The reason its important to understand the ice age cycle is because we may be beating the global warming drum against a foregone trend.
Let me explain. The ice age is over due and may not be coming for reasons not related to CO2. If sudden ice melt, triggered by CO2, raised the earth crust, triggering the volcanic particulate and aerosol coverage to repeat the ice age cycle, then we had better know the underlying temperature trend, before global warming started. We need to know if earth is still gaining heat, over all, a very important question. Remember, underlying the ice age cycles is a temperature change of eight
deg Celsius, so whatever is not happening is not happening with a
global energy four times what we humans have caused. Where is the
missing energy?
If the volcanic trigger stopped, for whatever reason, then we gotta make a decision. Do we try for the holocene temperature using only co2 balancing? Too risky? How about simulate the volcano particulate and aerosol, for solar reflection in the upper atmosphere? If we are fubar, absent some serious geoengineering, then the best bet is to find out right away.
Which brings up the Gore satellite, a good idea. It would have given us accurate information about net energy losses and gains. If the earth needs ice time, then we are the human engineers, by survival. We have to move mountains and get the volcanoes going or we gotta spray the upper atmosphere. On the other hand, if the net energy gains are linear around the point that CO2 can control it, we have solutions coming along in the lab, direct synthesis of carbon materials.
So, get the Gore satellite up there, and accelerate the research into direct conversion of CO2 into stable carbon forms and look all over the world for layers of volcanic dust that can be dated. Would volcanic dust, a few years wide, appear in one of the ice cores?
