This is also why global warming alarmists try to do their best to quench anything related to the the solar variability → cosmic ray flux → atmospheric ionization → low altitude cloud cover link which by now has ample evidence for support, both empirical and experimental. (sciencebits.com)
There has been a lot of interest in the relationship between ENSO and the AAO with better correlation in some seasons than others but little realization that the northern trades and the southern exhibit very different behaviors, that the Arctic contributes, that the flux in ozone comes from the Arctic more than the Antarctic, this affecting mid latitude high altitude cloud cover.

Another near - term feedback is the reduction ocean - spray DMS aerosols that will contribute.2 -.4 C additional warming and the recent model results of decreased low - altitude cloud cover under warming scenarios (additional.2 -.5) (skepticalscience.com)
