A new study supports earlier findings by stating that changes in cosmic rays most likely do not contribute to climate change. It is sometimes claimed that changes in radiation from space, so-called galactic cosmic rays, can be one of the causes of global warming. A new study, investigating the effect of cosmic rays on clouds, concludes that the likelihood of this is very small.
A group of researchers from the University of Oslo, Norwegian Institute for Air Research (NILU), CICERO Center for Climate and Environmental Research, and the University of Iceland, are behind the study.
Unlikely that cosmic rays affect global warming
There are scientific uncertanties about cosmic rays and cloud formation. Some researchers have claimed that a reduction of cosmic rays during the last decades has contributed to the global temperature rise. The hypothesis is that fewer cosmic rays causes fewer cloud droplets and reduced droplet size, and that this again causes global warming, since reduced cloud droplets would reflect less energy from the sun back to space. However, the researchers who stick to this hypothesis find little support amongst colleagues.

Silly us thinking that the giant flaming orb in the sky might affect our temperatures!
Cosmic rays are much different than solar thermal radiation.
I love it when we speak truth to power!
Actually they do.
The theory is that solar wind drives back the cosmic rays and prevents some of them from reaching earth.
Since cosmic rays cause clouds, more solar wind means fewer cosmic rays means fewer clouds means more absorption of radiant heat from the sun means higher temperatures.

How convienient. What made them make such a silly claim, Satan?
One can easily detect the bias of an article by noting whether the phenomenon is being considered to affect “global warming” or “climate change”. The former assumes global warming and shows that the writer is primarily concerned with shoring up their failing theory.
How hilarious.
The sun, which is the ultimate source of warmth on the earth and daily heats and cools us, couldn’t possibly be the cause of temperature variations.
No, the real culprit has to be an increase of carbon in the atmosphere from 350 per MILLION to 370 or so!
This reminds me of THE LAST CENTURION, a current novel absolutely every freeper should read. The narrator, an unapologetic conservative, is apoplectic with the idiots who continue to trumpet global warming nonsense even as the planet slips into a “mini ice age.”

This is their “core sample,”
[By focusing on pristine Southern Hemisphere ocean regions, the researchers examined areas where a cosmic ray signal should be easier to detect than elsewhere.]
Ignaz Semmelweis stuck to his hypothesis that "childbed fever" could be lessened/prevented if doctors attending women who had recently given birth washed their hands well between patients, despite finding little support amongst colleagues.
Copernicus stuck to his hypothesis that the Earth was not the center of the universe, despite finding little support amongst colleagues.
As Michael Crichton put it,
Though occasionally there are high energy bursts such as stars in supernova even in other galaxies, and even more energetic sources such as pulsars and quasars near the event horizon at ~14 billion years distant.
Yet, being periodic in nature, it does seem difficult to specifically tie these to any long term atmospheric events over about 4 billion years here.
...Such a strange and beautiful universe of God....
it’s great to know that there’s conservative sci fi out there.
There are decades of research correlating ice core samples to solar activity. Researchers can see the cores correspond. There is research correlating mud core samples that correlate climate change to solar activity.
