The two primary sources of anthropogenic carbon are fossil fuel combustion and land use changes. Indicate which are the three main carbon sinks for this anthropogenic carbon.The three primary sinks of carbon are oceans, land and vegetation, and the atmosphere. Interesting also that CEMENT application is the third biggest source of CO2e. True or False? Clearing forests to plant agricultural crops results in an increase in atmospheric carbon dioxide.True Early in the video lecture, Dr. Matsumoto talked about seasonal fluctuations in CO2 (This is very easy to see when you look at atmospheric concentrations of CO2 graphs.) What are these seasonal fluctuations due to?Photosynthesis and respiration or decomposition Dr. John Baker in the video talked about how work is ongoing on ways to improve carbon sequestration as part of agricultural practices. What is meant by the term "carbon sequestration"?Capturing of atmospheric carbon by plants, soils, and oceans. True or False. Due to fossil fuel burning, the carbon concentration in the atmosphere has NOT been constant (and actually increasing) since around 1800, about the time of the industrial revolution.True Algae and other plants play this role in the Carbon Cycle.
