I will certainly admit to being one of those unconvinced by the claims that we are undergoing catastrophic warming. It is the case, as Paul Shaw says (Letters, November 29), that some glaciers are melting. It is also the case that some are growing and some just sitting there. That there are currently glaciers in the Alps blocking places which, in Roman times, were used as passes, means that even the glacier evidence shows nothing outwith historical experience.
