Why is "Pathogenic microorganisms in frozen environments" trending?

Wikipedia Overview

On Earth, frozen environments such as permafrost and glaciers are known for their ability to preserve items, as they are too cold for ordinary decomposition to take place. This makes them a valuable source of archeological artefacts and prehistoric fossils, yet it also means that there are certain risks once ancient organic matter is finally subject to thaw. The best-studied risk is that of decomposition of such organic matter releasing a substantial quantity of carbon dioxide and methane, and thus acting as a notable climate change feedback. Yet, some scientists have also raised concerns about the possibility that some metabolically dormant bacteria and protists, as well as always metabolically inactive viruses, may both survive the thaw and either threaten humans directly, or affect some of the animal or plant species important for human wellbeing.
