The U.S. Environmental Protection Agency Inventory of U.S. Greenhouse Gas Emissions and Sinks (2005) has the CO2 lifetime listed as 5 - 200 years, for example [1].

The evidence that the current rises of both CO2 and CH4 are anthropogenic are overwhelming (from isotope data, O2 data, ocean data, emission inventories etc.).
