The current and future amount of carbon (in the form of carbon dioxide) in the atmosphere and the hydrosphere is what currently concerns and occupies many people.
I am looking for a big picture of the net fluxes between different carriers of carbon that gives a good idea where the anthropogenic CO2 emissions (and other greenhouse gases) actually did come from (compared to e.g. 1500, 1800, 1900, 1950 and 2000).
So I am looking for rough (and possibly estimated) numbers like these - optimally in an overview, so the numbers sum up to 100:
p1% by fossil fuel burning
p2% from the natural biosphere (which decreased), esp. deforestation
p3% from cultivated biosphere (which increased), incl. methane emissions from cattle
p4% from industrial abiotic chemical processes, e.g. cement production
pk% other important sources with pk > 1%?
