Good information Eugene, Thank you.
And thank you to all the others who have also put forward their input.

My take away from Coral Growth Rate as an Environmental Indicator
when used as CO2 and temperature historical data is at-least as fuzzy
as using tree ring data to determine historical CO2 and Temperature.

This is off topic for this group.
I added only to support my response.
Does Tree Ring Study Question Global Warming Projections?
