According to my garden thermometer, last night was the coldest so far this winter: the temperature dropped to +3°C. Bearing in mind that I live 800ft above sea level in the Pennines, this is pretty remarkable: it's a month after the winter solstice, and we haven't had any frost yet, let alone snow and ice.
Last year's hot, dry summer was bad news for my garden slugs, but what we really need now is some really cold weather to kick them while they're down; the sort of cold, clear, frosty weather that hurts your lungs when you breathe in.
It's hailing outside as I type, and the Met Office is predicting a cold snap, so fingers-crossed!
Perhaps there's something in this global warming malarkey after all.
