A paper published today in The Holocene finds that higher temperatures during the 19th century were associated with higher crop yields and lower prices.
The paper also finds The Little Ice Age increased climatic risks to agriculture and that with increasing globalization, there has been “a weakening influence of prevailing weather on crop prices.”



The Little Ice Age also coincides with the abundance of witch trials in the “early Modern” period: en.wikipedia.org/wiki/Witch_trials_in_the_Early_Modern_period
The witch trials have been linked with hallucinations associated with the consumption of rye grain contaminated with ergot (a fungus that produces lysergic acid derivatives like LSD). en.wikipedia.org/wiki/Ergot
The ergot fungus itself thrives in the cool, damp conditions that were more common during the LIA.
This means accusations of witchcraft should qualify as resulting from a ‘climatic risk to agriculture.’
