Balance emissions and carbon sinks to see how atmospheric CO₂ changes over three decades.
This is a simplified educational model. Values update from the equations described in Model assumptions & science.
This browser-based systems simulation helps you balance emissions and carbon sinks to see how atmospheric CO₂ changes over three decades. Designed for Grades 6–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.
Explore Emissions, carbon sinks, atmosphere, net zero by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
A typical investigation takes 8–14 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Balance emissions and carbon sinks to see how atmospheric CO₂ changes over three decades. The main ideas are Emissions, carbon sinks, atmosphere, net zero.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 8–14 min. You can repeat it to compare more variables or improve your explanation.
