There is much heat in the blogosphere debates between those who believe that we are warming the planet, and those who are highly skeptical of such claims. I will put my cards on the table right now, and say that I think we are warming the planet. There is a lot of mistrust between the warring factions. People like me are referred to as AGW alarmists, while people on the other side are regularly derided as deniers. So to start with, I'd like to take some heat out of the debate by giving nicknames to the combatants. Those on my side will be referred to as "hotties", while the other side will be referred to as "frosties".
