Makes sense. One factor that goes right along with this scenario, but is not mentioned in the video, is that melting ice caps releases fresh water into the oceans, which affects their salinity and therefore their density. This causes warmer surface waters flowing from the equator northward to sink lower in the water column which in turn affects ocean temperatures. Surface heat from the sun then warms water lower in the ocean, and the heat released there is of course being taken away from the surface, making overall temperatures cooler.
So, for example, the temperatures in the British Isles, which are artificially warmed by the Gulf Stream carrying equatorial heat northward and past Ireland and England and Scotland, take a turn for the cooler as their normal warming effects are being released closer to the bottom of the Atlantic.
This has the effect of cooling the north in general, which promotes the re-formation of the ice caps, and in extreme examples adds it's effect in the production of ice ages.
