Cosmic Rays are Decreasing

July 26, 2022: Cosmic rays in the atmosphere are rapidly subsiding. In the past year alone, radiation levels in the air high above California have plummeted more than 15%, according to regular launches of cosmic ray balloons by Spaceweather.com and Earth to Sky Calculus. The latest measurement on July 23, 2022, registered a 6 year low:

This development, while sudden, is not unexpected. Cosmic rays from deep space are repelled by solar activity; when one goes up, the other goes down. Since 2021, Solar Cycle 25 has roared to life faster than forecasters expected. The onset of the new solar cycle has naturally led to a decrease in cosmic radiation reaching Earth.

To many readers this may sound counterintuitive. After all, don’t solar flares produce radiation? Yes, but most high-energy radiation doesn’t come from the sun; it comes from deep space.Every day galactic cosmic rays from distant supernova explosions…

    If it’s going to cool we need more cosmic rays/less solar winds. Not ;ess/more.

    Are solar winds up though?

    Is this just Calfornia – don’t see how it can be, IF it’s correct? But youknow what they’re like.MIght be the UFOs or Bigfoot, whatever the Quiche Eatering Scientologists at JPL believe in at the moment. etc.

    Cosmic ray data here…

    We don’t see much evidence for weather/climate varying with single solar cycle intervals, suggesting not much of a role for cosmic rays, on that timescale at least.

    I am puzzled that the relationships and cycles we know about in the subject are not also mentioned. as any report of merit should mention what we know happens. A few years of Californian records are hardly definitive of any natural change and do not seem to distinguish between cosmic rays and solar winds, which are quite different, of course. e.g. Not cosmic.

    There is a well established 11 year radiation activity (also wind?) cycle which is VERY well reported. Also there are several longer period cycles reported by Steinhilber and others,

    and well reported by Ludecke and WEiss as correlated with frequencies in the global temperature time series..

    These included 1Ka, 500a , 200a and 60a from memory. So this is probably some noise, or more likely the edge of a change. Time will tell.

    From recollection the natural cycle of the combined effects of solar wind cycles should be decreasing now over the longer time and dominant 1Ka period to create long term cooling within the 1Ka climate cycles we observe in the natural record – everywhere else except in IPCC models. But Archeology is now appearing from under glaciers, dated by…. C-14 created by Cosmic rays. Bit ofa give away. Games up IPCC.

    They hate real science you measure that denies what they make up in political science models. It will be interesting to follow solar wind change on a more global basis. Solar wind should be the same everywhere at a given latitude what with all the spinning around on its invisible rotiserie in front of the Sun.

    PS, as a radiation physicist I’d like to see a balloon cosmic Ray detector. How do you detect a seriously hard to stop 140MeV cosmic proton with something hanging underneath a balloon and separate that from a less energetic more stoppable Solar Proton? (sure there is a way, but what?).

    QUESTION: If this report is wrong and in fact solar winds are being measured and called cosmic rays, so we in fact have decreasing solar wind and increasing cosmic rays, that would be different, and in line with the past. Just sayin…..
