Consequences of Thawing Permafrost

• Thawing permafrost can severely impact the planet. One of its most dangerous consequences is the release of greenhouse gases into the atmosphere. 
• A 2022 report by NASA said, “Arctic permafrost alone holds an estimated 1,700 billion metric tons of carbon, including methane and carbon dioxide”. That’s roughly 51 times the amount of carbon the world released as fossil fuel emissions in 2019
• Plant matter frozen in permafrost doesn’t decay, but when permafrost thaws, microbes within the dead plant material start to break the matter down, releasing carbon into the atmosphere. It could also unleash various dominant viruses and bacteria
• Due to rising global temperatures, thawing permafrost is likely to destabilise thousands of industrial sites and linked contaminated areas in the Arctic region which could result in the spread of toxic substances across the region
• The Arctic is getting warmer nearly four times as fast as the rest of the planet due to climate change, permafrost is thawing rapidly, which could destabilise not only the industrial sites but also the contaminated areas
• There are various industrial wastes (in the region) including drilling and mining wastes, toxic substances like drilling muds and fluids, mine waste heaps, heavy metals, spilled fuels, and radioactive waste

Conclusion

Your concluding remark should be short and should encapsulate both parts of the answer

A thawing permafrost layer can lead to severe impacts on people and the environment. For instance, as ice-filled permafrost thaws, it can turn into a mud slurry that cannot support the weight of the soil and vegetation above it. Infrastructure such as roads, buildings, and pipes could be damaged as permafrost thaws
