Global warming advocates will concede that human based additions to greenhouse gasses are minimal as compared to other natural sources within the biosphere, even conceding that "land use" is a big part of the human factor, not just the burning of fossil fuels. However, they say, the addition of carbon from the burning of fossil fuels adds what ends up contributing to a "cumulative net gain" that the various natural carbon "sinks" within the biosphere cannot recycle; a cumulative and destructive build up over time caused by the burning of fossil fuels. They claim that this cumulative net gain is destructive and will cause ever greater climate change warming as we move forward. However, there are many ways in which nature recycles greenhouse gasses, (those carbon "sinks" that recycle CO2 like photosynthesis for example). Is it a "fact" that nature cannot absorb the levels of carbon emissions produced by burning fossil fuels and that the balance of greenhouse gasses has been dangerously broken? Or is that either a myth or manipulation of data combined with wishful estimations? Admittedly, it can be hard to find counter evidence within the secular, largely liberal "scientific" community to offer what the contrasting viewpoint on this might be.
