Must admit moondoong I know where you are coming from. There have been periods of global warming in the past according to the same scientists and global cooling i.e. an ice age - we weren't there then so why did it happen? Could it all be natural afterall.
I must admit that is the problem with scientists everything is theory no proof but they want to continue getting their grants extended and they also want those nice pay checks from big buisness. Sorry guys there is no proof as moondoong says it's all just speculation.
