And not before time, you might say. Sea ice this year reached a new record minimum in the Arctic (though not in the Antarctic, which begins to look wind-driven. And before you think the two trends might be opposite-and-nearly equal, look at Tamino’s convenient analysis which I can never find). Which means I lost some of my bets. Now, what exactly was I betting on?
Crandles helpfully points me at Betting on sea ice: $10,000 although the $10k doesn’t fall due until 2016. But in the comments (the one from 2011/07/04, since perma-linking here remains invisible to all but me) we agreed:
we are betting £x that either 2011, 2012 or 2013 will beat the minimum extent record of 2007, based on daily IJIS SIE numbers (which makes it more fun), but the record has to be confirmed by the monthly NSIDC extent number.
where x=100. Neven had the same bet (recorded in Sea ice, part 2, but for E50. In defence of my own tattered reputation I’ll point out that I said at the time So to re-visit some earlier stuff: I said the chance of something beating 2007 and setting a new record low within the next 3 years (including 2011) seems quite good. So I’m not betting on that in response to Neven’s offer. But if I switch to the not-so-safe green line I think that just about fits the error bounds and only took it on for the thrills. But now I’ve lost so N and C need to email me their bank account details or some other such method of xfer (paypal would be convenient for me).
And what of the future? Who knows. Closer inspection of this post will reveal traces of me intending to talk about the actual ice, but I think I’ll postpone that for a while.
[Update: per agreement in the comments (see! I can do permalinks), Neven and I are converting our bet to double-or quits: “either 2013, 2014 or 2015 will beat the minimum extent record of 2012, based on daily IJIS SIE numbers (which makes it more fun), but the record has to be confirmed by the monthly NSIDC extent number” for E100.]
