I do believe anthropogenic activity has changed climate in the context of historical climate change. We are still at the end of an ice age. There was a mile of ice over NYC just 10,000 years ago. Man had nothing to do with that and I suspect that if humanity is wiped out by its own avarice, it will change again.
Having said that, I just got back from a trip to Shanghai and have been recently been to Beijing. The devastation to the air, water and land done by man is unmistakable. The change in those climates is unmistakable. The compounded insult to the environment from every aspect of human activity is unmistakable and only we can change our behavior, or for sure, the environmental change will dictate it.
