GISS ModelE is a computer model developed by the Goddard Institute for Space Studies to simulate the Earth's climate system. It helps scientists understand how various factors, such as greenhouse gas emissions and solar radiation, influence global temperatures and weather patterns. The model incorporates complex interactions between the atmosphere, oceans, land surface, and ice. Researchers use GISS ModelE to predict future climate scenarios and assess the potential impacts of climate change. By analyzing historical data and running simulations, the model provides valuable insights for policymakers and environmental scientists working to address climate-related challenges.
