The world is warming and rapidily, it is clear, the only debate is if CO2 from man is to blame. All the evidence is that it CO2 has disturbed the balance to a strong and accelerated warming, the mechanism is clear, proven in laboratory settings, is amplified by water vapour, amplified by positive feedback loops, primitive models from 1989 are proving extremely accurate and rate of rise of temp is rising rapidly, ice is melting, weather extrenes more common, droughts spreading, spings earier, etc,etc,etc and all we get is old arguements propigated by oil company funded research which don't hold up against any close examination at all.

water vapor amplifying co2?? If that is what the model is designed around, GIGO. That's like saying that little flea's weight is amplified because it's on an elephant's butt.
As for arguments, it isn't their age or their source, it's their accuracy that count.
As for our spring, it's a bit late - guess that means time for the coming ice age to be in vogue again.
