The tenet for Eric Alexander’s argument for man-made climate change (Letters, Aug 1) appears to be exactly the same as that used to delude Western Europe into belief in a Geocentric Universe. It took 1,800 years to dispel that myth, to wrest control from the charlatans and enter the Renaissance, the reason civilisation was able to progress technically to where it is today. Regression to belief in myths, so prevalent today, for the benefit of the current bunch of charlatans does not bode well for the future of humanity. — Mr P.D. Somerville, High Wycombe
