“Never do that again…” UPDATE
Lord Monckton, sternly but sadly, told those who had raised their hands: “You know, from the plain and clear demonstration that I gave during my lecture, that the IPCC’s[Int’l Panel on Climate Change] statistical abuse was just that – an abuse. Yet, perhaps out of misplaced loyalty to your professor, you raised your hands in denial of the truth. Never do that again, even for the sake of appeasing authority. In science, whatever you may personally believe or wish to be so, it is the truth and only the truth that matters.”
From Lord Monckton’s Schnectady lecture, per Wattsupwiththat. Read the whole tale, it’s an interesting read.
