Changes climatic in the Arctic are causing a resurgence of viruses that worry science. The thaw in the permafrost, a frozen layer of subsoil existing in the countries of the Northern Hemisphere, is being thawed due to the high temperature that reaches the place. This change, as scientists advise, can revive “zombie” viruses.
Researchers from Europe found 13 pathogens that were frozen in the ground, located in Russia. In the discovery, they visualized a 48,500-year-old virus that was trapped under the ice, now known as a “zombie”. According to information, this would be the new potential that endangers human life and the lives of animals throughout the world. planet Earth.

Permafrost thawing and virus discoveries
Permafrost is part of a cover that reaches across Canada, Alaska and Russia. It's like a time capsule preservation and scientific field of research. There, ancient viruses and the remains of animals that lived years ago are frozen. The latest discoveries at the site were of a cave lion and a woolly rhino, as scientists report.
Permafrost is a rich field of freezing and not only is it extremely cold, it is also located in a place with no oxygen and no light. The thawing in recent years, caused by climate change, is a concern for the entire planet.
With the discovery, Birgitta Evengard, emeritus professor at the Department of Clinical Microbiology at the University of Umea, located in Sweden, talks about the risk of permafrost thawing:
“If there is a virus lurking in the permafrost that we have not had contact with for thousands of years, it could be that our immune defense is not enough [...] The right thing is to respect the situation and be proactive and not just reactive. And the way to fight fear is to have knowledge”, he warned.
Scientists warn of climate change and melting ice. In Siberia, the thaw faces the highest rates on the entire planet, reaching 38 °C. The local soil remains firm during the summer, but it has not been able to withstand the high temperatures of recent years.
