs) and regional climate models (RCMs), to analyze specific areas or global trends. These models help scientists, policymakers, and communities make informed decisions about climate adaptation and mitigation strategies.
