[Climate Change While we can physically measure the current levels of carbon dioxide, to estimate future concentrations, we have to employ computer models. On the graph below, we can see the marked increase in CO2 since the industrial revolution. This includes the observed CO2 concentration for 2018 and two predictive points based on a low-emissions and high-emissions model. If you were creating a model to estimate future CO2 concentrations, which of the following would you consider?

Real-world systems are often complex and are where natural and anthropogenic influences interact. The carbon cycle is one such system. There are processes, both human-made and natural, that release carbon into the atmosphere. There are processes in which carbon is absorbed from the atmosphere. On the image below, select the processes that absorb carbon dioxide from the atmosphere.
