I have been following the results of the all the experments that infer cosmic rays have an implact on the earth climate ever since reading Chilling Stars by Danish scientist Henrik Svensmark. The book was about his research into the effects that cosmic rays have on cloud formation and resulting inpact on climate change. Chilling Stars co-author was Nigel Calder.
Here is the latest from Calder on the status of the CLOUD experiment that was to prove or disprove Svensmark's therory about the connection between cosmic rays and the earths climate.
Nigel Calder: CERN Chief Forbids “Interpretation” Of CLOUD Results
Although still very busy with other work, I keep looking out for results from the CLOUD experiment at CERN in Geneva, which is testing Henrik Svensmark’s hypothesis that cosmic rays help to make clouds. They are due for publication this summer. All I have just now is a startling remark by Rolf-Dieter Heuer, Director General of CERN, in an interview by Welt Online a few days ago.
Here is a tidied-up Google Translate version of the relevant exchange.
Welt Online: The results of the so-called CLOUD experiment, exploring the formation of clouds, are awaited with great excitement. Could these results still be important for understanding global climate change?
Heuer: This is indeed a matter of understanding better the formation of clouds. In nature there are many parameters at work – including temperature, humidity, impurities and also cosmic radiation. In the experiment, CLOUD investigates the influence of cosmic rays on cloud formation, using radiation [meaning particles] coming from the accelerator. And in an experimental chamber one can study, under controlled conditions, how the formation of droplets depends on the radiation and particulate matter. The results will be published shortly. I have asked the colleagues to present the results clearly, but not to interpret them. That would go immediately into the highly political arena of the climate change debate. One has to make clear that cosmic radiation is only one of many parameters.
Four quick inferences:
1) The results must be favourable for Svensmark or there would be no such anxiety about them.
2) CERN has joined a long line of lesser institutions obliged to remain politically correct about the man-made global warming hypothesis. It’s OK to enter “the highly political arena of the climate change debate” provided your results endorse man-made warming, but not if they support Svensmark’s heresy that the Sun alters the climate by influencing the cosmic ray influx and cloud formation.
3) The once illustrious CERN laboratory ceases to be a truly scientific institute when its Director General forbids its physicists and visiting experimenters to draw the obvious scientific conclusions from their results.
4) The resulting publication may be rather boring.
While the results may be boring to some, there is going to be huge uproar in the climate change community if it is clear that that cosmic ray and cause cloud formation. That means that humans have litte or no influence over the earth climate.
