Global Warming: Who are the most alarmist here; deniers or alarmists ...?

... or skeptics and proponents, if you prefer.

Who are the most alarmist? ... and why?
Update: Just to be clear, I am asking about those who contribute to this (the Global Warming) section of Yahoo Answers. I'll ask a follow up question abbout the wider world later.

Also, alarmist in the sense of one who makes exaggerated or false claims to cause alarm in others, rather than one who is alarmed.
