claim: The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half).

evidences.article: Fossil fuel
evidences.evidence: It is estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tonnes of atmospheric carbon dioxide per year.

evidences.article: Greenhouse gas
evidences.evidence: This increase has occurred despite the uptake of more than half of the emissions by various natural "sinks" involved in the carbon cycle.
