"Certainly plate tectonics over geologic time produces the plate movements responsible for large scale climate change. The collision of the Indian Plate with the Eurasian Plate is responsible for the Himilayan range which combined with the monsoon currents give us the most massive carbon sink and, most likely, the low CO2 levels that contributed to the most recent ice ages. What accounts for near term climate change? We are slowly and acrimoniously learning."

Well said! My knowledge is only from technical work including hobbies (e.g., open source equipment) and a recent interest in what broader physical, political and economic changes might be ahead. I'm not an engineer.

I am just a hobbyist but spent some 30 years in one or another jobs in mining (about 12 years as a day’s pay miner and the rest in supervision and middle management - personnel). From the time I was growing up in a mining town, I’ve been fascinated by geology, mineralogy and in the last two decades, plate tectonic theory). It’s better than a football game to me and things are being discovered or contradicted at dizzying pace.
