The sun also generates massive magnetic fields and changes in solar activity changes these magnetic fields. (judithcurry.com)

There are very short - term trends (e.g. the ENSO) having a short up - or - down effect on the global surface temperature, but which (when you think it through) are incapable of altering the long - term climate trends produced by real drivers of climate change (e.g. long - term solar activity changes / Milankovitch - cycle insolation / Northern Hemisphere ice albedo changes / continental drift positional effects / and of course Greenhouse gas alterations).
