Lord Liaden Posted December 13, 2008 Report Share Posted December 13, 2008 Re: Adventure Seed/Hook --- Magnetic Field Failure And Extinction Disrupting the Earth's magnetic field lets in more cosmic radiation? Sounds like a plan by Magneto to induce more mutations. Which, of course, gets out of his control and threatens all life on Earth. Quote Link to comment Share on other sites More sharing options...

McCoy Posted December 13, 2008 Report Share Posted December 13, 2008 Re: Adventure Seed/Hook --- Magnetic Field Failure And Extinction We've got fairly accurate timing (on a geological scale) of magnetic field reversals, and of the extinction events. They don't seem connected. Quote Link to comment Share on other sites More sharing options...
Ian Mackinder Posted December 16, 2008 Report Share Posted December 16, 2008 Re: Adventure Seed/Hook --- Magnetic Field Failure And Extinction 'The Chilling Stars - A Cosmic Vierw Of Climate Change' by Henrik Svensmark and Nigel Calder. A very logical work postulating that a major (and mostly overlooked) factor in the Earth's climate (including ice ages and warm-ups) are the interactions between the Sun's magnetic field and certain forms of extra-solar (cosmic) radiation. Basically, cosmic rays (specifically muons) help stimulate the formation of low-level cloud on Earth by helping produce the particles necessary for nucleation (the tiny things that water needs to condense on in order to form clouds). When the Sun is particularly active (as happened in the 1990s), its magnetic field (which extends past Pluto) strengthens and fewer cosmic rays get through, meaning less cloud cover and therefore warmer, drier conditions. When the Sun gets "lazy", more cosmic rays get through and more cloud cover results. This, plus the background levels of cosmic radiation (which can vary according to local stellar conditions and the Sun's current position in the Galaxy) is a major influence in climate variation. Incidentally, the Earth's own magnetic field is seen as only a minor factor - at least as regards this particular process. Understand that I cannot do the book's line of reasoning full justice here but, as presented , it makes a lot of sense. The book also mentions some of the extraordinarily dogmatic opposition the theory has gotten from the proponents of CO2-based Global Warming (which the authors regard as a fallacy, based on skewed results).
