Climate change is melting Arctic Permafrost, releasing ancient bacteria and viruses, and creating new threats to public health. Virologist Jean-Michel Slavery has spent more than a decade studying the "keystone" viruses found in the Siberian permafrost, some of which are still infectious today. As the Arctic warms, there are growing concerns that more dormant viruses will be released, with potentially dire consequences. The muddy shores of Russia's Kolyma River may not be the prettiest for job. But that's the price virologist Jean-Michel Slavery is willing to pay to uncover the truth about the zombie virus. This is another risk of climate change for public health. This invention revealed the reality of global warming. Earth has been frozen for thousands of years. Calibri, 73, has spent more than a decade studying "giant" creatures, including one discovered 50,000 years ago in the frozen depths of Siberia. Although the world is currently 1.2 degrees Celsius warmer than before the industrial revolution, scientists predict that the Arctic will be ice-free in summer by 2030. Although there are concerns that warming temperatures will melt the region's permafrost and release greenhouse gases such as methane into the atmosphere, the likelihood of contracting the disease is less of a threat. Last year, Cranberry's team published research showing that they recovered many ancient organisms from the Siberian permafrost, all of which were still infectious. Climate change has gotten us used to thinking about weather from the south, Calibri said. In an interview in his laboratory at the University of "AIX Marseille", France, he talked about the outbreak of diseases that originate in the tropics. "We know that there may be dangers from the north due to permafrost, which allows the spread of bacteria, viruses and diseases." The first is still happening. A heat wave in Siberia in the summer of 2016 caused an outbreak of the anthrax virus, infecting many people and killing children and thousands of reindeer. In July, an independent team of scientists published findings showing that even multicellular organisms can survive frozen in harsh metabolic conditions.

The ways in which this can be a threat are still emerging. A heat wave in Siberia in the summer of 2016 activated anthrax spores, causing dozens of infections and the death of one child and thousands of reindeer. In July, another team of scientists published research showing that even multicellular organisms can survive in permafrost in a metabolically inactive state called antibiosis. They were able to revive a 46,000-year-old roundworm from the Siberian permafrost simply by rehydrating it.

It's fundamental from the point of view of being able to stop life and then restart it, says Tiaras Kolcharia, professor emeritus at the Max Planck Institute for Molecular Cell Biology and Genetics, who worked on the study. "It means that it is inherent in some organisms to slow down or stop metabolic processes in some way."

For years, health organizations and governments around the world have been monitoring unknown infectious diseases for which humans have no immunity or drug treatment. In 2017, the World Health Organization added “disease.” Since the coronavirus pandemic shut down the world for months, efforts have only intensified.

WHO spokeswoman Dr Margaret Harris said: The WHO is working with more than 300 scientists to gather evidence for all families of viruses and bacteria that can cause pandemics and pandemics, including which can be released by melting permafrost.

Although hardly related, Calibri's own research occupies similar boundaries. At first glance, the shelves of his research facility, located at the foot of a rocky suburb of Marseille, France, give the impression of a curio shop or the home of an eccentric collector.
