Whoever said all things are 'equal'???
I view Co2 as an insulator...it regulates temperature, so if we increase the concentration....but the 'heat source' cools, then the global temperature will cool, but at a slower rate, and if the 'heat source' warms, then the global temperature will rise, again at a slower rate..
Yup. You sound exactly like a creationist. Pseudo scientific drivel.
That's all good and well but when the 'heat source' 'warms' or 'cools' throughout geological history the changes have been relatively slight, certainly not strong enough to cause the dramatic changes that they DO cause without the climate having the sensitivity to CO2 that mainstream climate science suggests. So your little thought eperiment really falls flat in the face of evidence.
Quote:The initial changes in temperature during this period are explained by changes in the Earth’s orbit around the sun, which affects the amount of seasonal sunlight reaching the Earth’s surface. In the case of warming, the lag between temperature and CO2 is explained as follows: as ocean temperatures rise, oceans release CO2 into the atmosphere. In turn, this release amplifies the warming trend, leading to yet more CO2 being released. In other words, increasing CO2 levels become both the cause and effect of further warming. This positive feedback is necessary to trigger the shifts between glacials and interglacials as the effect of orbital changes is too weak to cause such variation. Additional positive feedbacks which play an important role in this process include other greenhouse gases, and changes in ice sheet cover and vegetation patterns.
