Episodes of relative global warming

Solar activity is regulated by the solar dynamo. The dynamo is a non-linear interplay between the equatorial and polar magnetic field components. So far, in Sun-climate studies, only the equatorial component has been considered as a possible driver of tropospheric temperature variations. We show tha...

description Solar activity is regulated by the solar dynamo. The dynamo is a non-linear interplay between the equatorial and polar magnetic field components. So far, in Sun-climate studies, only the equatorial component has been considered as a possible driver of tropospheric temperature variations. We show that, next to this, there is a significant contribution of the polar component. Based on direct observations of proxy data for the two main solar magnetic fields components since 1844, we derive an empirical relation between tropospheric temperature variation and those of the solar equatorial and polar activities. When applying that relation to the period 1610-1995, we find some quasi-regular episodes of residual temperature increases and decreases, with semi-amplitudes up to ∼0.3 °C. The present period of global warming is one of them. © 2008 Elsevier Ltd. All rights reserved.
