Very little question about warming: BUT --> is it a natural cycle?  or is it man-induced?  some combination?  if our contribution proves to be small, are we better off planning on what to do with the future (dikes, as in Holland, etc.) or do the "easy' thing and implement dramatic shifts of wealth to other countries as penalty for doing this to the planet (Cap and Trade), or, what/where does our true moral responsibility lie? Giving to corrupt regimes in ME or Africa seems to be a waste!  What do you suggest --> rationally and intelligently that truly helps the whole planet, and not a "throw money at those people over there" (i.e., not as a guilt-ridden person with little thought as to the net benefits to all parties)?
