They are thought to be associated with natural instabilities, or tipping points in climate change rhetoric. This is mostly because any other explanation seems to be less likely.

Whether this included traders in the Roman period or not it unclear but it certainly did in the Islamic ascendancy between the 6th and 13th centuries AD. As such, Ghana was keyed into a massive trade network from China and Indonesia to Spain, a network of trade routes.

Cooking leaves behind a residue that modern science can translate into what was being cooked - even though those pots, usually found as sherds, may be thousands of years of age. This is a remarkable achievement in itself and a scientific tool unavailable to earlier archaeologists. It all comes at a price of course and the sponsors of any dig must have the funds to pay for it, and C14 dating. In other words, not something your low funded communal type dig could afford.
This story is crawling all over the Internet this week and see http://popular-archaeology.com/issue/winter-2017/article/archaeologists-... ... which is a bit of a non story as all they appear to have done is come up with two sets of dates when things went wrong for the Maya. Instead of a gradual decline, as in previous studies, the contention in this research is that it occurred primarily at two points in time (possibly by narrowing down C14 methodology to tweek the specifics).
Carl Sagan didn't always get an enthusiastic hearing in Velikovskian circles as he was prepared to publicly criticise some of his ideas. However, he didn't dismiss them in a pompous manner, or one of contempt. Neither was he particularly the bogey man he was depicted by some people.
Creation Science has a bright future according to Dr Wile - go to http://blog.drwile.com?p=15572 ... and the link concerns a recent panel event where a team of creation scientists took questions from a large audience, said to include scientists with some probing questions. One of his fellow panellists was John Sanford, a geneticist, the inventor of the 'gene gun' (a device to introduce DNA from one organism into another organism).
Worlds in Collision is becoming quite a popular theme in modelling circles. Gary sent in the links below. At www.dailymail.co.uk/sciencetech/article-4149746/Early-Earth-scarred-mass... ... a massive bombardment event occurred 4 billion years ago and this involved disintegrating failed planets smashing into each other and causing debris to fly around the solar system.
At https://phys.org/print404412354.html ... apparently the Pueblo people of the American SW used geometry in the design of their pueblos. Not only that they used a standard unit of measurement, around 30cm in length (very close to a modern foot). How times change. Back in the 1980s Alexander Thom was ridiculed for claiming the stone circle builders used a standard unit of measurement that he called the Megalithic Yard. He was also laughed at for suggesting they also used geometry to produce ovoid circles.
Some upside down thinking at Scientific American - the result of a CAGW driven editorial agenda. Why is China dominating the global manufacture of solar panels? See https://www.scientificamerican.com/article/why-china-is-dominating-the-s... ... which concludes the Chinese are good guys and are coming round to the CAGW point of view - in spite of the fact they are still building large numbers of coal fired power stations. It all sounds a bit like their adherence to the ozone hole a few years ago.
In the same issue of World Current Archaeology 81 we learn that at the Warrutyi rock shelter 55km north of Adelaide, in the Flinders Ranges, a local Aboriginal elder and a researcher from La Trobe University, when surveying a remote gorge peered into the shelter and noticed it had a fire blackened roof. This was the sort of site they were interested in as it suggested a long period of time with endless camp fires.
