Global Cooling Is Impacting Agriculture

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 -4ÂșC. 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. At least in the southern hemisphere it is winter, but snowfalls in New Zealand and Australia have been abnormal. There have been frosts in Brazil, elsewhere in South America they have had prolonged droughts, while in China they have had to cope with abnormal rain and freak hailstorms, which in one province killed 20 people. There are obviously various reasons for this concern as to whether the world can continue to feed itself, but one of them is undoubtedly the downturn in world temperatures, which has brought more cold and snow since 2007 than we have known for decades. Three factors are vital to crops: the light and warmth of the sun, adequate rainfall and the carbon dioxide they need for photosynthesis. As we are constantly reminded, we still have plenty of that nasty, polluting CO2, which the politicians are so keen to get rid of. But there is not much they can do about the sunshine or the rainfall...Telegraph
