The lunar dynamo model?

At www.dailygalaxy.com/my_weblog/2013/01/the-moon-was-once-powered-by-a-dyn... ... it seems scientists have found evidence that rocks on the moon were magnetised millions of years ago. This discovery has led to the idea the moon formerly had a metallic core that produced the magnetic field - a lunar dynamo. It is thought a dynomo exists at the heart of the Earth.

The Earth in an electric solar system

The Earth in an electric solar system is a paper by Louis Hissink in the New Concepts in Global Tectonics Newsletter, a link forwarded by the contacts tab by member Robert Farrer, and you can find it by going to www.ncgt.org and scrolling down to issue 51, clicking on and downloading the full pdf of that issue. Once downloaded you pick which pages you might want to print out. This paper is fairly short in comparison to some of them.

The Solar System Dynamic Theory of Climate

Tall Bloke is suggesting we shove global warming somewhere on the dark side of the establishment. At http://tallbloke.wordpress.com/2013/01/18/inaugural-conference-2013-the-... ... anyone interested in the connection between the Sun and climate on earth, the sort of thing practised by Piers Corbyn at www.weatheraction.com might like to attend this conference, upcoming in September of 2013, at the University of Leeds. This is where Tall Bloke works, in IT, and hopefully there will be some cutting edge science on the table.

Plasma UFOs

A new web site for people into electro-magnetic effects, ionised atmospheres, and plasma physics - go to http://hozturner.blogspot.co.uk/2012/09/towards-natural-plasma-explanati... .... which begins with UFOs and the possibility they are plasma related and then digresses to ionised atmospheres, lightning and plasma, and Birkeland currents etc., with lots of images, videos and other links.

Sun and the Weather

In Sun, Weather and the Climate, John Herman and Richard Goldberg, the two authors, explore meteorological variations related to solar activity and the physical linking mechanisms that may explain the relationships. Several new mechanisms are brought to the table, as well as experimental concepts. The authors reasoning is that in spite of a large literature on the subject there remains widespread disbelief, especially amongst climate scientists.

Sun/Earth relationships ... what was thought about it in the 1970s and 1980s.

Some years ago I purchased a slim volume, Reversals of the Earth's Magnetic Field, expecting some information that might bear on the subject Peter Warlow was researching. It didn't prove much help at the time but I have now had a second look at it. Written by professor JA Jacobs of Cambridge University (and formerly of the University of British Columbia) it was originally published in 1984. It is still available second hand on the ABE book site - simply log in the ISBN number, 0-85274-442-0.

Solar activity and high magnitude earthquakes

Robert Farrar sent in this link to the Journal of the New Concepts in Global Tectonics - go to www.ncgt.org and click on 'issues' and then click on 'issue 65' (December 2012). You can convert the file to PDF format but you will find there are over 154 pages to the journal, a formidable printing project. Simply press the pdf to print button, click on pages (delete 1-154 and convert to 6-34) and you will have a print out of three excellent articles on solar activity and hypothetical connections to earthquake activity.

A cosmic ray attack on the Earth

Leading on from the previous posting this story comes from www.dailygalaxy.com/my_weblog/2012/12/-december-27-2004-the-day-planet-e... ... which sounds a bit over the top - and probably is. You may not have realised that on December 27th 2004 something so dire occurred but apparently a burst of energy equivalent of half a million years of sunlight was directed at the Earth, a gamma ray burst that ionised Earth's upper atmosphere. The source was in the region of the sky occupied by the constellation of Sagittaurus.

Cosmic Rays

At http://phys.org/print275845800.html ... cosmic rays are thought to originate in massive stars somewhere out in the universe, tiny particles that rain incessantly down from space. Victor Hess, around about a 100 years ago, established during a high altitude baloon flight that the radiation was cosmic in origin. Later, it was suggested the radiation might be gamma rays, an idea that has stuck. These are high energy electromagnetic radiation. Later, it was found the incoming rays were influenced by Earth's magnetic field implying they were charged particles.

Ionosphere of Venus

At http://phys.org/print275843816.html ... NASAs Pioneer Venus orbiter, as long ago as 1978, suggested the ionosphere of Venus had a magnetised state with a large horizontal magnetic field but at other times it was, apparently, unmagnetised with no obvious large magnetic field. Instead, it is thought, or was, it had numerous small magnetic structures known as flux ropes and it was the polar wind, or Venus facing sun spot eruptions, that caused it to have an obvious magnetic state.
