Of course the future is uncertain - that goes without saying. Saying so is just rhetoric.
Indeed humans have an impact on conditions and life on Earth - many of them negative. But there is no convincing proof that completely overpowering and screwing up the global climate is one of them.
The problem as I see it now is that we are spending so much time, money and effort on demonizing and fighting a harmless trace gas that real harmful problems are being overlooked.
