Cosmic rays are another key driver of global warming. The suggestion here is that cosmic rays from far deep space play a much larger role in global warming than any man made effects. Of course the level of cosmic rays hitting the earth is supposedly related to the level of the sun's activity and is thus related to the previous point.
Gray reports on findings which suggests the role of cosmic rays in global warming and outlines the process by which this could happen. Scientists link the intensity of the cosmic rays to the level of the sun's magnetic field. When the sun's magnetic field is less active, there is an increase in amount of cosmic rays the penetrate the earth's atmosphere. There is a resultant decrease in earth's cloud cover and, as a result, global cooling would ensue.
I like the way you started with the sun and then went on to discuss cosmic rays - the progression seemed very coherent.
