I am baffled by the curious letter from Professor Reg Moores (November 29).

What he appears to be saying is that cancer and other serious diseases are not caused by global warming but by the ice age which began in the 19th Century.

This ice age is destroying our food, he says, and money "is hiding the facts".

I wasn't aware that anybody had ever attributed cancer and the other diseases to global warming. I wasn't aware that there had been an ice age for the last two centuries.

I don't know in which discipline Reg Moores is a professor - climatology, medical science or Punch and Judy - but his claims on this occasion leave me scratching my head.
