Toby Pillatt is right. Weather is important. Weather is important every day, as is evident from almost every news broadcast we watch or hear. This is not only true for extreme weather situations – which currently abound in the news – but for ordinary weather conditions at any time. The importance is quite clearly reflected in the numerous weather channels and weather websites and the weather forecast at the end of every news programme. Despite the ‘benefits of civilization’ which today make us often independent of outside influences, many simple daily decisions are still based on the current weather situation. Weather is our first and most immediate environmental experience. It was no different in the past. On the contrary, weather-based decisions were much more important historically than at present, both for individuals and for entire societies. No doubt, then, weather should be of concern also for historical studies. Hence Toby Pillat is right. He is also correct in stating that by involving a palaeo-weather perspective we can add much to our understanding about how past societies operated.
