I find climate projections to be very similar to financial projections of startups. A typical chart will show hockey stick like growth (temp vs revenue) over a long period of time. Since both groups need to prove that they will have an impact in order to get funding they are motivated to show the most drastic/promising future. As a statistician I tend to discount any long term projections for complex systems because I know that there are too many factors that will influence the results.
