Sir, - What is all the fuss about the phrase "enhanced greenhouse effect"? Unlike Myles Crowe and William Reville (September 5th and 16th), I can see nothing wrong with the word "enhanced". The Concise Oxford English Dictionary defines "enhance" as heighten, intensify (qualities, powers, value), giving its etymology as enhancer, Middle English, probably an alteration from enhaucier, Old French.
Thus, "enhanced" does not mean "made better", whatever its modern connotation may be. - Yours, etc., Dr Anthony Beese,
