Anthony Caughey (The Australian, Letters, 16/1) inadvertently gives climate science a boost by articulating the alternative theory: that the scientific consensus is the result of “decades of educational indoctrination”. It would be entertaining to hear how this posited infiltration of the world’s academies was organised and funded, by whom and for what evil purpose, but I suspect that Occam’s razor would favour the simpler hypothesis: the scientists have it right.
