 Hot dinners We’re coming to the end of the hottest year on record, and the coming years could be even warmer. A hotter climate will affect crop yields, unless ways of boosting them can be found. “Food security is my biggest worry about climate change,” says the environmental scientist Hannah Ritchie. We’re “in a race: can innovation and agricultural productivity keep pace with a changing climate?” So far, the answer is yes, she says. “Temperatures might have broken records, but so has crop production.” The U.S. Department of Agriculture predicts that the 2023/24 marketing year will see record crops. Droughts and floods have hit local production, but even that has less impact than it would have done in the past, as when a 19th century El Nińo caused starvation. “We won’t have tens of millions dying from famine this time,” says Ritchie. “Modern agriculture, global supply chains, and political structures mean we’re much more resilient to extreme events.” Devil in the details In 638, the small town of Widecombe in Devon, southwest England, was struck by a storm. Presumably that was not in itself an entirely unusual event, but this one was, according to surviving accounts, notable, in that several churchgoers “were violently killed by what was either the temporary suspension of normal laws of physics or possibly the Devil.” The scientist and medievalist Alexander Zawacki cites two contemporary accounts. Lightning struck the church and bounced around inside “as if it were with a great Cannon bullet.” It “strook off all the hinder part” of one man’s head, and “the braines fell backward intire,” which sounds unpleasant, although the front of his head was so untouched they thought him merely sleeping. Another three were killed. Stories at the time described it as an act of God, but soon stories spread that “the Devil had come to Widecombe to claim the souls of one of its parishioners — which, honestly, maybe.” Sprinting slowly to the finish The anonymous blogger Tracing Woodgrains once wrote a blog post titled “Speedrunning College: My plan to get a Bachelor’s degree in a year.” Now he revisits it. “It would be wiser, in many ways, for me to avoid writing this article,” he sighs, because four years later — the normal amount of time it takes to complete college in the U.S. — he has only just got his degree. The speedrunning plan was an attempt to short-circuit his own problem with procrastination. He had struggled with it during high school, but found that — when given clear goals — it disappeared: He was “diligent, focused, and capable” as a Mormon missionary and sailed through military basic training. But then, a few months in, the procrastination began again. “I am a man at war with my own mind,” he writes. Only the looming disaster of flunking out gave him focus. His advice to educators wishing to help others struggling with procrastination: Enforce “tight deadlines, supervision, and other tools of rigor.” |
