Russia's melting permafrost is truly destroying northern communities. Old Siberian cities like Churapcha are in trouble, as most of the local infrastructure was built on permafrost, which is melting. Per Reuters, roads are in shambles, pipelines are on the verge of bursting, and homes are collapsing as the earth beneath them sinks.
Are Russian cities built on permafrost at risk of collapse?
Russian cities built on the vast permafrost layer that covers the north of the country are at risk of becoming "unstable" by the middle of this century, according to a research paper published in the Geographical Review.
How much of Russia is covered by permafrost?
Roughly 65% of Russia’s territory is covered in permafrost. As air temperatures have risen in recent decades, this soil that has been frozen for millennia has begun to thaw.
Why is melting permafrost so dangerous for Russia?
That's dangerous for Russia because two-thirds of the country rests on permafrost. When it melts, the ground is less solid, and that could be disastrous for cities and critical infrastructure like buildings and oil pipelines. Joshua Yaffa recently wrote about all this for The New Yorker magazine.
What is the biggest threat to Russia's climate?
NPR's Michel Martin speaks with Joshua Yaffa, Moscow correspondent for the New Yorker, about a major climate change threat confronting Russia. While climate policy may be a way to challenge Russia in the future, climate change is threatening that country now. That's especially true of its permafrost, that soil that remains frozen year-round.
How does permafrost affect Russia?
Permafrost is warming much faster than scientists had once thought. That's dangerous for Russia because two-thirds of the country rests on permafrost. When it melts, the ground is less solid, and that could be disastrous for cities and critical infrastructure like buildings and oil pipelines.
How does permafrost affect any settlement built on it?
Infrastructure in permafrost regions is also susceptible to thermokarst processes, which may cause uneven ground settlement and lead to deformation of buildings, economic disruption, and even loss of human life (Nelson et al., 2001. Nature , 410(6831): 889–890.
How does the permafrost affect the geography of Siberian Russia?
Scientists say the craters may be emerging because the frozen ground, or “permafrost”, that covers much of Siberia has been thawing due to climate change, allowing methane gases trapped underground to build up and explode.
What are some effects of permafrost?
CONSEQUENCES OF THE MELTING OF THE PERMAFROSTRelease of greenhouse gases.Release of viruses and bacteria.Damage to ecosystems and their biodiversity.Landslides and geological accidents.
Why does permafrost make developing a town difficult?
When all the water near the surface is frozen into ice, it can make finding drinking water for towns difficult. Many people worldwide live in places with seasonally frozen ground. Hundreds of thousands of people in Alaska, Canada, and Russia live on permafrost (Figure 1).
Can you build roads on permafrost?
A challenge of technology, cost, and a warming climate The bad news is that one of the quickest ways to thaw permafrost is the build a road on it. Permafrost is ground that remains frozen (that is, it stays at a temperature of less than 32°F or 0°C) for more than two years, and in many cases, for hundreds of years.
What will happen when the Siberian permafrost melts?
Siberia's permafrost melt is causing swamps, lakes, making land difficult to live on. The land affected becomes largely useless for agriculture and infrastructure.
What part of Russia is unlivable?
Permafrost occupies nearly 65% of the territory of the Russian Federation. Permafrost is a very common phenomenon east of the Ural Mountains; the extent in the European part of Russia is limited (35).
What would happen if the permafrost melted?
As permafrost thaws, microbes begin decomposing this material. This process releases greenhouse gases like carbon dioxide and methane to the atmosphere. When permafrost thaws, so do ancient bacteria and viruses in the ice and soil. These newly-unfrozen microbes could make humans and animals very sick.
What is permafrost and why is it important?
Permafrost — the permanently frozen ground that underlies much of the Arctic land surface — is thawing in many parts of the Arctic. [1] As permafrost thaws, it releases the powerful greenhouse gas methane into the atmosphere, which contributes to further warming in a reinforcing feedback loop.
How does the permafrost effect climate?
Additionally, organic matter (like the remains of plants) currently frozen in the permafrost will start to decompose when the ground thaws, resulting in methane and carbon dioxide being emitted into the atmosphere. This contributes to further global climate change.
What is currently happening to permafrost?
