I am working on an over/under wager of the type "sea level rise by the year 2040" -- I'd like all wagers resolved in my lifetime so I'm not willing to go beyond 2040 with any wager (I'm 64 now). I'll be setting the line soon enough, and you can find it at my climate website.

If you're interested, you can see how I gather some of the information on setting my lines here:

Most climate folks are willing to bet that things will get considerably f&%ier much faster than I think they will. But I still want a sense of what odds will give me an edge.
