You wrote, "I don't know however how increased global climate temperatures could be responsible for increased carbon dioxide emissions. Perhaps the increased temperature releases carbon dioxide dissolved in the oceans but I don't know what consequence that would have otherwise than if the greenhouse effect."
It evidently does release CO2 from the ocean, but surprisingly the increase in atmospheric CO2 appears to have had little effect on global warming. If we look at the record of arctic-wide surface air temperatures from 1870 to 2000, there is virtually no correlation between air temperature and atmospheric CO2. In fact, between about 1920 and 1970, there is a large divergence. On the other hand, what we do find during that period is an almost perfect correlation between arctic air temperature and solar radiation.
