This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Mummified Mammoths and Methuselah Microbes?
One fifth of the Northern hemisphere, has soil permanently frozen for hundreds of thousands of years. As a result of anthropogenic global heating, this permafrost is now melting. This releases trapped methane gas. Methane is a potent 'greenhouse gas', accelerating permafrost melting. Foundations of buildings collapse. The melt also reveals the mummified remains of long-extinct mammals like the Woolly mammoth. Much smaller 'life' forms are also escaping their icy 'tombs'. 'Methuselah' or 'Zombie' viruses may pose dangers to human life (https://www.theguardian.com/society/2024/jan/21/arctic-zombie-viruses-in-siberia-could-spark-terrifying-new-pandemic-scientists-warn). Some of these viruses from the permafrost, are able to infect single-celled organisms (like amoeba) after almost 50,000 years in the ice. Others might be able to infect multicellular organisms. Genetic traces of pox and herpes viruses have also been detected in the permafrost. These viruses have variants that infect humans. It seems entirely possible the next human viral pandemic, will come the permafrost rather than the rainforest!
