Ascientist observes that a region covered by permafrost a few years ago has now thawed. how could this trend be related to the use of fossil fuels?

greenhouse gases trap more heat in earth's atmosphere.

particulate matter covers and warms the ground.

soil thaws more easily as it becomes more acidic.

factories using fossil fuels generate heat.

Greenhouse gases trap more heat in Earth's atmosphere.

Explanation:

Permafrost is the soil that spends the entire year frozen and that covers 25% of the Northern Hemisphere's land surface, mainly in Russia, Canada and Alaska. It can consist of small fragments of ice or large masses, and its thickness can range from a few meters to hundreds.

The greenhouse gases emitted by large corporations through the constant use of fossil fuels, cause the earth's temperature to rise because they promote heat retention. As a result, permafrost can be defrosted. This is very dangerous for humanity because the thawing of frozen soils and can bring back viruses and bacteria that have been trapped in the past.
