It was officially 100° in Boston on Tuesday, which may not sound like that big of a deal to people who live in warmer parts of the country, but it has only happened twice in the last decade and only a handful of times in the last 100 years or so.
Tuesday also happened to be the point of Earth’s aphelion — the time of year when the planet is closest to the Sun — but this National Geographic article explains that the heat wave and the aphelion really have nothing to do with one another.
