The “New Scientist” is a left-leaning eco-friendly publication. For them to admit even a bit that CO2 is not this generation’s chicken-little pollutant shows progress in having the truth reach a closed-mind audience. At some point they will have to conclude that they have bet on the wrong science and will have to admit that AGW skeptics were correct.
They will never admit that. When the time comes, and they can no longer hold the fort, they will simply stuff the whole issue down the memory hole and, like the mad hatter's teaparty, just move on to the next place where they can create a whole new mess out of nothing.
