The final guesses are shown above.
In the comments of the last post, Crandles was nice enough to put a data table up. With minor corrections, that table is included below. Unfortunately, due to the lousy table support in blogger, I've simply screen captured an excel spreadsheet. Comment if you want the numbers.
Finally, here is a comparison of the aggregate guess to the Wegener Institute forecasts.
Feel free to post links to other professional forecasts in comments, and I will add them. From a statistical point of view, our 'alarmist plateau' has a statistically strange shape.
As discussed in the rules, the prize is a blog post on the topic of your choice. If you're feeling cocky, post your topic now. Otherwise, continue to trash-talk amongst yourselves. And keep watching IARC-JAXA's latest numbers. We should have a winner by the end of September.
Thanks y'all for playing, and feel free to suggest ways of over-interpreting everybody's estimates.
