They used Paine's Common Sense to justify the American Revolution.
Answer:
Dendrochronologists study tree rings to learn about past climates. Trees in temperate areas form one growth ring per year. Scientists can look at the rings and identify climate conditions during each year of the tree’s life. Scientists found long droughts in both the twelfth and thirteenth centuries. This is the same period when the Anasazi were leaving Chaco Canyon. Under normal conditions it was hard to support their villages in the harsh environment of northern New Mexico. When years of drought occurred, the densely populated Anasazi pueblos could no longer raise enough food. Other forces could have pushed the Anasazi away from Chaco as well.

What do peasant farmers do when they lost their crops?
Peasant farmers often depended on <em>subsistence agriculture</em> - this means that the farmers primarily grew crops to feed themselves and their families, rather than selling their crops for economic gain.
So, if the peasant farmers lose their crops, they will have nothing to eat. The peasants will probably go hungry and perhaps starve.
And what common pattern do we see when the masses are starving? They <em>revolt </em>! I suppose that's a bit of a stretch, but in general, the peasant class would definitely be upset at having no crops to feed themselves and their children. Such tensions will be directed at their leader or "King" who is supposed to be prepared for any disaster.
Wouldn't people think, "The leader has everything he wants and can get anything he does not have, can't he share with us?"
Anyways, that's how I would interpret this question.
Hope this helps!
