#Siberia: Residents stunned after strange new formations appear across remote landscape: 'The landscape has become pockmarked'

"Thawing ground in Siberia's remote #YamalPeninsula is warping the landscape — and residents say the changes are becoming impossible to ignore. Strange mounds, sudden sinkholes, and even explosive craters are reshaping the #tundra, alarming locals and researchers alike, per the Malay Mail.

"These changes are tied to a disturbing trend beneath the surface: the rapid thaw of once-frozen ground, known as #permafrost.

What's happening?

"As Siberia warms at nearly four times the global average, vast stretches of permafrost are thawing. When this frozen ground melts, it releases methane gas from ancient organic material once safely locked beneath the surface.

"In the Yamal region, that gas is pushing the earth upward into large mounds that sometimes explode, tearing open the landscape and leaving behind deep craters.

"Innokenty Poselsky, who bought land in Churapcha, noted that he had about 20 mounds pop up but that it wasn't always like that. 'About 40 years ago, there was an airstrip here and the land used to be quite flat. Over the last four decades, the landscape has become pockmarked. It's like that everywhere here,' he told the Malay Mail.

"Local villagers, many of whom rely on the tundra for #reindeer herding, say their homeland has become nearly unrecognizable. One herder told researchers that familiar flatlands have been replaced by unpredictable swells and holes.

Why is the thawing of Siberia's permafrost important?

"Beyond changing the physical landscape, permafrost melt poses major threats to communities and the planet. Thawing ground can damage roads, #pipelines, and homes. #Methane, the gas being released, is over 80 times more potent than carbon dioxide in the short term. That means this process isn't just a local hazard — it's a global #climate risk.

"Thawing permafrost can also accelerate other problems. Warmer, wetter conditions can spread disease, disrupt food systems, and increase the severity of #ExtremeWeather events by adding more heat-trapping polluting gases to the atmosphere.

"While extreme events such as #wildfires and #floods aren't new, scientists agree that a hotter planet — caused by human activity, mainly the burning of #FossilFuels — makes them both more destructive and more frequent."

Late summer in Katmai National Park.
During this time in early September, the tundra comes alive with a psychedelic wave of color. Everywhere you look you are surrounded by undulating layers of reds, oranges, yellow and green.

Most of these small plants grow berries, and in this shot there are over 10 species of berries that I can see.

We were camped here for a week and got absolutely pounded by rain and wind, and on our last day it opened up and we went exploring. Hiking up that snow kissed peak in the background and then we dropped down through miles of tundra to a double waterfall that we had spotted on our flight in. Such a beautiful place, can’t wait to go back.

World's oldest #juniper shrub discovered in #Finland—rings suggest it's 1,647 years old phys.org/news/2025-02-world-ol

Common juniper, the oldest nonclonal woody species across the #tundra biome and the European continent esajournals.onlinelibrary.wile

"the juniper started its growth at #Utsjoki in 260 and died in 1906... It is the oldest shrub in the world and the oldest woody plant in Europe dated by annual rings... #junipers allow scientists to study #climate variations, exceptional #weather events etc."

Groundwater in the Arctic is delivering more carbon into the ocean than was previously known

A relatively small amount of #groundwater trickling through #Alaska's #tundra is releasing huge quantities of #carbon into the #ocean, where it can contribute to #ClimateChange, according to new research out of The University of Texas at Austin.
As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the #atmosphere. The #CO2 released via groundwater could also contribute to ocean #acidification.
"The #Arctic coast is changing in front of our eyes," said Bayani Cardenas, a co-author of this study and professor at the Jackson School's Department of Earth and Planetary Sciences. "As #permafrost thaws, it turns into coastal and submarine #aquifers. Even without this thawing, our studies are among the first to directly show the existence of such aquifers."
