Betting on global cooling

Here is an amusing story (via Drudge) about global warming.

Two climate change sceptics, who believe the dangers of global warming are overstated, have put their money where their mouth is and bet $10,000 that the planet will cool over the next decade.
The Russian solar physicists Galina Mashnich and Vladimir Bashkirtsev have agreed the wager with a British climate expert, James Annan.
The pair, based in Irkutsk, at the Institute of Solar-Terrestrial Physics, believe that global temperatures are driven more by changes in the sun's activity than by the emission of greenhouse gases. They say the Earth warms and cools in response to changes in the number and size of sunspots. Most mainstream scientists dismiss the idea, but as the sun is expected to enter a less active phase over the next few decades the Russian duo are confident they will see a drop in global temperatures.

I guess only time will tell. I should note that even if these Russian scientists are wrong, ie. global temperatures do go up, that does not mean the change is caused by human activity, and even if it was caused by human activity, the Kyoto Protocol clearly is totally useless in addressing the human contribution to the problem.
