"The salient aspects to the issue are, is man causing it, will the affects be good or bad or neutral, and what can or should be done about it."
I have specifically stated that the cause of the CO2 induced global warming may indeed be natural sources that we can do nothing about (repeatedly!); or, as evidence suggests, mankind's vastly increased use of combustion for energy since the 18th century may be the cause.

If the increase in atmospheric CO2 is man-made or mankind is only a significant contributer, then we would be foolish not to attempt to address it. An analogy: if my house is on fire, I should do all I can to save it whether it's arson, accident or the result of wildfire.
Climatic changes are being demonstrated as we speak. The permafrost is thawing at rates exceeding history and emitting CO2 in a divergent cycle; polar ice caps and glaciers are melting and the land beneath is rebounding under reduced loading, both contribute to rising sea levels; the chemistry of the worlds oceans is changing, acidifying and average temperature rising in the planet's major heat sink.
Hydrocarbons, other fuels are becoming obsolescent. That could be a natural impetus to other energy sources and reduction in human CO2 emissions. Or humankind could continue to screw the pooch in India, China and America's electric cars etc. might just increase pollution.
First, recognize and admit the problem- our habitat, our house is burning, whether you, I or nobody started the fire. At least try to save it.
