While the exchanges between Rolf Westgard and Professor John Abraham are interesting, they do not deal with the really long-term elements of climate change. I invite them, through the opinion page, to discuss the Milankovitch cycles. These deal with three earth orbit variations, each of which has an effect on the temperature of the earth, and which occur around every 23 thousand, 41 thousand, and 100 thousand years.

Without diminishing the claims of current man-made influences on our weather, my question for the gentlemen is this: Is it possible that we are at a critical point in one or more of these cycles, and, if so, is there anything that we can do about it?
