solar cycles
Another one in the eye for the solarists. K. Rypdal, JGR VOL. 117, D06115, 14 PP., 2012 doi:10.1029/2011JD017283:
I show that the peak-to-peak amplitude of the global mean surface temperature response to the 11-year cyclic total irradiance forcing is an order of magnitude less than the amplitude of a cyclic component roughly in phase with the solar forcing which has been observed in the temperature record in the period 1959-2004. If this cyclic temperature component were a response to the solar forcing, it would imply the existence of strong amplifying feedbacks which operate exclusively for…
