It probably won't take until we are all dead to see and feel the effects of the unnatural rise on atmospheric CO2. Indeed, we are feeling it now. Despite the few days of cold arctic temperatures, this has been a pretty warm year. In fact, the 10 warmest years on record occurred in a 12 years period from 1997 - 2008, according to NASA. This isn't an accident, nor can it be attributed to any wobble, precession or other change in the Earth's axis. Neither does the Sun's cycles correlate with the rise in temperatures. The relationship between atmospheric CO2 and global temperatures, and the relationship between man-made CO2 emissions and natural emissions and absorptions are becoming better understood, and the evidence is pointing to CO2 emissions from man made sources. If it continues to get hotter, then there will be no denying that CO2 warming is to blame.
What kchriste was talking about is the long process that locks away carbon in oil reservoirs and tar pits. It takes perhaps millions of years to convert organic matter into the oil we burn and much has been used in only a century or so. So the rate of releasing the CO2 is much, much, much, much greater than the rate that is sequestered by the Earth. What he said is absolutely true, and point sources or continuous sources are irrelevant and don't prove or disprove a thing one concerning this process. Awhile back, we had access to some data from NOAA that showed how much CO2 the Earth releases and absorbs, and how much is being released by man, and what the budget is. What we got from that is that the rise is 100% due to the activities of man. It's not that hard to understand.
