Researchers found the world's largest reserve of natural mercury hidden underneath Arctic permafrost. The discovery, however, comes with the warning that the toxic element may be released if the permafrost thaws due to climate change.

No seeds were compromised when the Svalbard Global Seed Vault became flooded by permafrost melt recently. But Norwegian government officials are not taking any chances and are upgrading the "doomsday" vault facility amid climate change.

The world’s backup seed vault experienced water intrusion due to melted permafrost. The Norwegian government is now placing extra precautions to ensure the safety of the vault’s contents.

The Batagaika Crater, also known as the 'doorway to hell,' is the result of melting permafrost in Siberia. The crater offers climate scientists an opportunity to view more than 200,000 years of climate change in the region.

Melting permafrost in the Arctic produces carbon dioxide and methane that may further exacerbate warming climate. What conditions influence the release of these greenhouse gases?
Earth/Environment June 14, 2016
Two new studies warned that organic carbon from thawing permafrost was being quickly converted into more carbon dioxide into the air and water. Increased CO2 levels in the atmosphere had led to further warming of the planet and had triggered more thawing of permafrost.

Scientists are worried that if temperature levels of permafrost in Alaska continually rise up, thawing of these frozen soils will begin by 2070. Melted permafrost will trigger the acceleration of global warming.

Scientists discovered a giant prehistoric virus frozen in Siberian permafrost. This is the second prehistoric virus discovered by the same team and the fourth overall since 2003. Resembling human pathogens, the virus could pose a threat to humans and animals if unleashed. The researchers are still assessing whether it could be infectious or not.

Research ecologists warn that the continued occurrence of wildfires in Alaska could potentially lead to more carbon emissions in the air, especially when the carbon deposits in the permafrost are to be released.

The amount of shrub in the Arctic increases with the rise in global temperatures, a phenomenon that causes the thawing of the permafrost and worsens global warming.

As nations gather for climate talks, researchers warn of a vicious global warming cycle that could be triggered by the thawing of permafrost. Northern Hemisphere permafrost holds twice the carbon already in the atmosphere, they say.

Thawing permafrost in the Arctic is likely to take decades, not years, to release vast quantities of greenhouse gases into the atmosphere. Why is this still not good news for the environment?
Earth/Environment April 8, 2015
Permafrost layer keeping methane from leaking into the atmosphere from ocean off Siberia is thin and weak, researchers say. Thawing with global warming could release a flood of the greenhouse gas into the atmosphere, they say.

Mysterious large holes are appearing in remote parts of Siberia. Environmental scientists believe they indicate a new and alarming trend linked to global warming.
