At https://tallbloke.wordpress.com/2024/11/18/scientists-havent-saved-the-ozone-layer-master-resource/ … which is derived from another source. Back in 2015 scientists were predicting the ozone hole would have been reduced by at least half its size by 2020. This was supposed to happen as a result of banning CFC gases in refrigerants. It involved politics and virtue signalling by the great and the good. The Chinese, or some of them, seeing a fast buck in the offing, famously went on producing CFCs in order to collect the payments from Western governments for doing so. The latter turned a blind eye for years. Didn’t want to rock the boat, or look foolish. In spite of the political preening the activists have continued to claim the ban worked. In this post the claim is that in spite of the UN banning CFC gases way back the ozone hole is still alive and kicking, with little evidence it has reduced in any way. Scientists, or some of them, reckoned it would entirely disappear by 2040. Still a few years to go for a miracle. The other important point they make is that it is entirely likely the ozone hole comes and goes as a result of natural forces – unhindered by humans, no matter how clever they think they might be.
The ozone hole has of course declined, and then grown back on several occasions, since the ban came into force. Refrigeration companies have a new set of gases that are supposed to be ozone friendly – but they are produced by the same people and one suspects some commercial skulduggery was at work as the original CFCs had gone over their patent period. Royalties had come to an end. Others have noted a connection with solar activity. At the moment we are in the middle of a solar cycle of eleven years, and at max. The solar wind is known to disperse ozone from the poles as a result of auroral events and so forth. No doubt as we go into solar minimum over the next few years the ozone hole will decline somewhat – as it won’t be dispersed to lower latitudes by heavy solar activity. It will give the impression the hole is actually disappearing – but once we get into a more active period, a few years afterwards, the hole will be back.
At https://www.sciencedaily.com/releases/2024/11/241118125934.htm … we have had a reminder research paper on how 70 per cent of the Mediterranean Sea disappeared between 5.97 and 5.33 million years ago. That is of course uniformitarian numerology. Could the period be somewhat shorter? Something to think about – what might cause the Med to disppear during a catastrophic event?
It was initially promulgated by the discovery of a lot of salt accumulating on what is now the floor of the Mediterranean Sea. It was assumed that ocean water was unable to enter via the Staits of Gibraltar – creating a vast salt desert. At the link we are told there was rapid evaporation – and sea levels dropped. It is then considered that it would have affected terrestrial fauna and flora in the region, as there is evidence of different life forms in the aftermath. The process, they say, was accomapanied by volcanism and tectonic activity that resulted in climate issues. Hence, some life forms died out and others adapted, and new ones appeared. The new study seeks to understand the geological processes that occurred at that time but catastrophism, apart from volcanoes, is not envisioned. It seems the drastic change in sea levels and climate around 6 million years ago is viewed by the effects rather than what actually triggered them.
