On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on feedbacks, since I don't see a contradiction between an internal radiative forcing and positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray hypothesis.

If one postulates that the global average surface temperature tracks the CO2 concentration in the atmosphere, possibly with some delay, then when the CO2 concentration continues to rise monotonically but the global average surface temperature shows fluctuations as a function of time with changes in slope (periods wherein it decreases), then you must throw the postulate away.
