Jaxa posted the May 31, 2010 daily value for sea ice, and I was able to compute the average for the month. Because this is betting, not science, I record a ridiculous number of significant figures to enter into the script. With a bet of 11.921 million km^2, Pieter is our winner on the May average sea ice bet. Phil took second place, betting 11.921 km^2.
Many will recall that the average NH ice extent for April 2010 was rather high. May took out a huge amount of ice. The average for may is influenced both by the early high values and the later low values. In the end, it is close to the value one might have guessed if they’d just applied a linear extrapolation to available ice extent values in the JAXA record for May. Here are the plots.
If you want to see how your bet compared to other peoples, all bets are indicated below. (I edited a few who entered values like 10,130,000 etc. I figured you really meant 10.13. I didn’t know if Hal really meant to bet 1 or 10, so I left that alone. )
Results are no longer displayed to keep my site from going down!
For those who can’t get enough of betting, you can now bet on the average ice extent for June. There will be additional bets.
Hhmmm…I didn’t expect to lose the comments when I set this to draft so I could update. Thanks to those who noticed I’d calculated the May winning using June bets. Oddly enough, it was a cut and paste error. I should have checked to see that I’d changed from June to May.
