The bet - final outcome

You may be wondering what had happened with this. As you will recall, some time ago I arranged a bet with two Russian solar scientists who had predicted that the world was going to cool down. The terms of the bet were very simple, we would compare the global mean average surface temperature between 1998-2003 and 2012-17 (according to NCDC), and if the latter period was warmer, I would win $10,000 from them, and if it was cooler, they would win the same amount. See here and here for some of the news coverage at the time.

The results were in a while ago, and of course I won easily, as the blue lines in the graph below show. It was never in much doubt, even though their choice of starting period included what was then the extraordinarily hot El Nino year of 1998. In fact the temperature in that year just barely exceeded 2012 (by less than 0.01C) and all subsequent years have been warmer as you can see from the black dashed line before. It seems unlikely any of us alive today (or indeed over the next few centuries at least) will ever see such a low temperature again.
