How Does Global Warming Affect Permafrost

Globally, climate change is transforming the face of the planet in unprecedented ways. One of the most significant impacts of global warming is the thawing of the permafrost, a frozen layer of soil and rock found around the world in the Arctic and sub-Arctic regions. The thawing of permafrost presents a number of challenges for plant, animal and human populations, with potential consequences for biodiversity, infrastructure, and the global climate system as a whole.
Permafrost is a naturally occurring layer of frozen soil and bedrock that compose the topmost layer of the Earth’s surface. It spans much of the Arctic and alpine regions of the world, including Alaska, Greenland, Siberia, and portions of the Canadian Arctic Archipelago. Permafrost is typically composed of shallow, discontinuous layers of ice, soil, and rock, and is distinguished by its ability to remain frozen throughout the year, even in high temperatures.
In recent years, the thawing of permafrost has been one of the most concerning outcomes of global climate change. As temperatures rise, permafrost thaws faster and more extensively than before, resulting in destabilization and inundation of local communities, ecosystems, and infrastructure. The process of thawing can be further accelerated by human-induced activities such as industrial burning of non-renewable resources and subsequent ground level emissions, as well as land reclamation projects.
One of the most damaging ecological effects of thawing permafrost is the release of previously stored carbon which can lead to increased greenhouse gas emissions and accelerated global warming. Thawing and melting permafrost releases methane and carbon dioxide from once-frozen lands, which can contribute significantly to atmospheric concentrations of both gases – over a relatively short timeframe. In addition, thawing permafrost can lead to disruption in the availability and quality of safe drinking water, flooding of urban and rural areas due to the melting of surface ice, disintegration of slopes, and erosion of coastline. Wildlife in the area is also affected, as the ecosystem undergoes a drastic shift.
Although the consequences of thawing permafrost are varied and far-reaching, the global community is working to mitigate them. Governments, non-governmental organizations, and independent scientists are working together to implement strategies that aim to lessen the impacts of global warming on permafrost thaw. For example, the Alaska State and Local Energy and Sustainability Working Group is researching methods for adaptation of local infrastructure and resources to counteract the effects of climate change within vulnerable Alaskan communities. In addition, several environmental organizations and universities are researching alternative energy sources that are alternatives to fossil fuels and more sustainable.
The thawing of permafrost as a result of global warming has created a great deal of discussion and debate. Scientists are working diligently to both understand and address the impacts of permafrost thaw on global climate and environment, with new research and policies being developed regularly. It is clear that in order to succeed in avoiding the worst of what the global climate crisis can bring, the global community must continue to come together and take decisive, long-term action in favor of a more sustainable and healthy future.
As individuals, there is much we can do to contribute to the mitigation of the effects of global warming, from reducing our own emissions to advocating for stronger climate policies. Every person must take responsibility and use their voice to amplify the imperative to take actions which will protect the planet and its inhabitants from further warming and destruction. Doing so lies not just in our collective interest, but in our moral obligation as global citizens.
