here is my intended contribution. However the page seems not to accept it.
On the contrary, we seem to know all, the debate is over etc. the scientific method has been discarded and evidence is being replaced by model predictions. I stress again, the core business of science, attempting falsification attempts, is considered a hostile act now and the perpetrators await tar and feathers. Analysing the social elements of global warming, it is astoundingly, blatantly, in conformity with all the symptoms of groupthink, formulated by Irvin Janis. And any major historic groupthink hype has almost invariably led to catastrophe.
But then again, the evidence for global warming, as it seemed so abundant in 1988 when the IPCC came into being, is disappearing slowly. The spikes in the ice cores are no longer caused by greenhouse gasses. The hockeystick is exposed as noble cause corruption. The actual temperatures refuse to go up with increasing stubbornness. Moreover, there are some serious doubts about the so called positive feedback elements so essential or tipping points and runaway climate. See: http://earth.myfastforum.org/about134.html
Yet, the confidence in the human cause is ever growing, 90% according to the last –non peer reviewed- summary for policy makers. If the confidence is inversely proportional to the evidence then one can be sure to see groupthink. But if you want to change society you can’t afford to lose global warming as driving mechanism to control the energy balance, so it must be true at all cost. Continuing this hype may however achieve the opposite of the intention of an happy Earth. The scarifying of the rain forests, for instance, to produce biofuels. It’s the hype that threatens the extinction of numerous species, not the minor climate alleviation itself, if it persists in the first place. The sooner mankind goes cold turkey on the hype the better. It’s more than time to address the real problems.
