erupting diamonds

23 May 2020

At www.discovermagazine.com/planet-earth/theres-a-russian-volcano-that-erup… … a Russian volcano erupts diamonds. Rather, very tiny diamonds created by crystallisation of volcanic gases. The volcano is actually situated in the Kamchatka peninsular just west of Alaska. Diamonds can get coughed up from deep in the earth – such as the kimberlite rock formations. Generally, diamonds are created by the immense pressure inside the earth's mantle and volcanoes can on occasion dredge them up. These diamonds are nothing like that, so small and hard to detect. Volcanic gases can also form topaz we are told.

Meanwhile, at https://wattsupwiththat.com/2020/05/19/claim-climate-change-killed-the-g… … where we have another anomaly. Australian megafauna seems to hae experienced a mass die off, if not some extinctions, around 40,000 years ago. The date, because it is close to when Aborigines are supposed to have arrived in Australia, together with evidence of landscape fire at the same time, has always been blamed on humans. It  takes a lot of Aborigines to tucker into a great kangaroo. Hence, there has always been scepticism on the validity of this idea. The next most popular explanation is climate change. Academics and scientists studiously avoid catastrophism. The story here comes from www.canberratimes.com.au/story/6760372/giant-kangaroo-victims-of-climate… … and is in that mould, possibly because climate change is currently popular. The comments beneath the first links are therefore dubious simply because it is a climate sceptic web site so they aren't worth reading. Both stories actually radiate from www.nature.com/articles/s41467-020-15785-w … if you want to see all the arguments in black and white. Giant kangaroos and enormous crocodiles disappeared in tropical Australia. Other animals too – such as giant wombats and marsupial lions (in other parts of Australia). We are informed their disappearance coincided with major climatic and environmental deterioration, and evidence of landscape fires. These changes are said to account for the disappearance of the giant kangaroo. However, a catastrophist when reading the account of environmental  change, landscape fire, and a climatic switch, may point a finger at a natural disaster of some kind, one big enough to cause animals to, at least, temporarily die out, if not go extinct. A global catastrophe with a cosmic vector might fit the bill – if one wished to go out on a limb and speculate. The point is that by sticking strictly to what happened in Australia one ignores the contemporary world – and the possibility that it is all interconnected in some manner. For starters, this is when the Neanderthals disappeared from Europe and western Asia, and the Denisovans from various points in eastern Asia (which probably includes Australia and definitely New Guinea, which at the time was connected to Australia). Mass die offs are a feature of different parts of the world at 40,000 years ago, at the end of the Late Glacial Maximum, and again at the boundary of the Younger Dryas event. Lots of catastrophes to get your teeth into there – and there is research available to read on all three events. The relevant article in Nature  has the informative title, 'extinctions of eastern Sahel megafauna coincides with natural environmental deterioration.' Lastly, within the article we are told landscape fires began around 40,000 years ago and peaked in intensity at 28,000 years ago (in the heart of the Late Glacial Maximum). In the Clube and |Napier hypothesis the fire would derive from Tunguska like atmospheric explosions from meteors with an origin in a great comet, or centaur object. There is an extensive literature on the subject.
