Some of the iconic winter landscapes by Pieter Bruegel the Elder are more than just fine examples of sixteenth-century Dutch art. Paintings such as Bruegel’s Hunters in the Snow (1565) also serve as vivid evidence for the ‘Little Ice Age’, a period of cold climate conditions and glacier advances in Europe and elsewhere that lasted from the late Middle Ages until the nineteenth century.

 

There has been quite some debate over the years about the precise onset and the physical causes of this extended cold spell, with one school of thought favouring low solar activity during the ‘Maunder Minimum’ and another the cooling effect of big volcanic eruptions.

 

A paper published today in Geophysical Research Letters may put the solar-trigger hypothesis at rest. Gifford Miller of the University of Colorado in Boulder and his colleagues suggest that the Little Ice Age began abruptly between 1275 and 1300 AD following four large sulfur-rich explosive eruptions, most likely in the tropics, over a mere 50-year period.
