The recognition of shorter days hit me last night and this morning. The accumulation of the imperceptible daily shifts have hit the tipping point. We've lost 28 minutes of daylight so far. I celebrate this in the summer. In late January, I bemoan the lengthening of them.
Oddly, as I typed this, I thought that sounded like a Tip post. To complete that theme, I'd have to say something liike "heh--in a few more weeks we'll find the magnitude of the solar radiance isn't heating the inside of my car as much".
