Emissions scenarios refer to a range of possible future emissions of greenhouse gases, primarily carbon dioxide (CO2), resulting from human activities. These scenarios are used in climate change research and modeling to help understand the potential impacts of different levels of emissions on global temperatures, sea level rise, and other aspects of our changing planet.
Emissions scenarios can be based on various assumptions about future economic growth, energy use, technological advancements, and policy decisions that could influence how much CO2 is released into the atmosphere over time. By exploring different emissions scenarios, scientists can better understand the potential range of outcomes for climate change and develop strategies to mitigate its impacts.
In summary, "emissions scenarios" refer to a set of possible future greenhouse gas emission levels that could result from human activities, which are used in climate research and modeling to help predict and prepare for the consequences of different levels of emissions on our planet.
