At https://phys.org/news/2024-09-uk-ireland-climate-tropical-million.html … we are told that 26 million years ago the climate in the UK and Ireland was tropical. The assumption is the globe, as a whole, was also warmer and wetter. By reading layers of rocks we can travel back in time, we are assured. In studying the fossils in those rocks we can reconstruct ancient climates. So far so good – but the rest of it is alarmist spinning.
Getting our feet back on the ground – at https://phys.org/news/2024-08-salt-giant-radically-reshaped-mediterranean.html … here we are back iu the late Miocene, 8 to 7 million years ago. Marine animals in the Mediterranean attest to the presence of numerous organisms. Scientists are looking to understand how marine biota were impacted by the salinisation of the Mediterranean. The evidence points to a crisis in the Mediterranean following the arrival of salt water. Only 11% of the biota survived the crisis – and it seems to have taken 1.7 million years to recover. This yawning number is hard to accept. It is arrived at by dating sedimentary rocks via the uniformitarian dating system that is central to geochronology. The ecological crisis smacks of catastrophism – and the fact we are talking about an influx of salt one might wonder if there was a giant wave or wall of water that crashed through the entrance of the inland sea. The mainstream view is that the Mediterranean shrank, leaving a huge deposit of salt. This is not the only salt giant in the world as underneath the North Sea there is a thick layer of salt from an earlier era. Salt giants also exist elsewhere in Europe, and in Australia and Siberia etc. The origin of these layers of salt is open to reinterpretation. However, they have been a welcome resource to humans. We have salt mines in Pakiststan and at Hallstatt in central Europe, for example. The Mediterranean salt giant is a kilometre thick layer of salt beneath the sea and is thought to have formed when the entrance to the inland sea was subject to configuration in a period of temperature fluctuations. Later, when the entrance was open again it allowed entirely different biota to colonise the Mediterranean. See also https://doi.org/10.1126/science.adp3703 …
At https://phys.org/news/2024-08-doughnut-region-earth-core-deepens.html …. we now have a doughnut shaped region inside the Earth’s core to match the doughnut surrounding the Earth in near space. Is there a connection? It seems it sits parallel to the equator and appears to slow down seismic waves. What would happen if the equator moved as a result of a shift in Earth’s dipole. Would the doughnut move also? See https://doi.org/10.1126/sciadv.adn5562 …