There is now overwhelming evidence indicating that surface water across permafrost regions is declining. Satellite observations and analysis indicate lake drainage may be linked with permafrost degradation. Colleagues and I have found it increases with warmer and longer summer seasons.
How do you build a house on permafrost?
Driven pilings- A common method for building on permafrost is to drive pilings deep into the frozen ground and elevate the home several feet off the ground. In the village of Atmautluak, for example, the ground has a highly active layer of soil that freezes in the winter and melts in the summer.
How does melting permafrost affect infrastructure?
Degradation of permafrost—perennially frozen ground that often contains subsurface ice—makes it dif9icult to build and maintain infrastructure including roads, buildings, pipelines, and airports. As ground ice melts, soils shift and collapse making the ground unstable thus jeopardizing infrastructure at the surface.
Why does permafrost pose a threat to pipelines roads and settlements?
Permafrost beneath the highway is thawing, causing the terrain to sag. That in turn flexes and distorts the road itself. Some stretches of the highway are now plagued by large cracks in the asphalt. In other places, the road surface has become wavy and irregular, warping as the ground below crumples.
How does melting permafrost impact on Arctic communities?
So, many Arctic communities are built on ground that's becoming unstable, as the permafrost melts. Meanwhile, melting permafrost itself contributes to the problem by unleashing methane and carbon dioxide to the atmosphere, worsening global temperature rise.
What is the result of frozen organic matter in permafrost?
Previously frozen organic matter in permafrost decomposes and generates carbon dioxide and methane.
What causes ice to disintegrate?
Rising temperatures are causing the ice that binds soil, rocks and sand in the ground to disintegrate, setting in motion a process that releases greenhouse gases. Image: Nature.
What is the vicious circle in Russia?
Image: REUTERS/Maxim Shemetov. An environmental vicious circle is taking hold in Russia and other parts of the Arctic as permafrost – the frozen ground beneath a quarter of the Northern Hemisphere and almost 20% of Earth’s landmass – thaws. Rising temperatures are causing the ice that binds soil, rocks and sand in the ground to disintegrate, ...
Is methane increasing?
Methane levels are increasing – and scientists aren’t sure why. It's down to cities to limit global warming to 1.5°C by 2030. Greenhouse gases are bubbling up in Arctic lakes. One of the biggest is a gaping hole in Siberia’s landscape known as the Batagaika crater.
Is the Arctic warming faster than the rest of the world?
The Arctic is warming twice as fast as the rest of the planet, research shows, and longer, hotter summers are expediting the melting process. That’s causing huge areas of land to erode and slide, creating "megaslumps".
How much of Russia is covered in permafrost?
Roughly 65% of Russia’s territory is covered in permafrost. As air temperatures have risen in recent decades, this soil that has been frozen for millennia has begun to thaw.
Does Russia decarbonize?
Russia’s decarbonization strategy heavily relies on the country’s forests to absorb excess carbon emissions, a plan some experts have met with skepticism.
Is Russia warming faster than the planet?
Here’s a look at some of the ways Russia, which is warming 2.5 times faster than the planet, is already being impacted by climate change — and how these processes will only intensify:
Can you add videos to your watch history?
Videos you watch may be added to the TV's watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer.
How does permafrost affect the ocean?
Coastal regions with underlying permafrost are especially vulnerable to erosion as ice beneath the seabed and shoreline thaws from contact with warmer air and water. Though little specific monitoring has yet been done, generally, the projected increase in air and water temperature, reduction in sea ice, and increase in height and frequency of storm surges are expected to have a destabilizing effect on coastal permafrost, resulting in increased erosion. Low-lying ice-rich permafrost coasts are thus most vulnerable to wave-induced erosion. One result of this erosion is that more sediment will be brought to coastal waters, adversely affecting marine ecosystems. Increased coastal permafrost degradation could also result in greater releases of carbon dioxide and methane. Coastal erosion will pose increasing problems for some ports, tanker terminals, and other industrial facilities, as well as for coastal villages. Some towns and industrial facilities are already suffering severe damage and some are facing relocation as warming begins to take its toll on arctic coastlines.
What is the Tuktoyaktuk Peninsula?
The Tuktoyaktuk Peninsula is characterized by sandy spits, barrier islands, and a series of lakes created as thawing permafrost caused the ground the collapse (“thermokarst” lakes). Erosion is already a serious problem in and around Tuktoyaktuk, threatening cultural and archeological sites and causing the abandonment of an elementary school, housing, and other buildings. Successive shoreline protection structures have been rapidly destroyed by storm surges and accompanying waves.
