Cosmic Rays Increasing According to

Meteorologist Paul Dorian writes about a Study, which was reported on here in January 2016.

Current cosmic ray activity

We happen to be in a weak solar cycle (24) which is actually on pace to be the weakest cycle in more than one hundred years. Therefore, it would not be surprising to have relatively high cosmic ray penetration into the Earth’s atmosphere; especially, since we are now heading towards the next solar minimum phase when solar activity is generally even quieter. During solar maximum, CMEs are abundant and cosmic rays are held at bay.

In fact, for the past year, neutron monitors around the Arctic Circle have sensed an increasing intensity of cosmic rays. Polar latitudes are a good place to make such measurements, because Earth’s magnetic field funnels and concentrates cosmic radiation there. As it turns out, Earth’s poles aren’t the only place cosmic rays are intensifying. “” has led an effort in the launching of helium balloons to the stratosphere to measure radiation, and they find the same trend increasing intensity of cosmic rays over California. Their latest data show an increase of almost 13% since 2015. [For more on this study click here]:

In the plot, neutron monitor measurements from the University of Oulu Cosmic Ray Station are traced in red; gamma-ray/X-ray measurements over California are denoted in gray. The agreement between the two curves is remarkable. It means that the intensification of cosmic rays is making itself felt not only over the poles, but also over lower latitudes where Earth’s magnetic field provides a greater degree of protection against deep space radiation. There’s a new section on where you can monitor cosmic rays in the atmosphere.

As reported elsewhere on this blog, here,  more cosmic ray has been shown to produce more clouds, and more clouds reduce the plant’s temperature.  We can expect some cooler climate as Solar Cycle 24 sunspots and CMEs decline.

  1. Cosmic rays and solar activity are also a good fit with increasing and decreasing co2 levels per year. The high and low points in co2 levels follow solar activity. However, cosmic ray activity influences that as well as in the record from 1962/1963. …. we will see… it will be an interesting next couple of years if the solar activity diminishes and is longer than the last one.
    I have ideas that aren’t quite tangible yet without further evidence. It is difficult in one dimensional thinking (co2 as the control knob) that only one factor is involved in changes in climate, long term. When in fact, two or more vectors can buck or boost. I get into that all the time with the decline of the magnetic field strength of the earth. Yea, well, it might not be microwave energy, ( the amount of microwave energy so small it wouldn’t melt a snowflake, so I’ve been told, what’s in the Van Allen radiation Belt? That’s why the ISS flies in a low earth orbit) but it might be something else . And that something else combined with a solar activity with cosmic ray amounts does.
    I am puzzled by a statement here. In the electromagnetic spectrum, magnetism, magnetic fluxes from electromagnetic pulses, like lighting, has no effect on light which is in the middle of the energy band. Magnetism does have an effect on lower frequency energies up to the IR. How is it that cosmic rays are effected by a magnetic field? I understand the concept behind making an oscilloscope. Perhaps the magnetic field traps a cloud of particles that the cosmic rays interact with that increase or decrease the amount we see. Now a gravitational field would be another matter.
    I think the situation is a complex one with many interdependent vectors. I just haven’t worked them all out yet. Official government sites and others that are continually readjusting the data to fit the models doesn’t help.

    * on any space ship ( I don’t mean these little tin cans we float around in) I would design, would have a magnetic bubble around it. Further, on any other planet that doesn’t have a magnetic field, I’d generate one. Instead of all this money wasted on climate, I’d be building the biggest baddest starship. We need to have diversity in where we live. Earth just isn’t that safe of a place.
