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.

supernova and life on earth

At https://phys.org/print445854431.html ... could recent supernova explosions be responsible for mass extinctions - or some mass extinction events to be more precise. The story is in NASAs Astrobiology Magazine at www.astrobio.net ... In particular two lesser known extinction events (or part extinction events as opposed to globally significant events), at 2.5 and 8 million years ago. The idea being put out to fellow scientists is that supernova explosions may have depleted Earth's ozone layer. The one at 2.5 million years ago coincided with the end of the Pliocene era.

Shaking the Heavens

The idea of gods shaking heaven and earth is not only found in the Bible (the words of the prophets and psalms) but is fairly common amongst most people of the ancient near east - including what is now Iraq - see https://phys.org/print443688956.html ... It is common to Enlil and Ninlil, Enki and Ninhursag for example, and more or less concerns trickery, shape shifting, disguise, and deception. As the consort of Yahweh is absent from the Bible as it now stands one has to wonder if the same thing applies to ancient Israel - but see William Dever's book.

Mass extinction events and dinosaurs

At https://phys.org/print443093224.html ... not only were dinosaurs eliminated by a catastrophic event at the K/T boundary 66 million years ago but they evolved into a successful species after the Permian mass extinction event 245 million years ago. Now we are being told but dinosaurs were but one of several successful species for around 13 million years - until another extinction event, 232 million years ago. After this event dinosaurs were able to expand very quickly. It is known as the Cernian Pluvial Episode.

Arctic Ice Shelf

An article in Nature Communications (April 2018) suggests that a Eurasian ice sheet did not extend into the Arctic Ocean during the Late Glacial Maximum. This is distinctly different to an earlier glaciation event where an ice shelf larger than Greenland once existed in the Arctic Ocean, so big it has left its evidence of existence on the sea bed - particularly on the Lomonosov Ridge. Scour marks from glaciation seem to show the ice shelf rested directly on the sea bed - much like the Greenland glacier of today.
