Of all the hot air blown out by eco-alarmists, their maddest claim, the one least founded in truth, is that they are objective. That their fuel is facts and facts alone. That their guiding light is science — pure, unsullied science — rather than grubby politics. That where we, the dim, denying public, are beholden to all sorts of agendas, they, these climate seers, these wise modellers of humanity’s self-induced future doom, are motored by pure rationalism, by a slavish devotion to truth.
