When the problem is "real", it will be too late for solutions. We need to do something right now. Besides, I'd argue the problem is starting to be "real" right now. California, Australia, Siberia and Greece were on fire this year, Germany had historic floods and the East Coast keeps getting devastated by hurricanes.

I also disagree with the tactic of shifting responsibility to the individual to avoid doing anything where it actually matters. My individual contributions to climate change are negligible, this is a collective issue. We need to get industry and corporations in check and the only way we can do that is with heavy regulation.
