"It may very well be true that increased temps (caused by solar cycles for example) also drive CO2 as a result of biological activity or chemical cycles."

It does. There are several large carbon sinks that respond to changes in temperature. For example, arctic tundra ties up a lot of carbon. When the permafrost melts, it makes that carbon available to atmospheric oxygen. Likewise, warmer climates tend to change weather patterns and bogs become in danger of drying out. And then there is all the CO2 in ocean bottom water and if its temperature is raised that decreases the possible CO2 load it can carry. And finally, there are non-CO2 greenhouse gases like methane. Look up chlathrates if you want to know about a very real danger of increasing temperatures.
