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.

Tsunami Mass Burials

At https://phys.org/print452330358.html ... mass burial sites in the Pacific, Mediterranean, and in Scotland were possibly related to catastrophic tsunami waves, according to research published in the Journal of Archeological Method and Theory. Tsunamis are not usually considered when archaeologists are confronted by large mass graves - even on the coast. That is the nature of the beast - catastrophism is generally out of bounds.

Eta Carinae

Sent in by William - bizarre rogue planet discovered wandering in our galaxy - see https://wattsupwiththat.com/2018/08/04/bizarre-rogue-planet-discovered-w... ... a rogue planet without a star roaming the Milky Way just 20 light years away. A study published in the Astrophysical Journal claims it has an incredibly powerful magnetic field 4 million times more powerful than the magnetic field of the Earth. Further, it is able to generate powerful auroras - without the necessity of a sun to send forth plasma plumes.

Black Holes a Bit Stringy

Like a runner bean left on the vine too long black holes are getting a bit stringy - go to https://phys.org/print451826969.html ... black holes are really balls of string - or is it fluff. Black holes are NOT surrounded by a burning ring of fire after all, we are told, but are much more complex. Samir Mathur in the Journal of High Energy Physics invokes Stephen Hawkins and String Theory. What we might take from this is that the preferred version of black hole dynamics is a bit shaky - even in the eyes of fellow theorists.

Sea Level Fall

At https://www.nature.com/articles/d41586-018-05760-3 ... (25th July 2018)an analysis of ancient coral from the Great Barrier Reef in Australia reveals that global sea levels 'fell rapidly' at the end of the last glacial period. The Late (or Last) Glacial Maximum, is dated t its maximum extent between 26,500 and 19,000 years ago and is often thought to represent a prolonged period when glaciation was at its greatest extent. Apparently, this is contradicted by coral growth and retraction in eastern Australia (we are told).

Tall el-Hammam (TeHEP)

There is going to be a National Geographic documentary on Tall el-Hammam in October. One to look out for as astrophysicist Malcolm La Compte is also involved as well as members of a group that took part in LiDAR and multi spectral imaging, photogrammetry and magnetometry, on and around the site of Hammam. The prgramme will focus on the reality and the destruction of Sodom. None of this of course means Hammam is Sodom as there is a good argument to say the Biblical story is an allegory - a ploy to make a point.

Water on Mars

Much ado in the media - water on Mars. However, when you dig into the story the water is a mile deep and unavailable for astronauts to exploit. At https://phys.org/print451740783.html ... an underground lake on Mars, hiding beneath a layer of ice (and even worse, a mile under the surface). The lake is 12 miles wide - and life may exist (bacterial). The water may also be full of salts and minerals making it unfit for drinking purposes.

Brazil in LIA

At https://phys.org/print451717673.html ... isotopic records obtained from caves show how rainfall distribution in Brazil was affected by the Little Ice Age (Geophysical Research Letters, July 2018). They are defining the LIA as AD1500-1850 when average temperatures were lower than at present. In the 17th and 18th centuries climate in parts of Brazil was much wetter - but in the NE is was much drier.

Cold blips in Eemian

This could be classified as geology but is really about climate - palaeoclimate. At https://wattsupwiththat.com/2018/07/23/study-abrupt-shifts-occurred-in-t... ... in a similar vein to the previous post, this concerns abrupt shifts in ancient European climate - courtesy of the University of Helsinki. Big cold snaps occurred right across the Eeemian interglacial (120,000 years ago).

Holocene Geology

At https://phys.org/print451549404.html ... the Holocene is a blink in the eye of geochronology but this has not stopped the grandees fo the International Union of Geological Sciences from dividing it into 3 sections - each defined as a separate geological period. It probably gives their egos a boost but is it justified as the Holocene is littered with climatic downturns and upticks which they largely pass over. True, they have homed in on two very pronounced climatic episodes (which should have geological parallels that are yet unexplored). Why the divisions?
