Sure.. But in the end, we have been pursuing this ends all along. Regardless, I will happily participate.
Yes, only without properly referenced points. Hence my challenge to you in a more formalized style of debating these points.
The discussion be focused on establishing that anthropogenic sources (carbon dioxide) are a significant contributor to climatic changes... To be more specific, these sources must be significant enough such that curbing these anthropogenic sources will - absolutely - alter the climatic system in a corrective manner.
My discussion will be focused on establishing that the warming signal and many corollaries we measure is predominantly a function of an enhanced greenhouse effect.
Your position that:
I believe that the climate changes the Earth is experiencing are a part of the natural cycle that the globe has experienced for millennia. I do not support the contention that anthropogenic sources are significant enough to represent a factor that is large enough wherein curbing the CO2 output will have any real and tangible effect on redirecting the climatic systems.
will be up to you to provide evidence for. As a head's up to you, I will tell you right now that an immediate halt to our emissions of greenhouse gases will not have tangible effects for some time. It will only mean that we stabilize the global mean temperature at a value a little higher than the warming we've already experienced.
You can read more about experienced warming to date, the warming still "in the pipeline" and relevant time lags in the climate system in this paper:
Temperature increase of 21st century mitigation scenarios — PNAS
(though right now the PNAS site seems to be down for maintenance)
Obviously, you are welcome to choose any reference sources you wish, however, the credibility of those sources are fair game. As this is an area of particular interest for myself, I will question any such sources with the onus being on me to identify and highlight the flaw(s).
My sources will be scholarly, peer reviewed articles. The best system we have for ensuring results are robust, and the methodology sound.
I will ask for a defining statement from yourself. Give it some thought.
My defining statement is this: we've experienced about 0.8°C warming over the last century. The first part of the century was a mixture of anthropogenic and natural variability, while the latter half has been dominated by the anthropogenic signal. I will provide evidence from observations that confirms the expected results from an enhanced greenhouse effect. To show that the observed climactic changes are consistent, climate model results will be validated and used to show that the observations are an artifact of an enhanced greenhouse effect, and are not primarily the function of a known signal from a source of natural variability in the climate system.
We can start a new thread for this, I don't really care who leads it off. Just so we're clear, opening statements, then rebuttals to opening statements, then questions arising thereafter.
