Hydrogen inside the Earth?

At http://eearthk.com/Articles03.html ... Charles Warren Hunt takes a swipe at the Plate Tectonics consensus theory. He describes it as a hypothesis based on not well tested assumptions. As a result of fawning to one dominant theory alternatives are given the cold shoulder - including the expanding earth hypothesis. This clearly rankles with Hunt but it is worth mentioning the expanding earth idea, and indeed the shrinking earth, were on the table prior to the acceptance of the Plate Tectonics preferred theory of earth dynamics.

Climate Change in the Urals and maps of the bottom of the sea

The Russian Academy of Sciences has produced evidence to show porcupines occupied the Ural Mountains, a generally cool location, during the last major interglacial event. This is one of those strange reports as it is thought temperatures were just a bit warmer than in modern times - but this find indicates it was much warmer. In the Urals, that is. The discovery from a cave deposit and therefore the dating might be conjectural - but it can hardly have been that warm during the intervening Ice Age - could it? The porcupine is an animal of broadleaved forest, not a boreal animal.

Greenhouse Heating to Ice Age ... by Numbers

At www.dailygalaxy.com/my_weblog/2013/01/when-alligators-roamed-the-arctic-... ... foraminifera plankton live and die around the world in virtually every part of the oceans. Immense blooms of marine plankton can actually be seen from space - and when they die their shells fall to the sea floor. Or largely so.

Earthquakes

John Gibson sent in a nice link via www.sis-group.org.uk/contact after reading a post on January 4th concerning solar activity and high magnetised earthquakes. He makes the point others, such as Friedemann Freund and Valentin Strasser have looked at the hypothesis of electro-magnetic coupling, speculating this process may be able to alter the balance present in rocks under tectonic stress and cause earthquakes. The following video comes from a presentation from the SETI Institute 'Living with a star dangerously' - www.youtube.com/watch?v=Ndj85uAHrPg

Scottish fossil raised beaches

Euan MacKie at file://E:\cdrom\pubs\journals\pensee\ivr03\06quant.htm (this is not an external link but a link to the Catastrophism CD - but see also Ian Tresman's web site, www.catastrophism.com) and has the title 'A Quantitative Test for Catastrophic Theories' which is basically an attempt to square C14 dates, as they then were (in the 1970s and 1980s) with catastrophism (of the kind theorised by Velikovsky and his supporters, including the editorial board I suppose).

The Jurassic Climate

At http://phys.org/print276852542.html .... comment on a paper in the journal Paleobiology is somewhat interesting as it seems to contradict some basic consensus science. This is that during the Dinosaur Age the Earth was much warmer than it is today - some geologists even pointing to the Jurassic era as a past example of global warming and how it affected the planet. This is mainly due to the fact it was notably warmer at the Poles - or the geographical Poles as they are now.

Zhoukoudian (Choukutien as was)

The discovery of human skulls and bones amongst a lot of animal bones in a cave near Zhoukoudian (formerly known as Choukutien) near Beijing (formerly Peking) was used by Velikovsky in his book, Earth in Upheaval (on page 55 of the Abacus edition). He said the human remains included Caucasian, Melanesian and Eskimo physical types, three humans washed into a fissure that he claimed was due to a catastrophic event (otherwise unnamed but fairly recent if his discription of the skulls is taken at face value).

Sea Level Changes

At www.CartRuts.com/pages/prehistoricshoreline.html ... there is a nice map of Malta with the shoreline as it was at various times during the Holocene, and showing that in the Ice Age it had been on the end of a peninsular that joined it to the tip of Sicily. This map was produced using recent eustatic sea level prediction methodology of Lambeck (2004) - so it is a model of how it is thought sea levels have gradually risen over time.

Cycles

Chiefio has been looking at Dansgaard-Oeschger and Heinrich events during the last Ice Age - go to http://chiefio.wordpress.com/2012/12/15/d-o-ride-my-see-saw-mr-bond/ ... and in his conclusions says they differ from each other in how the ocean currents shift - and both must happen during a cold ocean regime. They also differ on how cold it is near Greenland when they begin. Bond events happen during a warm ocean regime etc. This appears to mark a major differentiation in the two types of event.

Ice Ages ... a different way of looking at them

Well, perhaps not so different as this paper might be nearly 20 years old, but interesting as Steve Mitchell in his 2004 SIS talk on sea levels around Britain in the Late Roman period toyed with the idea the land had subsided - but can the crust of the Earth move up and down? Well, we have a Swedish scientist that seems to think it can.
