Excluding fossil fuel combustion, how else do humans affect the carbon cycle?
Answer
Data on CO2 emissions from all sources, including cement manufacture, can be found in the Environmental Protection Agency (EPA) report “EPA Inventory (2002) of U.S. Greenhouse Gas Emissions & Sinks: 1990-2000” http://www.epa.gov/oppeoee1/globalwarming/publications/emissions/us2002/index.html, especially Chapter 3. Industrial Processes

These other sources also have CO2 emissions data and information:
Carbon Dioxide Information Analysis Center.
