Inquiry for Spencer Glendon, Probable Futures

Greetings at one of the two most extreme moments of the year, the June solstice. The Northern Hemisphere is bathed in sunlight and the Southern Hemisphere is as dark as it gets. The center of the sun is directly in line with the Tropic of Cancer, 23.44° north of the equator, as this letter leaves one server on its way to many more and eventually, perhaps a second or two later, to your device.

“Just right” where you live
The most intense solar radiation is always between the two tropics, while the Arctic and Antarctic oscillate between light and dark. These are profoundly important sections of the Earth, but this letter is addressed almost exclusively to people in the bands in between. Probable Futures is just getting started, but we are fortunate to have interested people on every populated continent.
