Record unprecedented 48 ° C in the soil of Siberia | Digital Trends Spanish

Global warming continues to leave unusual and hopeless scenarios. Satellite images recently published by the Copernicus program show that the soil temperature in Siberia exceeded 48 degrees Celsius (118 degrees Fahrenheit) on the longest day of the year.

The highest temperature was measured in Verkhoyansk, located in eastern Siberia. Other areas in the region such as Govorovo reached 43 degrees Celsius (109 degrees Fahrenheit). The highest temperatures since 1936 were reached in Saskylah ((37 degrees Celsius).

It should be noted that the temperatures recorded by the Copernicus satellites of the European Space Agency correspond to the temperature of the earth’s surface, not to air temperatures. The air temperature in Verkhojansk was 30 degrees Celsius. However, high temperatures in the soil can have serious consequences for permafrost.

Permafrost is the permanently frozen layer of soil in very cold or periglacial regions that retains greenhouse gases such as methane or carbon that are released into the atmosphere by increased heat. The release of these gases from permafrost can accelerate this greenhouse effect and cause a situation in which tropical plants on the planet reach temperatures well above the thermal tolerance of humans and many animals and where, in addition, nothing can be grown.

In addition, permafrost has frozen viruses and diseases for which in many cases we are not immunized (such as anthrax, smallpox or bubonic plague) and that could be revived by warming it.
