By default, En-ROADS includes the economic impact of climate change in the Baseline Scenario and Current Scenario.
Controls to modify the damage function are located under Simulation > Assumptions > Economy: Economic impact of climate change. Click the “Climate change slows economic growth” switch to turn the damage function off or on in the Current Scenario.
Note that changes made to the Assumptions in En-ROADS only affect the Current Scenario, not the Baseline Scenario. The Baseline Scenario will still include the default Burke 2018 damage function, even if the damage function is turned off or a different one is selected for the Current Scenario.
