New paper finds another amplification mechanism by which the Sun controls climate
A paper published today in Advances in Space Research finds small changes in solar wind speed may affect both the North Atlantic Oscillation [NAO] and the Arctic Oscillation [AO] on both short-term [day-to-day] and long-term [inter-annual] timescales. Both the NAO and AO in turn have major effects upon global climate. The authors propose these effects are related to "A connection via the global atmospheric electric circuit and cloud microphysical changes" [similar but not the same as the cloud seeding hypothesis of Svensmark et al]. The paper may demonstrate yet another amplification mechanism by which tiny changes in solar activity can be amplified to produce large effects upon climate.
