the past thousand years. Between 900 and 1300 temperatures over northern Europe
were positively balmy. Erik the Red鈥檚 colonists fattened cows in Greenland,
while the French tried to embargo England鈥檚 fine wines.
But by 1315, a succession of poor summers and harsh winters created Europe鈥檚
worst-ever famine. The Greenlanders ate their cows right down to the hooves.
Fagan analyses a period of violent climate swings in The Little Ice Age. And
he is just as at home explaining the mechanics of the North Atlantic Oscillation
and its flips, changing the course of warm currents and affecting the weather,
as he is with their dire human consequences But this was no prolonged freeze,
periods of decimating cold alternated with torrid summers and frequent floods.
Using sources as diverse as tree-rings, wine yields, monastic tithes, ice cores
and cloud cover percentages in five centuries of paintings, Fagan shows in this
wonderful book how vulnerable human society is to climatic zigzags.
Rapid climate change is nothing new.
