Today’s New York Times has a lengthy front page (A1) story focusing on geoengineering “tools” to change our climate (hopefully for the better, although a devastating Snowpiercer-like scenario must surely be at the back of most people’s minds):

UTRECHT, the Netherlands — The solution to global warming, Olaf Schuiling says, lies beneath our feet.
For Dr. Schuiling, a retired geochemist, climate salvation would come in the form of olivine, a green-tinted mineral found in abundance around the world. When exposed to the elements, it slowly takes carbon dioxide from the atmosphere.
Olivine has been doing this naturally for billions of years, but Dr. Schuiling wants to speed up the process by spreading it on fields and beaches and using it for dikes, pathways, even sandboxes. Sprinkle enough of the crushed rock around, he says, and it will eventually remove enough CO2 to slow the rise in global temperatures.
“Let the earth help us to save the earth,” said Dr.
