7. What are the bacteria related to permafrost?
Permafrost soils are extensive storage of organic carbon, which have been underground for hundreds of millions of years. Experts have estimated that there are about 1.7 billion tons of organic carbon under frozen deserts, almost double the total carbon in the atmosphere. As long as the soil remains frozen, the carbon is inert, but when the permafrost thaws, the organic matter is transformed into CO2.
This transformation process is due to the activity of bacteria and viruses that have been in hibernation in permafrost soils for millions of years. Once the thawing process has started, due to the increase in global warming, the microbial agents are activated and begin the decomposition of organic matter. The resulting CO2 during the process is released and rises to the atmosphere, being able to considerably increase the greenhouse effect and consequently the temperature on the planet.
