This is the third link that is reminiscent of Malaga Bay (remember the black smokers on the ocean bottom) - see http://phys.org/print303899664.html ... a paper in Nature Geoscience by a team from the Norwegian Geological Survey claims oxygenation of the atmosphere and oceans came about two billion years ago. This also produced phosphorous - and phosphorus was the clue to the findings. Phosphorous is an important ingredient of life and all this popped out when the team were looking at rocks in Karelia (next door to Finland but in Russia) reputed to be two billion years of age.
Malaga Bay also came to mind when I read the headline here too - see http://phys.org/print304016779.html ... microbiologists have found that methanogen microbes can reduce carbon dioxide to methane by a mechanism in which they make 'electrical connections' with other micro organisms, something not recognised in methanogens before. Bacteria anaerobically digest biomass to produce methane gas, an important piece of bio-energy. In nature these methanogens are active in bogs, swamps, and wetland zones, and their productivity is a source of angst to climate alarmists.
I couldn't help thinking of some of Malaga Bay's postings when coming across this at http://phys.org/print303991846.html ... a piece of research on amber deposits. A team of sicentists have analysed modern and fossil resins and the results seem to suggest there was less oxygen in the atmosphere in the geological past than previously imagined. The study therefore raises a question mark about current theories on the evolution of climate and of life itself, including the causes of gigantism in dinosaurs.

He then quotes Wikipedia extensively on a number of subjects - and you've guessed it, he finds contradictions. He adds to that, 'glaciology stinks ...'
At www.pasthorizonspr.com/index.php/archives/09/2013/genetic-link-shown-bet... ... a paper published in PLoS ONE, using DNA methodology, has shown a fairly stable population in Syria and the middle Euphrates valley right up to the Mongolian invasion in the 13th century. At this time so many people died the genetic makeup was altered. On the face of it, this ignores the role of the Black Death in the 14th century - so perhaps both events should be flagged up.

This particular study, published in PLoS ONE, concentrates on the archaeology of Cyprus.
At www.spaceweather.com ... Comet ISON is getting brighter and brighter as we approach the end of November encounter with the Sun. Its tail now extends 8 million km behind the nucleus - 21 times the distance between the Earth and the Moon. Not as fantastic as some of the historical comets - but enough to get astronomers fairly excited.
