The exponential increase in carbon dioxide (CO2) concentrations around the 1860s is primarily attributed to the combustion of fossil fuels by humans. This period marks the beginning of the Industrial Revolution, during which coal, oil, and natural gas began to be widely used for energy, leading to a significant rise in CO2 emissions.
