What they fail to explain is that "positive feedback" (aka "feed forward" loops) have the interesting characteristic that they culminate in some climatic event. An example is orgasm. What, I wonder, does he propose as the culminating event to this feed forward scenario?
Look at CO2 like a Stockmarket Analist would. It is a "trailing indicator". It confirms what HAS HAPPENED.
It has never been a valid PREDICTOR.
Much too gross an oversimplification. When a glacial-interglacial or interglacial-glacial transition is initiated, many factors are in place such that, when a trend is initiated, they have self-reinforcing feedbacks (positive or negative, depending on your viewpoint).
Leaving CO2 totally out of the discussion for a moment, the other main factor is the extent of continental glaciation. When the continental ice sheets start to retreat, Earth's albedo (reflectivity) decreases, allowing more solar radiation to "enter the system" and not get immediately reflected right back into space. And the exposure of land surface is one of the main ways it enters the system, because the land absorbs solar radiation and re-radiates it as longwave infrared. And we know what happens to that, right? Plus, warmer land surfaces adjacent to glaciers are likely to be wet, releasing water vapor into the atmosphere, increasing relative humidity.
So that's an example of a non-mysterious process that would augment an initiated warming trend. And I'm working in my profile to explain the CO2 feedback in detail.
