• What Soil Actually Is: The Thin Living Skin of Land
  Soil takes centuries to make, hosts a quarter of Earth's biodiversity, holds more carbon than the atmosphere and all plants combined, and grows almost everything you eat — yet most people have never thought about it. Here is the thin living skin of the planet, horizon by horizon.
• How to Read a Weather Map — Pressure, Fronts and What the Clouds Will Do
  Synoptic charts look like scribbles until you learn four symbols. Then you can forecast the next twelve hours better than most phone apps.
