Scenario modeling

Definition

Scenario modeling is a technique used to predict and analyze the potential impacts of different variables on future outcomes, particularly in relation to climate change and environmental conditions. By creating various scenarios based on different assumptions about greenhouse gas emissions, technological advancements, and societal responses, this method helps researchers and policymakers understand how changes in atmospheric absorption and the greenhouse effect could influence global warming and climate patterns.
