If it alters, then you get new averages and a climate change. > You guys ready to give in yet and admit that climate is chaotic? > Because really the weight of scientific opinion is against you. Tim Palmer is not scientific opinion. Gavin Schmidt takes the opposite view. But IMHO Tim not Gavin is correct. If climate is chaotic then it is deterministic, so we can predict what will happen, but not with the precision of weather. But we do not need that precision for climate. We don't need to know what the weather in London will be in four days time. We need to know what the climate will be in Europe in 10/100 years time. The orbits of the planets are chaotic, but we can still predict there positions a hundred years hence.
