Working on my point paper of the https://www.physicsforums.com/showthread.php?t=2974 and I need to address the runaway greenhouse effect ideas. Now we have this:
http://www.vt-2004.org/Background/Infol2/EIS-D7.html
I thought this would occur not below 900-1100 degrees celsius as in http://www.brocross.com/iwps/pages/lime.htm :
So my questions are:
What would be the lower temperature limit for " at high temperature chemical reactions begin to drive carbon dioxide from the rocks into the atmosphere"
What would be the effect of high atmospheric CO2 pressure on that temperature?
Any experts on lime burning?

Another runaway effect occurs when high temperature chemical reactions begin to drive carbon dioxide from the rocks into the atmosphere
I thought this would occur not below 900-1100 degrees celsius as in http://www.brocross.com/iwps/pages/lime.htm :
Limestone is a sedimentary rock composed principally of calcium carbonate and it can be calcined by heating it in a kiln. The heating process chemically converts the stone to burnt lime (quicklime, calcium oxide, CaO). To do this the stone must be heated to a temperature of between 900° and 1100°C. This causes the limestone to dissociate yielding burnt lime and carbon dioxide gas.
So my questions are:
What would be the lower temperature limit for " at high temperature chemical reactions begin to drive carbon dioxide from the rocks into the atmosphere"
