There are a couple of emerging theories on clouds, and how they form, and in time these theories may blow away the current so-called consensus on anthropogenic global warming from carbon dioxide as a key driver of climate.
One of these theories concerns cosmic rays.
A couple of weeks ago I mentioned the words “cosmic rays” with some enthusiasm at a Sunday lunch and everyone looked a me with a degree of apprehension and no one asked me to “explain further”. I could see the minds of the 10 or so others at the table ticking over. They were probably thinking, “What on earth is she talking about?”.
Well, I was about to attend a lecture by Dr Eigil Friis-Christensen, the director of the Danish National Space Centre.
This centre has published research suggesting that satellite observations of cloud cover and laboratory observations of aerosol formation indicate climate is signifcantly affected by the cosmic ray flux, modulated by the solar magnetic field.

Current United Nation’s IPCC climate models do not incorporate the influence of cosmic rays and therefore according to Dr Friis-Christensen can not hope to predict future climate.
The week before Dr Friis-Christensen gave his lecture at Mittagong, a paper was published suggesting the potential influence of cosmic rays was over-rated. Bloggers Lubos Motl and Nir Shaviv discuss the problems with the Sloan & Wolfendale paper which was given significant exposure by the BBC.
