In Unit 3 we learned about the carbon cycle and climate change. Carbon is everywhere on Earth and is constantly flowing between reservoirs. As we continue to increase our CO2 emissions through human activities, we are disrupting the carbon cycle creating more severe consequences.Using the data below that was obtained by a student in the 3.06 Carbon Cycle Changes lab portfolio, discuss why one carbon reservoir has changed from the pre-industrial era to today. What caused these changes?
The data obtained by the student shows a significant increase in the amount of carbon dioxide in the atmosphere from the pre-industrial era to today. This increase can be attributed to human activities such as the burning of fossil fuels, deforestation, and industrial processes.
Prior to the industrial revolution, the carbon cycle was relatively balanced, with carbon moving between the atmosphere, plants, animals, and the oceans in a natural, harmonious cycle. However, with the advent of industrialization, humans began burning large amounts of fossil fuels such as coal, oil, and natural gas for energy, transportation, and manufacturing. This process releases large quantities of CO2 into the atmosphere, disrupting the natural balance of the carbon cycle.
In addition to burning fossil fuels, deforestation has also contributed to the increase in atmospheric CO2 levels. Trees and other vegetation act as carbon sinks, absorbing CO2 from the atmosphere during photosynthesis. When forests are cut down and burned or cleared for agriculture, the stored carbon is released back into the atmosphere, further adding to the CO2 levels.
Overall, human activities have led to a significant increase in atmospheric CO2 levels, which has contributed to global warming and climate change. It is important for us to understand these changes in the carbon cycle and take steps to reduce our carbon emissions in order to mitigate the impacts of climate change.
