A paper published today in the Journal of Geophysical Research describes an additional mechanism by which small changes in solar activity are amplified to cause climate change.
According to the authors, the “mechanism describes how solar UV changes can lead to a significant enhancement of the small initial signal and corresponding changes in stratospheric dynamics”, which in combination with a natural atmospheric circulation, the Quasi-Biennial Oscillation, causes a “significant ocean response,” alterations of the Southern Annular Mode, wind anomalies, and deviations in ocean currents. The IPCC dismisses the Sun as a cause of recent climate change by assuming solar activity is a constant [the "solar constant" or TSI], and by ignoring amplifying factors on solar activity such as clouds, sunshine hours, ozone, large changes in solar UV within and between solar cycles, and the mechanism described by this new paper.
