A Guide to the Earth for the Layperson
The SciTechDaily website had an interesting article (28 May 2026) that summarized an international study about how climate change is affecting global sea level rise. The team included researchers from the Institute of Atmospheric...
It was early in the 1960s and my family had recently relocated from Nebraska to the Los Angeles Basin. Those were scary times! The Soviets were threatening to install nuclear missiles in Cuba, and...
Earth Day has always held a special place in my heart and memory. I was an undergraduate in Southern California for the first one, and was involved with the construction of eighty-eight geodesic domes...

I got a question from Jane who, while reading Marker Bed, became intrigued by the reference to quartz sand on page 29 of the print versions. (By the way, if you have not yet...

I’ve had a couple requests to give a few more examples of what a geological marker bed (a.k.a. marker horizon) actually is, and more fully explain why I chose Marker Bed as the title...
In their continuing efforts to dismantle the United States and remove it from its traditional place as a leader in scientific research and understanding, the current administration is now taking aim at the National...