Why is the shoreline of Shishmaref so vulnerable to erosion?
Reduced sea ice allows higher storm surges to reach the shore and the thawing permafrost makes the shoreline more vulnerable to erosion, undermining the town's homes, water system, and other infrastructure. The problem of coastal erosion has become increasingly serious in Shishmaref in recent years.
How will permafrost affect infrastructure?
The effects of permafrost thawing on infrastructure in this century will be more serious and immediate in the discontinuous permafrost zone than in the continuous zone. Because complete thawing is expected to take centuries, and benefits (such as easier construction in totally thawed ground) would occur only after that time, the consequences for the next 100 years or so will be primarily negative (that is, destructive and costly).
What is the reason for the evacuation of Shishmaref?
The village of Shishmaref, located on an island just off the coast of northern Alaska and inhabited for 4000 years, is now facing the prospect of evacuation. Rising temperatures are causing a reduction in sea ice and thawing of permafrost along the coast. Reduced sea ice allows higher storm surges to reach the shore and the thawing permafrost makes the shoreline more vulnerable to erosion, undermining the town's homes, water system, and other infrastructure.
Why do trees die in the winter?
Thus, even if a longer, warmer growing season might otherwise promote growth of these trees, thawing permafrost can undermine or destroy the root zone due to uneven settling of the ground surface, leading instead to tree collapse and death. In addition, where the ground surface subsides due to permafrost thaw, even if the trees do not fall over, these sites often become the new lowest points on the landscape. At least seasonally, these places fill with water, drowning the trees.
What are the implications of the decline of Arctic sea ice?
One impact of the projected increase in marine access for transport and offshore development will be requirements for new and revised national and international regulations focusing on marine safety and environmental protection . Another probable outcome of this growing access will be an increase in potential conflicts among competing users of arctic waterways and coastal seas, for example, in the Northern Sea Route and Northwest Passage. Commercial fishing, sealing, hunting of marine wildlife by indigenous people, tourism, and shipping all compete for use of the narrow straits of these waterways, which are also the preferred routes for marine mammal migration.
What are the effects of forest fires in the Arctic?
Another implication of forest fires in the Arctic Circle is the burning of peatlands, carbon-rich soils that accumulate as waterlogged plants slowly decay , sometimes over thousands of years. These are the most carbon-dense ecosystems on Earth; a typical northern peatland packs in roughly ten times as much carbon as a boreal forest and nearly half the world’s peatland-stored carbon lies between 60 and 70 degrees north, along the Arctic Circle.
What is the Russian Roundwood Act?
The 2013 Russian Roundwood Act requires the timber process to have documentation for Roundwood transportation, logs of valuable hardwoods and Roundwood sales to be declared in an open-source database alongside the implementation of penalties for non-compliance with the law concerning the Roundwood transaction declaration.
How long can forests be licensed?
Forests can only be licensed as concessions to enterprises for one to 49 years, but the Office of the President of the Russian Federation reported an approximate 66% increase in illegal logging from 2008 to 2013 in the Russian Federation. Action to combat illegal deforestation is taken by the Federal Forestry Agency of Russia, ...
Why won't the Forestry Agency extinguish fires?
The Forestry Agency says the authorities will not extinguish 91% of the fires because they are located in “control zones.”. Forests fall into control zones when the fires have no effect on local populations and when the cost of extinguishing them is greater than the residual damage of the fires. “The role of fires in climate change is ...
What is the purpose of export tax in 2008?
Additionally, an export tax in 2008 aimed to restrict log exports, reduce the loss of forest resources and increase domestic processing, jobs, and revenue for the domestic forestry industry .
How much tree cover has Russia lost?
From 2001 to 2019, Russia lost 64 million hectares of relative tree cover, equivalent to an 8.4% decrease since 2000 and 17% of the global total. In 2018 alone, Russia lost 5.6 million hectares of tree cover followed by Brazil with nearly 3 million.
Why is China restricting logging?
Yet China has sharply restricted domestic logging to preserve its own forests, as well as Russian timber facilities to only be staffed by Chinese labour.
