Figure 2.20: Global Atmospheric Concentration of Carbon Dioxide and Global Temperatures (1750–2019)
This figure presents a graph showing the trends in global atmospheric carbon dioxide concentration and global temperatures from 1750 to 2019. It is important to note that while the title refers to 'global temperatures,' the data used for the temperature trend specifically represents the average for the Northern Hemisphere. The graph is used to illustrate the relationship between the increasing stock of atmospheric CO2 and rising temperatures.

A new global policy successfully reduces the annual rate of human-caused CO2 emissions by 30% from its peak. Assuming this new, lower rate of emissions is maintained and is still greater than the rate at which natural systems can remove CO2 from the atmosphere, what is the most likely consequence for the planet's climate?
True or False: If the annual rate of CO2 emissions from human activities were to stop increasing and remain constant at today's high levels, the total amount of CO2 in the atmosphere would also stop increasing, leading to a stabilization of global temperatures.

Explaining the Dynamics of Atmospheric CO2 and Global Temperature
Match each concept to the statement that accurately describes its relationship to global warming.
For global temperatures to stop rising, the annual rate of CO2 emissions must be reduced until it equals the rate at which CO2 is naturally removed from the atmosphere. For temperatures to begin to fall, the total accumulated amount of atmospheric CO2, also known as the CO2 ______, must decrease.
A hypothetical country undergoes a series of environmental and policy changes over several decades. Based on the relationship between atmospheric carbon dioxide (CO2) and global temperature, arrange the following events in the most likely chronological and causal order.

A graph displays two trends from 1750 to 2019. The first trend, representing the atmospheric concentration of carbon dioxide, is relatively stable until the mid-19th century, after which it begins to rise, with the rate of increase accelerating sharply in the 20th century. The second trend, representing the average temperature in the Northern Hemisphere, shows a similar pattern: relative stability for the first century, followed by a consistent and increasingly rapid upward trend. Based on the patterns described, which of the following statements provides the most accurate analysis of the relationship between the two variables?
Evaluating a Policy Conclusion on Climate Data
Consider a graph that plots two variables from 1750 to 2019: (1) the global atmospheric concentration of carbon dioxide and (2) the average temperature for the Northern Hemisphere. A policy analyst makes the following claim based solely on this graph: 'This graph provides definitive proof that the average global temperature has risen as a direct result of the increase in atmospheric carbon dioxide.' Is the analyst's claim a fully accurate and justified conclusion based only on the information described?

Critiquing a Climate Change Argument
A graph displays two trends from 1750 to 2019: the global atmospheric concentration of carbon dioxide and the average temperature for the Northern Hemisphere. Both variables are relatively stable until the mid-19th century, after which they begin to rise at an accelerating rate. Match each analytical term below to its correct interpretation based on this graph.
Critiquing a Conclusion from Graphical Data
A graph from 1750-2019 shows that as the atmospheric concentration of carbon dioxide increased, so did the average temperature in the Northern Hemisphere, with both trends accelerating over time. Imagine a new global policy is enacted that successfully reduces the rate of increase of atmospheric CO2 to half of what it was in the final years of the graph. Based on the relationship shown, what is the most likely immediate impact on the total atmospheric concentration of CO2?
A graph shows that from 1750 to 2019, the total atmospheric concentration (stock) of carbon dioxide and average temperatures have risen together, with the rise accelerating over time. Based on the underlying principle that the stock determines temperature, if the annual addition (flow) of CO2 into the atmosphere were to suddenly drop to zero, the total atmospheric stock of CO2 would also immediately begin to fall, causing temperatures to quickly decline.
