“I've been a "citizen scientist" for the Community Collective Rain, Hail and Snow Network (CoCoRaHS) for about four years now, with about 900 reports sent in from every time of year and sort of weather. I cannot say enough about how good it feels to help collect relevant climate data. Just before the summer solstice recently, CoCoRaHS, a volunteer organization, celebrated its 25th anniversary. My, how time flies.”

“In the early 1900s, the railroad leading to the coastal settlement of Luderitz in German South West Africa… was perpetually assaulted by the sands of the Namib Desert. Workers constantly had to shovel sand drifts off the rails. In April, 1908, a Black railroad worker named Zacharias Lewala found a perfectly clear stone… It was the first of the diamonds which would within four short years become millions of carats of harvested there annually.”
