Henrik Svensmark: The Cosmic-Ray/Cloud Seeding Hypothesis Is Converging With Reality
Friday, 02 September 2011 14:54 Dr. David Whitehouse
Dr Henrik Svensmark of the Danish National Space Centre in Copenhagen has pioneered the study of the effects of cosmic rays on cloud formation. The GWPF put a series of questions to him concerning the recent results from CERN’s CLOUD experiment. (GWPF)
Lawrence Solomon: Our cosmic climate
CERN experiment overturns global-warming orthodoxy
The 20-year-long global warming debate is in its final stages, the controversy having been settled over whether manmade causes such as carbon dioxide or natural causes such as the Sun dominate climate change on Earth. (Financial Post)
Alarmists Got it Wrong, Humans Not Responsible for Climate Change: CERN
Global warming and climate change are phenomena that broke the bonds of scientific circles to emerge as a matter of debate between “believers” and “skeptics.” Countless studies validating and denying global warming have seen the light of the day, providing fodder for more, often somewhat bitter debates. Within the past month, Nobel Prize winner and leading climate change “alarmist” Al Gore has called those who deny global warming akin to “racists,” and “pseudo-scientists,” and accused media of manipulating evidence about global warming.
Research findings published by none other than CERN, the European Organization for Nuclear Research, in the journal Nature which holds cosmic rays and the Sun, not human activities, responsible for global warming, isn’t exactly what Gore would welcome right now. (IBT)
Lorne Gunter: The sun shines some light on global warming orthodoxy
Last week, 63 scientists from CERN, the unimpeachable European Organization for Nuclear Research, published a paper in the journal Nature that would seem to prove that the sun and not humans is the main “driver” of climate on Earth.
In short, cloud cover is the most important determinant of global warming or cooling. Tiny changes in the percentage of Earth shielded by clouds (or not) can cause a variation in global temperatures of several degrees, down or up. Cosmic rays are the main cause of cloud formation – the more rays from outer space reaching our planet’s atmosphere, the more clouds form and the cooler the surface becomes.
In turn, the amount of cosmic rays penetrating our atmosphere is determined by the activity of the sun’s magnetic field. When our sun is particularly active, it blocks cosmic rays. This reduces cloud formation, permits more solar rays to reach Earth and increases global temperatures.
By comparison, the CERN team found human CO2 emissions have little or no impact, or at the very least their impact has been greatly overestimated in the computer models global-warming alarmists rely on to show dangerous future climate.
So why hasn’t this been headline news around the world? After all, global warming and what to do about has been perhaps the biggest public policy issue of the past decade, with the possible exception of the worldwide financial crisis. (Both revolve around whether more government intervention and spending is the best way to solve large-scale problems.) (National Post)
CLOUD Rains on Climate Theory
James Delingpole
“It’s the sun, stupid.” This was the excited conclusion many readers drew from a recent much-read blogpost of mine about the latest results from the CERN laboratory in Geneva, Switzerland. The story concerned a major experiment called CLOUD (Cosmics Leaving Outdoor Droplets) and seemed to confirm everything that the world’s growing band of “skeptics” would dearly love to hear: that the sun, not man-made CO2 is by far the most important factor in “Climate Change.”
Actually, though, the story’s more complicated than that. And, in many ways, more interesting. Yes, the experiment did lend encouraging credence to the theory by the Danish physicist Henrik Svensmark that solar radiation may play a significant role in seeding the clouds which warm (and cool) the planet. But what it didn’t do was prove anything except that this is a promising area and that more research needs to be done.
What it did do very much to confirm, though, was the extreme establishment bias which has corrupted and debased the whole debate about Anthropogenic Global Warming. The real story lay, not in the experiment’s tentative findings, but in the insistence by CERN’s own Director General Rolf-Dieter Heuer, that it wasn’t a story. (Energy Tribune)
