What you fail to acknowledge is that climate change happens for reasons beyond our control.
Well, that is ALSO possible. Natural disasters or phenomenon can also effect Climate change. However, since Humans have only recently begin to engage in activity that really can have negative impact, there is a new force at work now that was previously not present.
So, this is a NEW reality and must be acknowledged. Real damage can be done by people and it is well within our control to exacerbate it or prevent it.
