An optimal control model of global warming is presented and analyzed. The model has two state variables, representing the anthropogenic concentration of greenhouse gases in the atmosphere and the temperature increase due to the greenhouse gas concentration. The state equation for greenhouse gas...

The Integrated Assessment Model (IAM) has extensively treated the adverse effects of climatechange and the appropriate mitigation policy. We extend such a model to include optimalpolicies for mitigation, adaptation and infrastructure investment studying the dynamics of thetransition to a low...
