The findings by CERN which have finally been published in Nature magazine, are fairly explicit about the validity of current AGW models. They will need to be “substantially revised”.
Because the findings substantiate the fact that the sun plays the major role in changes in our climate and not the human factors claimed by warmists. It’s all about the sun, clouds, cosmic rays and nucleation.
CERN conducted a CLOUD ("Cosmics Leaving OUtdoor Droplets") experiment to test a theory at odds with current warmist theories about cloud origins. As it turns out, the findings provide:
… support for a "heliocentric" rather than "anthropogenic" approach to climate change: the sun plays a large role in modulating the quantity of cosmic rays reaching the upper atmosphere of the Earth.
Who knew that big yellow hot thing that hangs in the sky each day would play a major role in our climate?
Prior to publication of the Nature article, it had been assumed the findings were negative to warmist theories when the head of CERN (director-general Rolf-Dieter Heuer) warned his scientists to just provide the facts and not interpret them.
Here’s how CERN presented the data via lead physicist Jasper Kirkby:
"Ion-induced nucleation will manifest itself as a steady production of new particles that is difficult to isolate in atmospheric observations because of other sources of variability but is nevertheless taking place and could be quite large when averaged globally over the troposphere."
Kirkby is quoted in the accompanying CERN press release:
"We’ve found that cosmic rays significantly enhance the formation of aerosol particles in the mid troposphere and above. These aerosols can eventually grow into the seeds for clouds. However, we’ve found that the vapours previously thought to account for all aerosol formation in the lower atmosphere can only account for a small fraction of the observations – even with the enhancement of cosmic rays."
"[I]t is clear that the treatment of aerosol formation in climate models will need to be substantially revised, since all models assume that nucleation is caused by these vapours [sulphuric acid and ammonia] and water alone.
Here is another unknown finally known. Yet the scientists on the warmist side tried to claim they had all the information they needed to build their models and make their wild claims. However, as more and more real science comes it, it becomes clearer and clearer that their science falls at best in the “junk science” category and their claims are unsubstantiated assertions. As we’re finding out, they’re certainly not backed by science.
So, what should be taken from this? A) the climate models are junk. Most observers have known this for quite some time. They are incomplete, their forcing data are all out of whack, and they not only can’t forecast the future, they can’t reproduce the past. B) We’re really just now beginning to understand the climate and its dynamics. And, unsurprisingly for most, despite the warmists attempts to ignore it, the sun plays a major role in determining temperature on earth.
Seems like common sense to me. So why has it taken so long to finally surface?
As with all such things, follow the money.
One of the things I and others have been saying for years is the biggest influence on our climate (and temperature) hangs in the sky each day and we call “the Sun”. Anthony Watts has a post up today talking about what is going on with the Sun and what that may mean for global temperatures. The process, as I have come to understand it is activity on the Sun (sun spots) generate solar winds (sun’s magnetic field). Solar winds have a tendency to “blow” away cosmic rays and keep them from reaching earth. When cosmic rays reach earth they react with water vapor in our atmosphere and create clouds. Clouds then block sunlight. Heavy cloud cover means cooler temperatures. Light cloud cover means higher temperatures. As I further understand it, none of that is included in climate models.
Well, if Svensmark is right, and Galactic Cosmic Rays modulated by the sun’s magnetic field make a change in cloud cover on Earth, increasing it during low solar magnetic activity, we are in for some colder times.
There’s a presentation by Jasper Kirkby, CLOUD Spokesperson, CERN, which shows what we currently know about the correlations between Galactic Cosmic Rays (GCR’s) and variations in the climate.
The CLOUD experiment uses a cloud chamber to study the theorized link between GCR’s and cloud formation in Earth’s atmosphere. Kirkby talks about the results from the first CLOUD experiment and the new CLOUD experiment and what it will deliver on the intrinsic connection between GCR’s and cloud formation. This is from the Cern, one of Europe’s most highly respected centers for scientific research.
The sun is in a funk – has been for years. Some of the lowest activity every recorded. And what has been happening here? Recorded temperatures have been cooling. Perhaps the funniest (in a sad sort of thing) thing I’ve read are the so-called climate scientists who were lamenting their inability to explain why their models weren’t reflecting this cooling trend and wishing they could explain it.
Look at the charts on Watts’ site, read about the lack of activity on the sun, understand the relationship between activity, solar winds, cosmic rays and clouds and you’ll understand that this is high school science we’re talking about.
Now go read this, especially the commenter’s remarks highlighted in the article, and much of what is going on becomes considerably clearer.
Which leaves me asking – again – how can such “science” that disregards the sun’s effect and raises an 800 year lagging effect (CO2) into a “cause” be taken seriously by intelligent and seemingly rational adults? Forget “consensus” and “conspiracy”. How did the Sun get ignored and CO2 changed from effect to “cause” in this hypothesis which can’t be reproduced?
