At best they’re educated guesses. And, as the actual climate continues to demonstrate when compared to the outcomes the models predict (and that’s all they do is come up with a prediction based on how the huge numbers of variables have been set up in the algorithm they use), they’re woefully wrong about climate change. This comes under the category of “a picture is worth a thousand words” or in this case, a graph:
Not even close.
Now, who is the “denier”?
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.
This will throw an inconvenient kink in the Al Gore “earth has a fever” pitch, won’t it?
Could the best climate models — the ones used to predict global warming — all be wrong?
Maybe so, says a new study published online today in the journal Nature Geoscience. The report found that only about half of the warming that occurred during a natural climate change 55 million years ago can be explained by excess carbon dioxide in the atmosphere. What caused the remainder of the warming is a mystery.
“In a nutshell, theoretical models cannot explain what we observe in the geological record,” says oceanographer Gerald Dickens, study co-author and professor of Earth Science at Rice University in Houston. “There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models.”
As someone said recently, science is skeptism, and this is science. This is science taking another look and admitting “something’s just not right” with the current warming theories. And the problem begins with thier climate models.
The explanation is found in the earth’s history:
During the warming period, known as the “Palaeocene-Eocene thermal maximum” (PETM), for unknown reasons, the amount of carbon in Earth’s atmosphere rose rapidly. This makes the PETM one of the best ancient climate analogues for present-day Earth.
As the levels of carbon increased, global surface temperatures also rose dramatically during the PETM. Average temperatures worldwide rose by around 13 degrees in the relatively short geological span of about 10,000 years.
The conclusion, Dickens said, is that something other than carbon dioxide caused much of this ancient warming. “Some feedback loop or other processes that aren’t accounted for in these models — the same ones used by the Intergovernmental Panel on Climate Change for current best estimates of 21st century warming — caused a substantial portion of the warming that occurred during the PETM.”
One can only assume, if you want to go along with the oracle’s claims, that Fred Flintstone and his buddy Barney were driving their stonemobiles way to much. Except Fred and Barney weren’t even around then
The point made by Dickens is a solid one. If your model can’t “model” the past given all you know about it, how in the world can anyone have any scientific confidence in its modeling of the future? Here we have a period of the earth’s history (55.8 million years ago) in which man hadn’t even shown up on the scene yet, but where temperatures rose fairly drastically, globally, in a relatively short time (20,000 years). Why?
We’ve been led to believe that increases CO2 are the root cause and man is the reason for the rise in C02. But PETM seems to dispel that theory doesn’t it?
Nice to see science beginning to exert itself again as it reexamines what has become a mostly faith-based exercise in fear-mongering. Now if the politicians would only catch up.
A Japanese scientific report breaks with the “consensus”:
Scientists in the Land of the Rising Sun have concluded that it is the sun itself that is the major cause of Global Warming, not man.
It has been the sun for millions, if not billions of years previous to this warming trend. I have no idea, other than Al Gore, why we should believe this one is different.
Japanese scientists have made a dramatic break with the UN and Western-backed hypothesis of climate change in a new report from its Energy Commission.
Three of the five researchers disagree with the UN’s IPCC view that recent warming is primarily the consequence of man-made industrial emissions of greenhouse gases. Remarkably, the subtle and nuanced language typical in such reports has been set aside.
One of the five contributors compares computer climate modelling to ancient astrology. Others castigate the paucity of the US ground temperature data set used to support the hypothesis, and declare that the unambiguous warming trend from the mid-part of the 20th Century has ceased.
The report by Japan Society of Energy and Resources (JSER) is astonishing rebuke to international pressure, and a vote of confidence in Japan’s native marine and astronomical research. Publicly-funded science in the West uniformly backs the hypothesis that industrial influence is primarily responsible for climate change, although fissures have appeared recently. Only one of the five top Japanese scientists commissioned here concurs with the man-made global warming hypothesis.
Note the bold – that is precisely why this one is different. In previous warming trends, government funded scientists weren’t trying to prove it was man who was warming the earth. I also loved the bit about the models and ancient astrology.
