Between 2005-2011, several public bets were made about climate change, specifically about the rate of global warming.



Typically, on one side is someone who broadly agrees with the Intergovernmental Panel on Climate Change i.e. that global warming is real, caused by human activity (e.g. fossil fuel burning) and that things will get worse if we carry on as we are.



On the other side is what we might politely call a contrarian, who broadly disagrees with the IPCC. Typically, their view is that the world is warming less than the IPCC view, or not at all, or is about to start cooling.



Just for fun, I've produced a scoreboard of recorded climate bets between 'warmists' and 'coolists' (for want of some better names). It shows all the bets I can find where terms were agreed by both parties and made public - in chronological order of when the bet was agreed.



The warmists are clearly winning:
