Cosmic Rays Increase Cloud Cover, Earth’s Surface Cools



A new scientific paper authored by seven scientists affiliated with the Russian Academy of Sciences was just published in the scientific journal Bulletin of the Russian Academy of Sciences: Physics.

The scientists dismiss both “greenhouse gases” and variations in the Sun’s irradiance as significant climate drivers, and instead embrace cloud cover variations — modulated by cosmic ray flux — as a dominant contributor to climate change.

A concise summary: As cosmic ray flux increases, more clouds are formed on a global scale. More global-scale cloud cover means more solar radiation is correspondingly blocked from reaching the Earth’s surface (oceans). With an increase in global cloud cover projected for the coming decades (using trend analysis), a global cooling is predicted.

Spaceweather has shown a 12% increase in cosmic rays from October 2015 to September 2016.


Why are cosmic rays intensifying? The main reason is the sun. Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth’s magnetic field, which helps protect us from deep-space radiation.

I think the Russian Scientists are providing some valuable insight. As the sun goes quiet, we should see an increase in cosmic rays and increasing cloud cover, thus cooling of the planet.  The sun is modulating our climate by shrinking or expanding the earth’s magnetosphere, which has an impact on the number of cosmic rays reaching our atmosphere.

Watch Spaceweather as they are expanding their cosmic ray collection network.

Where can we find the best real-time cloud coverage to monitor the cosmic ray connection to cloud cover?

We live in interesting times.

    Solar wind strength is a key factor.

    ‘The flux of incoming cosmic rays at the upper atmosphere is dependent on the solar wind, the Earth’s magnetic field, and the energy of the cosmic rays…However, the strength of the solar wind is not constant, and hence it has been observed that cosmic ray flux is correlated with solar activity.’

    A much more plausible theory than CO2 being a driver….and one that is growing in ” consensus. Heck, it might reach the magical 97%. At which point it will be deemed a fact.

    Russ, not sure if you would be surprised to hear this, the other night I was listening to a radio show where it involved a climatologist and a airline industry spokesmen or lobbyist apparently they are dead worried about the impact of turbulence will have once the Grand Solar Minimum intensifies

    No hat-tip to Svensmark (sp?) ?

    When will the cloud cover age change so that even the, “average Joe” will start to notice?
