Question

Which are likely effects of an increase in the concentration of atmospheric carbon dioxide on both the global climate and carbon cycle?

Answer 1

This question lacks options, however, it can be answered based on general understanding. The answer is;

It leads to an increase or rise in the global atmospheric temperature, called GLOBAL WARMING.

Step-by-step explanation:

Carbon dioxide (CO2) is an atmospheric substance (gas) that has the ability to trap and emit heat. This property makes it a renowned green house gas. An increase in the amount of CO2 in the atmosphere will lead to a rise in the Earth's global temperature.

This process whereby the atmospheric temperature of the Earth increases is called GLOBAL WARMING, and it affects the climate of the world and carbon cycle of the Earth.
