A study "linking" #cosmic rays & #aerosols/cloud formation via #solar activity was posted on WUWT
This is a theory which does not work
. My Comment on the Article was posted on WUWT 18May 4:50pm as below:
Cosmic Rays and solar activity are inverse proxies of each other so seeing one does not mean the other causes anything. An observed relation between solar activity and any earth atmospheric variable does NOT need Cosmic rays as the agency. The agent can be (AND IS!) solar particles themselves which have 300 times the energy flux on average of cosmic rays. Cosmic Rays are a side show.
The clincher is that if Cosmic Rays are the agents linking solar activity to the earth's atmosphere then since they follow the suns' 11 year cycle then world temperatures should mainly follow the 11 yr cycle BUT THEY DO NOT. They follow the 22 year magnetic cycle which guides solar particles in magnetically sensitive ways. Please see the Climate Realist thread on this World cooling has set-in warns astrophysicist - BBC & 'Global Warming apologists' challenged to end 'cover-up'
And let us be clear when, using predicable aspects of solar activity, we at WeatherAction.com forecast extreme weather events with high skill we OBSERVE the chain of being:
solar activity (eg X flares, fast solar wind proton bursts etc) =>ionospheric/magnetic effects=> jet stream shifts / tornadoes / weather.
THERE ARE NO OBSERVED MODULATIONS OF COSMIC RAYS ON THESE SHORT TIME SCALES SO THEY CANNOT BE THE AGENTS OF WEATHER CHANGE OR CLIMATE CHANGE. (climate being the sum of weather over a long time)
