* You may have noticed that while Bellamy’s source claimed that 55 per cent of 625 glaciers are advancing, Bellamy claimed that 555 of them – or 89 per cent – are advancing. This figure seems to have existed nowhere else. But on the standard English keyboard, ‘5’ and ‘%’ occupy the same key. If you try to hit ‘%’, but fail to press shift, you get 555, instead of 55%. This is the only explanation I can produce for his figure. When I challenged him, he admitted that there had been ‘a glitch of the electronics’.²⁰
