Arctic Siberia Summers 10 Degree Celsius Warmer in Last Interglacial, New Study Reveals
A new study reveals that Arctic Siberia experienced summer temperatures up to 10 degree Celsius warmer than today during the Last Interglacial period, which occurred approximately 115,000–130,000 years ago. Researchers analysed sediment cores and fossil records from the Dmitry Laptev Strait to reconstruct past environments. The study found signif...

Saber-Toothed Kitten Preserved for 37,000 Years Found in Siberian Ice
A saber-toothed kitten, frozen in Siberian permafrost for 37,000 years, has provided an unprecedented look at the extinct predator Homotherium latidens. Unearthed near the Arctic Circle, the well-preserved cub retains soft brown fur, intact whiskers, sharp claws, and footpads, offering unique insights into its anatomy. Radiocarbon dating revealed t...

Thawing Permafrost Releases Greenhouse Gases, Contributing to Global Warming
Recent studies reveal alarming changes in the Arctic's permafrost, which has been a significant carbon reservoir for millennia. As temperatures rise, thawing permafrost is releasing greenhouse gases, particularly methane. This shift is changing the region from a carbon sink to a net contributor to global warming. Research indicates that emissions f...

Earth's Northern Permafrost Region Has Climate Experts Worried. Here's Why
The study found that between 2000 and 2020, the region took up a fraction more carbon dioxide than it released.

'Zombie' Virus Which Spent 48,500 Years Frozen In Arctic Could Spark Deadly Pandemic, Warn Scientists
The scientists stated that the melting Arctic permafrost could release the 'zombie viruses' and trigger a catastrophic global health emergency

Frozen Time Bomb? Permafrost Thawing Below The Arctic Raises Alarm
The researchers stressed that the occurrence of gas accumulations was more widespread than anticipated.

Arctic Micro-Animal Survives 24,000 Years In Siberian Permafrost
A microscopic animal called a bdelloid rotifer came back to life after being frozen for 24,000 years in Siberia and then successfully made clones of itself, Russian scientists said Monday.

Arctic May Have Crossed Key Threshold, Emitting Several Tons Of Carbon
The Arctic is undergoing a profound, rapid and unmitigated shift into a new climate state, one that is greener, features far less ice, and is a net source of greenhouse gas emissions from melting permafrost, according to a major new federal assessment of the region released Tuesday.

Ancient Life Awakens Amid Thawing Ice Caps And Permafrost
From about 1550 to 1850, a global cold snap called the Little Ice Age supersized glaciers throughout the Arctic. On Canada's Ellesmere Island, Teardrop Glacier extended its frozen tongue across the landscape and swallowed a small tuft of moss.

Scientists Amazed As Canadian Permafrost Thaws 70 Years Early
Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

32,000-Year-Old Adult Wolf's Head Found In Russian Arctic
A first intact head of a gigantic adult wolf which died about 32,000 years ago and was preserved in permafrost has been found in the Russian Arctic, scientists have said.

The Arctic Is Full Of Toxic Mercury, And Climate Change Is Going To Release It
We already knew that thawing Arctic permafrost would release powerful greenhouse gases. On Monday, scientists revealed it could also release massive amounts of mercury - a potent neurotoxin and serious threat to human health.

Norway's 'Doomsday' Seed Vault Entrance Repaired After Global Warming Thaws Arctic Ice
The 'Doomsday' seed vault in Svalbard archipelago near the North Pole seeks to safeguard seeds by keeping them safe in natural permafrost from cataclysms such as nuclear war or disease.

The Arctic Is Being Utterly Transformed - And We're Just Starting To Learn The Consequences
It's the fastest-warming part of the planet -- and the impacts will be felt far, far afield. Among many other assorted impacts, the rapidly melting Arctic is expected to flood shorelines as Greenland loses ice more and more rapidly (it contains some 20 feet of potential sea level rise), further pump greenhouse gases into the atmosphere as permafros...
