Sir, – David Robert Grimes tells us (Opinion, April 1st) that the recent cold weather was caused by global warming. I wish he and his colleagues would make up their minds. Previously we were told that our children would be lucky to ever see snow again and spring would come earlier and earlier. It appears that, to such commentators, the theory of man-made catastrophic global warming cannot be challenged by any evidence from weather, such as the last 17 years of flat global temperatures. – Yours, etc,

Sir, – The article on global warming (David Robert Grimes, Opinion, April 1st) was somewhat confusing. In particular, when he states,“Arctic ice melted at record rates last year, releasing heat energy”, one is forced to ponder. Does ice not absorb heat energy in order to melt? Perhaps this point may help to show why the “scientific consensus” is not unequivocal, as he claims! – Yours, etc,
