Permafrost is a layer of soil and rock that does not thaw even in summer, but when it does, it creates sinkholes that can reshape Arctic landscapes in a matter of months.
As the ice begins to melt, the rocks and other sediments that were underneath will be visible as swampy, eroded land, also known as thermokarst. Previous research explains how the surface is modeled after permafrost. Permafrost makes up 15% of the earth's soil.
Permafrost regions are found in a polar climate, where the average annual temperature does not exceed -1 ° C, and the average annual precipitation is less than 1000 mm. areas of permafrost are in the polar zone; high mountain areas are covered with glaciers; in these areas there is only sparse tundra vegetation.
As a result of this melting process, carbon is released into the atmosphere, and its amount exceeds the calculated values of specialists. This release can then accelerate global warming, and this cycle is known as climate change. We all know that frozen water has a larger volume than liquid water, so when the permafrost begins to melt, it turns the frozen land of the Arctic into a flooded land that looks like “broccoli soup.”
“This can happen very quickly, causing relatively dry and hard ecosystems (such as forests) to turn into lakes within a few months or years, and the effects can spread to the soil to a depth of several meters,” said Merritt Turetsky, lead author of the study. …
Scientists believe this process plays a significant role in global warming, and perhaps this is one of the many reasons why we no longer have four seasons. Winter will be in March, we will not have any spring. Global warming is a very sensitive topic that affects us all. The main problem is that our ecosystem will soon disappear …
