Talk:Cloud condensation nuclei

Shouldn't the article mention the (proposed) relationship between cosmic rays and cloud formation? I created a stub at Scientific uncertainty, and the first google hit I found said led me to solar variability, solar wind, and a 2002 peer review paper. It hypothesized that "the cosmic ray-induced global cloud changes could be the long-sought mechanism connecting solar and climate variability". 

Is this old news, i.e., a hypothesis which has already been disproved, or what? --Uncle Ed (talk) 18:03, 5 January 2009 (UTC)


 * Its still very uncertain, ythough tending towards "no", but its discussed best at Cosmic_rays I think, so have linked it. Sorry you had to sacrifice SU to get it :-( William M. Connolley (talk) 21:15, 5 January 2009 (UTC)


 * With this being wikipedia and all, unless there's consensus concerning the issue, we'd have to lean no for the time being. If it ever gets greater support, that would all change of course.  Thegreatdr (talk) 23:35, 5 January 2009 (UTC)


 * It is relativity old news, and has been disproved for recent times. If you read Recent oppositely directed trends in solar climate forcings and the global mean surface air temperature from the Royal Society you will see that this is not a cause of global warming.  You can also read synopses of the article at New Scientist - Sun's activity rules out link to global warming, Telegraph - Sun not responsible for climate change, Guardian - New analysis counters claims that solar activity is linked to global warming, and BBC - 'No Sun link' to climate change.  --Shagie (talk) 23:38, 5 January 2009 (UTC)

Merge to atmospheric particulate?
There is so little information here, is it worth merging this to Atmospheric particulate matter for now?--NHSavage (talk) 18:50, 21 July 2012 (UTC)
