Why was there an increase of atmospheric carbon dioxide levels in the late-18th century?

Answer 1

There are several factors that contributed to the increase in atmospheric carbon dioxide (CO2) levels during the late 18th century:

1. Industrial Revolution: The late 18th century marked the beginning of the Industrial Revolution, a period characterized by the rapid industrialization and technological advancements. Burning of fossil fuels, such as coal and oil, for various industries including factories, transportation, and power generation, released significant amounts of CO2 into the atmosphere, leading to the rise in atmospheric CO2 levels.

2. Deforestation: Expansion of industrial activities required large amounts of raw materials, including timber for building and fuel. As a result, extensive deforestation occurred globally to meet these demands. Trees play a crucial role in absorbing CO2 through photosynthesis, so the reduced capacity of forests to absorb CO2 resulted in higher atmospheric levels.

3. Agriculture and Land Use Changes: The conversion of forests and grasslands into agricultural areas also contributed to the increase in atmospheric CO2 levels. Land clearing for farming and livestock led to the release of CO2 stored in trees, plants, and soil.

4. Population Growth: The global population experienced significant growth during the 18th century. With more people, there was an increased demand for food, housing, and energy, all of which led to greater CO2 emissions.

5. Natural Carbon Cycle: It is important to note that natural processes also contribute to the carbon cycle. While human activities were the primary drivers of the CO2 increase during the late 18th century, natural sources like volcanic eruptions and natural decay also play a role in releasing CO2 into the atmosphere.

Overall, the combination of industrialization, deforestation, land use changes, population growth, and natural carbon cycle processes led to an increase in atmospheric CO2 levels in the late 18th century.
