Very insightful. We are in a, relatively speaking, very brief warm period between ice ages. Add to the fact that there is only a microscopic amount of man-made global warming and we would be tinkering with processes that are stable and, in fact, self-regulating.
I seem to remember a fiction book that came out some time ago. The premise, if I recall correctly, was that the Sierra Club manage to pass legislation to 'help the environment' that brought about an early ice age. Anyone remember this? It must have been about 20 years ago or thereabouts.
Actually, the Holocene is a long and remarkably stable interglacial already. Milankovitch cycle solar forcing impacts are expected to be low so it is projected to continue for several thousand years more.
