Cosmic Rays and Global Warming

This idea that it is all cosmic ray activity which changes cloud over and thus leads to global warming:

Man-made climate change may be happening at a far slower rate than has been claimed, according to controversial new research.

Scientists say that cosmic rays from outer space play a far greater role in changing the Earth's climate than global warming experts previously thought.

In a book, to be published this week, they claim that fluctuations in the number of cosmic rays hitting the atmosphere directly alter the amount of cloud covering the planet.

Not being a scientist obviously, I've no idea as to the truth or not of this. However, worth noting that the various people quoted all seem to agree: there is indeed something to this. The question is, rather, how large is the effect?

This was reported months ago by the Danish space centre

Ah but there's a consensus of 2000 scientists. So clearly this paper must be the work of the oil industry.

This work links cosmic ray activity with the effects of an enlarged solar magnetosphere due to increased solar activity. Now who would of thought that the sun had a part to play in observed global warming?

More to the point, how can we tax it?

Taxation? It's time for a ban on this sort of activity!
