The Siberian Permafrost Is Cheering Earth Right
Recently, research has revealed that Siberian’s rapidly melting permafrost is changing the landscape by up to 60%. This drastic rate of change is changing the face of the tundra. permafrost thaw will continue to alter the tundra’s surface and will continue to impact regional climate. The melt will open previously unfrosted lakes and rivers, and thaw deposits of ancient forest will also continue to expand. permafrost thawing has implications for a broad range of ecosystems and the global stability. It is projected to result in increased frequency and magnitude of extreme weather events like ice storms and floods.
The Siberian tundra has a large humid layer on its surface, which acts as an insulator against heat and cold. This layer can quickly absorb and store excess moisture from the atmosphere. In summer months, this layer usually thaws and expands, creating an abundant supply of water and allowing surface waters to re-enter the lake and river. However, as winter approaches, this process slows down and the winter chill penetrates further into the soil, creating snow clouds. As permafrost continues to thaw it is projected that the intensity and duration of winter weather will increase.
Global Warming Is Altering the Landscape of Siberia’s Rapidly melting permafrost is changing the landscape of the tundra. One indicator of the change is that in the last 150 years the area of tundra shrubs and grass has declined by up to 40%. This is caused by both the thawing permafrost and global warming. Evidence of global warming can be seen all over the world, on the permafrost, in the form of melt ponds, and in the rising temperatures. With global warming, there is a likelihood of more severe and frequent wildfires as well as other natural disasters that can damage infrastructure and raise the risk of human injury.
As the permafrost thaws, both vegetation and soil will rise
This will cause areas of bare soil to expand and become tundra. The vegetation in these areas will be susceptible to high winds and cold temperatures as they are not adapted to these conditions. Tundra regions will be especially susceptible to pine bark beetles which feed on the leaves of trees.
Siberia’s Permafrost is Affecting Southeastern Siberian Forests The permafrost area of eastern Siberia is particularly at risk due to the extensive amounts of global warming caused by climate change. For this region, permafrost is thawing. The problem is most pronounced in the Kara Sea. The warmer ocean water has thawed and expanded into the tundra, thus increasing the rate of growth of trees there.
Dense Soil This thaw will affect the type of soil and grasses in the region
There will be less grass and shrubs and more weeds. The increase in permafrost will also attract wildlife, possibly decreasing the variety of animals that live in the region. If the permafrost thaws in the southern part of the Kovlevsk region, the soils could erode and spread southward, affecting the arable land.
Siberia’s Permafrost Is Cheering The Earth This thaw poses a threat to the environment as a whole, but is particularly threatening for the massive Siberian tundra. When the permafrost thaws, the soil will rise, eroding hillsides and compacting the earth. The result will be a dramatically changed landscape. In addition, global warming will likely increase the frequency and severity of future global warming due to the increase in atmospheric moisture.
Siberia’s Permafrost Is Changing The Landscape As thawing progresses, the regional tundra will likely be increasingly eroded. The global warming threat posed by permafrost thawing is real, and it’s an issue that scientists have been studying for quite some time. A recent study by the University of Alaska Fairbanks found that permafrost thaw was already impacting the tundra’s ability to absorb the melt that occurs from summertime snowfall. This study is important because it helps us understand how global warming will likely impact this area and the broader environment. We know that permafrost is disappearing from other regions around the world, and it’s only a matter of time before it disappears from the arctic as well.
