And more.... this is actually a wholly different topic.... but very important climate cycles:
"Using a coupled lithium-carbon model, we show that initiation of the glaciation was likely caused by declining CO2 degassing, which triggered abrupt global cooling, and much lower weathering rates. This lower CO2 drawdown during the glaciation allowed climatic recovery and deglaciation. Combined, the data and model provide support from the geological record for the operation of the weathering thermostat."

This says, in babe terminology, that carbonic acid in rain can dissolve common rocks..... a process that decreases atmospheric CO2 and even oceanic CO2 content. The low CO2 starts the ice ages..... and cools everything off.... and then CO2 levels spring back and things start to warm up.
The system as a whole stabilizes and/or regulates climate like a "thermostat" of global proportions.
ah ha.
How many "Global Thermostat Deniers" do we have to send to re-education camps?
and yah yah. Trump doesn't care that much, so you're all safe.
And anyway.... I was looking for a way to objectively measure long-cycle, geologic time-scale cycles, of our sun's solar wind by evidence left here on earth.
basic hypothesis…. The sun is important, maybe most important, in earth climate changes....
more to come.
