Further responses to Svensmark's paper

At Tall Bloke's Talk Shop, http://tallbloke.wordpress.com/2012/04/24/the-connection-to-evolution-is... .. is a post by Tim Channon and begins by going through the basics of the paper, Earth bombarded with radiation from stellar event as the solar system travels through the Milky Way - and this is linked to paleo history etc. Some similarities exist with a 2005 paper by Gies and Helsel, 'Ice Age epochs and the Sun's path through the galaxy' which is an interesting correlation (see http://iopscience.iop.org/0004-637X/626/2/844/pdf/61945.web.pdf ). The solar system crossed four spiral arms over the last 500 million years and these seem to correspond to long duration cold periods on Earth. This supports the idea that extended exposure to higher cosmic ray flux can lead to increased cloud cover and long ice age epochs. See also Lucy Skywalker and http://larouchepac.com/node/21222 ... and it is worth recalling that Clube and Napier used the passage of the solar system through the spiral arms in their book, The Cosmic Serpent (Faber and Faber: 1982) to account for various setbacks in the paleo record.
