My position is that available empirical evidence in conjunction with theoretical considerations such as atmospheric transmission of visible-frequency solar radiation, infrared blackbody re-radiation and known CO2 spectral absorption points in toto to a significant causal relationship between human industrial output of CO2 and rising surface temperatures, and that this correlation is good enough to formulate models of future climate activity with a moderate degree of accuracy (assuming the algorithms and processing power are up to snuff).
However, I consider it a political priority of only tertiary importance, unworthy at this time of initiating significant policy changes to curb its effects. One reason is simply that the status quo is propounding so many undesirable policies at present that other considerations take precedence over climate change. The present administration is too incompetent and ineffectual to entrust with the responsibility. If we initiated large scale action against CC now, it would de-emphasize and exacerbate the more pressing policy issues. Another reason is that, in general, I just can't bring myself to care very much about climate change.
