Our politicians haven’t noticed that the problem may be that the world is not warming but cooling, observes Christopher Booker. For the second time in little over a year, it looks as though the world may be heading for a serious food crisis, thanks to our old friend “climate change”. In many parts of the world recently the weather has not been too brilliant for farmers. After a fearsomely cold winter, June brought heavy snowfall across large parts of western Canada and the northern states of the American Midwest. In Manitoba last week, it was -4ºC. North Dakota had its first June snow for 60 years. There was midsummer snow not just in Norway and the Cairngorms, but even in Saudi Arabia.
