From William Connolley
Kevin Mayfield manages to make two errors in one short letter (5 March, p 32). The second (confusing weather with climate) is commonplace. The first (believing that 30 years ago an ice age was predicted) is less common but just as wrong. See: www.realclimate.org/index.php?p=94 for a readable explanation or www.wmconnolley.org.uk/sci/iceage/ for more detail.
