working models for energy conservation are:- * * * * *
Some working models on climate change include the Earth System Models (ESMs), which simulate interactions between atmosphere, oceans, land, and ice; Integrated Assessment Models (IAMs), which combine climate models with economic models to project impacts and policy solutions; and Global Circulation Models (GCMs), which simulate climate patterns and predict future climate scenarios based on different emission scenarios. These models help scientists and policymakers understand the complex dynamics of climate change and inform decisions to mitigate its effects.
