Geological Instant

At https://www.eurekalert.org/pub_releases/2018-09/caos-cts091718.php ... we have an interesting headline - Chinese led team (from the Chinese Academy of Sciences) shows mass extinction happened in a geological instant. Of course, what they mean by a geological instant is nothing like the real meaning of that word. They are claiming the end of Permian mass extinction event took place between 30,000 years ago and a few thousand years ago (leaving an option open for an even smaller instant in time). The end of Permian event took place around 250 million years ago.

Ancient Mexican Monsoon

At https://phys.org/print455182676.html ... analysing traces of leaf wax from local plants that accumulated in sediments in the sea by a team of researchers at the University of Arizona have reconstructed a history of monsoon activity in NW Mexico  and SW United States. The research was published in Nature Geosciences (Sept 3rd 2018) and shows that monsoon activity did indeed continue during the Late Glacial Maximum - but at a reduced level. Monssons divert moisture from the tropics and bring relief to long hot summers in the arid zones (above).

K/T boundary event again

This subject was sent in by several people including Jovan and William but Robert has gone straight to the source of the sauce in an article at www.theatlantic.com/magazine/archive/2018/09/dinosaur-extinction-debate/... ... the controversy over the K/T boundary event in which both sides have had an acrimonious relationship since the Alvarez theory was adopted as mainstream science. That is the gist of the article - but is there a political angle the magazine is trying to push? As I don't read The Atlantic I have no idea.

Facts and Fictions

At https://phys.org/print452150037.html ... a carbon leak may have warmed the planet beginning in around 11,000 years ago, encouraging human civilisation to develop. The oceans are the planet's liggest depository of atmospheric carbon dioxide - so how do you get to releases lots of co2 and warm the planet (assuming co2 actually has a warming effect in the first instance). Well, according to this study, activity in the Southern Ocean was responsible - pulling out of the hat a hoary old chestnut in respect of the ocean current circulation.

Revelations

Sent in by William. Interesting take on Revelations, the last book of the Bible. Trumpet judgement 1 includes a meteor or bolide, no 2 refers to a large meteor, no 3 a huge bolide, no 4 astral observation, and no 7 a great hail of stones. These ideas are expressed in 'Revelation: What Did John Really See?' by Phillip J Silvia ISBN 9780615866055 and available via www.biblicalresearchbulletin.com ... and presumably via online bookshops.

Antique CAGW

At https://malagabay.wordpress.com/2018/06/22/late-paleocene-thermal-maximum/ ... here we have a catastrophic event that has been apprehended by climate scientists in order to create a scare story over CAGW. The late Paleocene/Eocene boundary event is supposed to be a classic case of the earth over heating. As you might expect the CAGW adherents have proposed there wasa lethal injection of carbon dioxide into the atmosphere in order to account for the rise in temperatures.

Genetic Bottleneck

This one was sent in by Jovan - go to www.livescience.com/62754-warring-clans-caused-population-bottleneck.html .... males genes across Asia, Europe and Africa seem to suggest something peculiar happened between 5000 and 7000 years ago (or 3000-5000BC) in which women were left numbering 17 to 1. Obviously, this can't be strictly true unless it was a mutation of some kind (lucky fellas if that was the case). The idea of a male bottleneck at this point in time was first raised by researchers in 2015 and since then scientists have been trying to make sense of it all.

Warmish Greenland

At www.sciencedaily.com/releases/2018/06/180604151150.htm ... the preservation of flies in mud on Greenland show that two interglacial periods witnessed a warming of the climate close to the modern ice sheet. Temperatures were somewhat warmer than today - and this is projected to have been significant. Lake muds that survived the last Ice Age (its entirety) has the remains of common flies.

Jurassic Sea Flood

At https://phys.org/print447399984.html ... dinosaur age marine fossils have been found in the middle of Australia - hundreds of miles from the sea. They are micro-organisms known as dinoflagellates which produce red tides (algal blooms). It is thought Australia was still attached to Antarctica at the time, which adds to the mystery. Interestingly, in the succeeding Cretaceous period there is evidence of a vast inland sea in Australia - but the new evidence comes from the Jurassic.

K/T boundary event

Sent in by Jovan (as the earlier link to Sky and Telescope). Global warming caused by co2 levels reaching 2300 parts per million. Currently we have just over 400 parts per million and alarmists are feeling very wobbly. WEhat researchers have found is that after the K/T boundary event temperatures shot up - in North Africa. One might suppose an asteroid strike would cause global cooling due to lots debris in the atmosphere - and the researchers acknowledge this. They claim it was followed by a period of global warming which lasted for 100,000 years.
