NASA | Ask a Climate Scientist: CO2 and Temperature

The video discusses the relationship between CO2 and temperature, highlighting a shift from preindustrial times, where temperature changes drove CO2 levels, to the postindustrial era, where CO2 levels are driving temperature changes. This shift represents a fundamental change in Earth's processes, raising concerns about the lack of natural restraints on temperature increases due to rising CO2 levels.

In the preindustrial age, what was the relationship between temperature and CO2 levels?

• CO2 levels decreased as temperature increased.

• CO2 levels and temperature were unrelated.

• Temperature changes led to CO2 level changes.

• CO2 levels led to temperature changes.

What is the main difference in CO2 and temperature dynamics between the preindustrial and post-industrial ages?

• There is no difference between the two ages.

• In the preindustrial age, temperature changes led to CO2 level changes, while in the post-industrial age, CO2 levels lead to temperature changes.

• In the preindustrial age, CO2 levels led to temperature changes, while in the post-industrial age, temperature changes led to CO2 level changes.

• In both ages, CO2 levels led to temperature changes.

What does the shift in CO2 and temperature dynamics indicate?

• A completely different physical and biological process.

• A continuation of the preindustrial process.

• A decrease in the Earth's radiation balance.

• No change in the Earth's processes.

What is the scientific community's main concern regarding the post-industrial CO2 and temperature relationship?

• The decrease in CO2 levels.

• The increase in temperature leading to a decrease in CO2.

• The stability of the Earth's radiation balance.

• The lack of understanding of the new process and its consequences.

Why is the scientific community worried about the continued increase in temperature?

• Because temperature is decreasing.

• Due to the increase in the Earth's radiation balance.

• Due to the lack of a restraining force on CO2 emissions.

• Because of the decrease in CO2 levels.
