On the same theme as the piece a few days ago on carbon dioxide, William sent the following link to a piece published in the Boston Globe. See https://www.bostonglobe.com/opinion/columns/2017/03/14/why-are-climate-c... ... the opinion is that of 'Jacoby on Climate Change'
At https://phys.org/print408881453.html ... getting to the crust of the early earth is not easy as it has been overlain with a raft of later layers leaving it deep and difficult to access. Geologists from Carnegie and the University of Ottawa decided the Canadian Shield was the place to go as it was wiped clean during the Ice Age. They purportedly found crust that was 4 billion years of age along the eastern shore of Hudson Bay.
Robert sent in the link, http://crev.info/2017/03/rethinking-fossils/ ... where we have more new fossil discoveries that appear to be counter to uniformitarianism. The first batch of fossils come from China, sponges that date shortly after the Ordovician Extinction event (already reviewed on the News) and an early fish which was also discovered in China and apparently dates from before the Devonian. He claims the Devonian is the Age of the Fishes and therefore to find an example before that is anomalous. It may be but it also may not as it simply shifts fish evolution backwards.
At https://tallbloke.wordpress.com/2017/03/15/auroras-affect-sat-nav-system... ... This is an interesting one as aurora are produced when gas particles in the Earth's atmosphere collide with charged particles emitted from the Sun. The resulting plasma turbulence has long been thought to be the reason why global navigation satellite systems go awry. New research casts doubt on this view.
At https://phys.org/print408702531.html ... we have a strange paper here - but useful in the sense it provides another dimension to what is normally pushed our way. It concerns the drying up of the Sahara desert. Were humans to blame?
More on the feeding habits of black holes. This one is choking on the amount of material in its gullet - see https://phys.org/print408783134.html ... The paper was published in the Astrophysical Journal Letters but the press release comes from MIT. What was recorded was a 'tidal disruption flare' (see earlier post on the subject) which is basically a dramatic burst of electromagnetic energy. This is thought to occur when a black hole shreds and digests a passing star.
At www.dailymail.co.uk/sciencetech/article-4312926/Mysterious-space-object-... ... straight from the horses teeth, the source that Wikipedia refuses to accept as reliable. As they don't accept SIS as a serious society we have more than a little sympathy for the Mail. Their science stories come straight from science papers and university press releases, but that is not what the Wiki gestapo object to. It was a couple of articles by David Rose that fingered the CAGW cheats and claimed there was dodgy goings on.
Wiki has a good piece on the Piora Oscillation, the official name for the period of global cooling that followed on from the 3200BC event. It lasted for 200, maybe 300 years in duration and divides the Pre-Dynastic phase from Dynasty One. In Sumeria it marks the end of the Uruk phase with a confused episode dividing it from the Early Dynastic Period. There is plenty of evidence to suggest horse mounted barbarians arrived from the steppe zone at this time - including the Royal Graves of Ur which mimic the kurgans that littered southern Russia and western Siberia in the 4th millennium BC.
At http://www.msn.com/en-us/news/opinion/scott-pruitt-is-absolutely-right-a... ... link sent in by William. One of Trump's fake news channels seems to have come up trumps by publishing this piece of analysis regarding other media outfits. The interview by CNBC of Scott Pruitt the new head of the EPA went hyper at a host of media stations and newspapers. He is contradicting global warming science and that kind of stuff.
The latest piece of modelling a black hole is said to show a black hole can grow rapidly at the centre of a host galaxy if a nearby galaxy emits enough radiation to switch off its capacity to form stars. See https://phys.org/print408627219.html ... the collapse of the galaxy and the formation of a million solar mass black hole toakes100,000 years - a mere blip in cosmic time. A few hundred million years later it will have grown into a billion solar mass supermassive black hole.
