Someone else in this thread thought differently saying : "It's gotten brighter over even just the last 20 million years. The ice caps helped reflect nearly .39 of it, but soot and melting are lowering that. It's called albedo and that loss will dwarf the CO2 Heat trapping." Similarly I found that in the geologically recent past, the ice–albedo positive feedback has played a major role in the advances and retreats of the Pleistocene (~2.6 Ma to ~10 ka ago) ice sheets and that the ice at the arctic is in fact not that negligible given the loss of it in relation to the much higher warming at the poles. To what extent do you believe clouds contribute?
