By asking " an ice-free summer Arctic by 2016?" have the doom merchants finally committed themselves?

I have really had it up to here with alarmists. Vince pretends to know where the sea level in Florida will be in 50 years. They made many predictions not so long ago that failed miserably. All these people do is redraw the line, lie about previous predictions gone wrong, whine about tobacco and oil companies, and continue with their charade that they have a slightest clue what they are talking about.
