You seem confused b.b. Sometimes in denial. Are you saying that man made atmospheric pollution has NO effect on the climate? If you are not, then to advocate letting the status quo prevail reeks of moral bankruptcy. Or are you one of those who have recognised the likely future and has just given up? Global warming is happening NOW at a faster rate by far than has ever been detected through archeological investigation. Reputable science has suggested that the rate of species extinction today is faster than the great extinctions of the dinosaur period. If humankind accepts that their actions are having climatic effects, then it follows that it has a much greater moral obligation to take action to arrest or reverse those effects than any that George Bush ever prayed to his "god" about. The measures promised by the Kyoto accord are woefully inadequate. Those being approached by the US administration are abysmal, and, frankly, cowardly.
