Surely, it is well accepted by global warming aficionados and sceptics that there has been no overall global temperature increase over the past ten years. A letter in last week's Nature predicted this trend would persist over the next two decades. Is this article really up to date?

As the HadCET series shows, the ten-year mean has been steadily increasing for more than two decades now, and currently stands at one degree above the average temperature observed in the second half of the 20th century. British hop-growers, at least, appear to have cause to be worried.
