Climate modeling

Definition

Climate modeling is a scientific method used to simulate and understand the Earth's climate system through mathematical representations of physical processes. These models help predict future climate conditions based on various factors like greenhouse gas emissions, land use, and solar radiation. They are crucial for assessing climate change impacts and guiding policy decisions.
