Temperature Forecasting Quiz

Just for fun, test your climate forecasting skill by printing the image of the Quiz page showing two charts, below, and draw in your 25-year forecasts. (A pdf file copy of the Mystery Temperature Chart Quiz is available here.)


When you have made your forecasts, check them against the actuals and grade them, here.


Slides used in 25 June 2012 International Symposium on Forecasting (Boston) panel session on climate forecasting. Panelists providing commentary were Leonard Smith, Richard Lindzen, and Robert Fildes.
