Again, it says that my browser is not up-to-date enough to capture the article. You read it. I would think that you could summarize it. Or just copy the summarization and post it. Anyway, here is a rebuttal from climate scientists:
“Scientists involved in related research, however,
doubt the new findings make much difference to accepted climate models.
“The authors need to quantify the effects in an atmospheric model rather than just speculating,” says Ken Carslow, of the University of Leeds, UK, who has also studied potential links between cosmic rays and aerosol formation as part of CERN’s Cosmics Leaving Outdoor Droplets (CLOUD) experiment. “It’s a tiny effect and previous studies suggest it will not be important,” he states.
Terry Sloan, of the University of Lancaster, UK, whose own research has calculated the contribution of cosmic rays at less than 10% of the global warming seen in the 20th century, is also dubious. He points out that other atmospheric “impurities”, such as dust and salt particles, play more important roles as cloud-condensing nuclei.
“The effects [of ionisation] are too small to measure except in the dust- and impurity-free atmosphere such as in their experiments,” Sloan says. “Dust in the atmosphere plays a much bigger part in cloud formation.”
Steven Sherwood concurs. The paper itself, he notes, only suggests the result “may be relevant in the Earth’s atmosphere under pristine conditions”. Even if things do work in the real world the same way as in a laboratory, cloud growth due to ions would only make up “several per cent” of the total.
“Several per cent ain’t much, and the real atmosphere is not pristine,” Sherwood says. While the new research has shown that cosmic rays can produce particles big enough to seed clouds, that was never “the real problem” with Svensmark’s ideas. A bigger issue is the number of such particles, which “would be negligible compared with the background aerosol and the aerosol humans are adding by burning things, tilling soil, etc.”
“If clouds were affected by cosmic rays,” he adds, “they would have been affected a hundred times more strongly by human air pollution, and the world would have cooled over the past century, rather than warmed.”
Henrik Svensmark has propounded a theory of “cosmoclimatology”, which holds that cosmic rays and sunspots are the real drivers of global warming.
