what anthropogenic activities leads to the disturbance of the carbon cycle?

Answer 1

1) Digging or pumping sequestered carbon out of the ground in the form of fossil fuels. This sequestered carbon was deposited millions of years ago and formed from enormous quantities of dead plants.

2) Burning said sequestered carbon thereby releasing it back into the atmosphere.

3) Mining of calcium carbonate rock, another sequestered form of carbon. This sequestered carbon was deposited millions of years ago and was formed from the skeletons of huge quantities of plankton.

4) Said calcium carbonate is roasted to make cement and thereby releases a large amount of CO2 into the atmosphere.

5) Large areas of forest are cut down. Much of the wood is eventually burned releasing CO2 into the atmosphere.

6) Warming of the permafrost in the Arctic is releasing large amounts of CO2 into the atmosphere.

7) The oceans are absorbing CO2 as a result of increased CO2 levels from the sources listed above. This is causing the oceans to become more acidic. CO2 when dissolved in water becomes carboxylic acid.

8) Increased CO2 levels in the atmosphere are impacting plant growth. In some cases encouraging growth and in others inhibiting growth.

9) Increased CO2 levels are causing global heating. Global heating is intern impacting weather patterns, surface temperatures, water temperatures, plant growth, and CO2 uptake or release.
