Sat in the centrally heated school Christmas concert, I sang, like countless others, In the Bleak Midwinter, not knowing the half of it. Christina Rossettis mournful, yearning poem, later set to music by Gustav Holst, was written in 1872, but speaks of a bleak midwinter, long ago, relocating the nativity to a chill northern landscape where, Earth stood hard as iron, water like a stone.

It was a period of exceptional cold driven by chaotic internal variability within the climate system. Crops failed, food and fuel prices rose. Malnutrition and famine struck many parts of Europe. Weakened populations fell prey to disease and pestilence, themselves worsened by environmental and living conditions
