Mashnich and Bashkirtsev’s 2007 Climate Wager
Solar physicists Galina Mashnich and Vladimir Bashkirtsev, of the Institute of Solar-Terrestrial Physics of the Siberian Division of the Russian Academy of Sciences, believe the climate is driven by the sun and predict global cooling will soon occur. The two scientists are so convinced that global temperatures will cool within the next decade they have placed a $10,000 wager with a UK scientist to prove their certainty. The criteria for the $10,000 bet will be to “compare global temperatures between 1998 and 2003 with those between 2012 and 2017. The loser will pay up in 2018,” according to an April 16, 2007 article in Live Science.

Here is a Nature article on the bet. The other side of the bet is James Annan.
Al Gore and the rest of the political hacks and pseudo scientist have made their money. They could care less what happens. Al Gore would not accept the bet if he was given 10 to 1 odds because he knows he is lying.
