The fact remains, there is climate change… It’s just not man-made
There is non-manmade CO2 climate change, but that ice age cycle is normally 110,000 years lone, and we have condensed it to only 200 years or so.
Don't get confused by things like the Medieval warming around 1300 and the Little Ice Age around 1600.
Those variations are caused by known events like solar cycles, earth orbit precession, volcanic activity etc., which we know are not relevant to current global warming.
The big difficulty is understanding how such a small concentration of CO2 can make any difference at all requires understanding the upper troposphere. At that altitude, water vapor pretty much all condenses out because it is about 100 degrees below zero. And at that altitude, the only way energy that came from the sun can leave the earth, is as photonic infrared radiation. But CO2 is relatively opaque to infrared, and will not let it leave to any large degree. And energy can not leave by any other means, like convection or conduction.
