Cosmic Rays Do Not Explain Global Warming, Study Finds

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.

yeah, I know. But that’s the dirty job of freeping: to put out what’s out there so that other freepers can give their take on the news.

Ya know,,,, it would save a lot of energy if they’d turn that thing off in the daytime!

Cosmic rays are too minuscule to create a warming trend but minuscule amounts of additional CO2 from humans is creating a warming trend without a doubt?

it would save a lot of energy if they’d turn that thing off in the daytime!

AND if they would turn it on at night! Then I wouldn't have to run the furnace as much.

Well we know it’s not carbon dioxide.

Cosmic rays?! WHAT A BUNCH OF IDIOTS!!! LOL!!!

[ChessExpert]

You are right. It is not cosmic rays by themselves; as the headline states.

The hypothesis is that the interaction of cosmic rays and solar wind affect cloud formation and earthly temperatures. As you stated, the variability (warming or cooling) is due to our sun.

The article talks of global warming during the last decades. But I don’t think there has been any global warming in the last ten years.

If we can’t get the Y (dependent variable) value right, why debate about the X (independent) variable?

IE: a think tank set up to create data to support global-warming lunacy. Otherwise it would be a Center for Atmosphetic Science, or something like that.

Actually, the term “cosmic rays” includes gamma emissions from the sun. But also see post #6.

It is the combination of increased Cosmic Rays and Decreased Solar Energy that cause Global Cooling. Just look at what is happening in the Northern US this winter for an example of the process. Record snow levels, record cold. Science that is backed by real time observation. Gee. What a concept. So conversely, the combination of Decreased Cosmic Rays and Increased Solar Energy causes Global Warming and Drought. That theory just gained weight in Eastern Australia by examining drought rates over the last 100 years.

Coming soon! A study on the effects of moonlight and global warming. (Hint:save the research money. Moonlight has no impact on Gorebull warming.)

Forgot to add, one must also factor in Volcanic activity to get through the noise in the data. Volcanic activity on land tends to cool the Earths surface. Volcanic activity under the ocean tends to warm the Earths surface. By Earths surface what is really meant is the Earths Oceans, where most of the heat content resides.

Beam me to Planet Gore !

[Robert A Cook PE]

“Kristjansson and his collegaues have used observations from so-called Forbush decrease events: Sudden outbreaks of intense solar activity that lead to a strong reduction of cosmic rays, lasting for a couple of days. The researchers have identified 22 such events between 2000 and 2005.”

Hmmmn.

So, the research DID SHOW that higher levels of solar activity (22 times in those few years) measurably changed the cosmic ray flux.

Now, they claim found no change in cloud cover (in the southern hemisphere ocean regions at least).

But, these guys DID find changes in cosmic ray flux from a change in solar energy - NOT a change in solar “illumination - which what Hansen and his ilk keep repeating.

maybe somebody should tell the Center for Climate and Environmental Research that the entire solar system is warming, not just earth.

“Neptune’s moon, Triton, studied in 1989 after the unmanned Voyageur probe flew past, seems to have heated up significantly since then.....Even Pluto has warmed slightly in recent years, if you can call -230C instead of -233C “warmer.”

I doubt Cosmic Ray is in a condition to explain much of anything.
