So what's realistically going to happen with the climate in 5, 10, 20, and 50 years? I don't want any kneejerk denialists or doomsday cultists, I want people who have at least done some research to make conclusions without emotional presumptions.

My major concern is melting permafrost and ice caps setting off a cascading reaction. It seems inevitable that once all the arctic ice melts the effect of additional warming will be a lot more significant degree for degree.

Should a normal person worry? Will the stock market crash once people realize infinite growth is impossible? Will there be civil unrest? Climate migrations? What will be the major consequences, and what should the average person do, if anything?
