Siberia has warmed up faster than almost anywhere else on Earth. Scientists say the planet's warming must not exceed 1.5 degrees Celsius — but Siberia's temperatures have already spiked far beyond that.

the region near the town of Zyryanka, in an enormous wedge of eastern Siberia called Yakutia, has warmed by more than 3 degrees Celsius since preindustrial times — roughly triple the global average.

The permafrost that once sustained farming — and upon which villages and cities are built — is in the midst of a great thaw, blanketing the region with swamps, lakes and odd bubbles of earth that render the land virtually useless.

Students in Siberia have opened a 50-year-old time capsule containing a wish for peace and international friendship from their Soviet peers, local media reported Thursday.

The Soviet students’ message of hope for a peaceful future was unearthed as Russia faces unprecedented economic and political isolation in the wake of its invasion of Ukraine. 

In a letter placed inside the time capsule, the Soviet middle schoolers recite the history of the Young Pioneers and boast of the engineering achievements of the U.S.S.R. before wishing their descendants peace and international cooperation.

“The colonization of the Americas involved multiple technologically divergent, and possibly genetically divergent, founding groups.”

Indeed, new genetic evidence described in the current issue of the journal Nature shows that the Americas appeared to be first populated by three waves of migrants from Siberia: one large migration about 15,000 years ago, followed by two lesser migrations. Such a pattern had been hypothesized 25 years ago on the basis of Native American language groups spoken today, but had not been widely accepted by linguistics scholars.

human DNA from the cave, extracted from coprolites, or dried feces, pointed to Siberian-East Asian origins of the people.

Dr. Clapham and his co-author, Jonathan L. Payne, a Stanford geochemist, concluded that animals with skeletons or shells made of calcium carbonate, or limestone, were more likely to die than those with skeletons of other substances. And animals that had few ways of protecting their internal chemistry were more apt to disappear. Being widely dispersed across the planet was little protection against extinction, and neither was being numerous. The deaths happened throughout the ocean. Nor was there any correlation between extinction and how a creature moved or what it ate. Instead, the authors concluded, the animals died from a lack of dissolved oxygen in the water, an excess of carbon dioxide, a reduced ability to make shells from calcium carbonate, altered ocean acidity and higher water temperatures. They also concluded that all these stresses happened rapidly and that each one amplified the effects of the others. That led to a wholesale change in the ocean’s dominant animals within just 200,000 years, or perhaps much less, Dr. Clapham said.

So what happened 252 million years ago to cause those physiological stresses in marine animals? Additional clues from carbon, calcium and nitrogen isotopes of the period, as well as from organic geochemistry, suggest a “perturbation of the global carbon cycle,” the scientists’ second paper concluded — a huge infusion of carbon into the atmosphere and the ocean.

scientists suspect that the answer lies in the biggest volcanic event of the past 500 million years — the eruptions that formed the Siberian Traps, the stairlike hilly region in northern Russia. The eruptions sent catastrophic amounts of carbon gas into the atmosphere and, ultimately, the oceans; that led to long-term ocean acidification, ocean warming and vast areas of oxygen-poor ocean water

today’s Europeans descend from three groups who moved into Europe at different stages of history.

The first were hunter-gatherers who arrived some 45,000 years ago in Europe. Then came farmers who arrived from the Near East about 8,000 years ago.

Finally, a group of nomadic sheepherders from western Russia called the Yamnaya arrived about 4,500 years ago. The authors of the new studies also suggest that the Yamnaya language may have given rise to many of the languages spoken in Europe today.

Ancient squirrel's nest leads to discovery of giant virus

The virus has been at rest for 30,000 years about 30 meters deep in the Siberian permafrost. Astrobiologists using it as kind of stand-in for Mars have taken core samples looking for life. Claverie said he stumbled on research that described reviving a plant from a seed that had been buried for 30,000 years.

The amount of CO2 in the atmosphere reached record levels in 2020, hitting 417 parts per million in May. The last time CO2 levels exceeded 400 parts per million was around four million years ago, during the Pliocene era, when global temperatures were 2-4C warmer and sea levels were 10-25 metres (33-82 feet) higher than they are now.

The past decade was the hottest on record. The year 2020 was more than 1.2C hotter than the average year in the 19th Century. In Europe it was the hottest year ever, while globally 2020 tied with 2016 as the warmest. Record temperatures, including 2016, usually coincide with an El Niño event (a large band of warm water that forms in the Pacific Ocean every few years), which results in large-scale warming of ocean surface temperatures. But 2020 was unusual because the world experienced a La Niña event (the reverse of El Niño, with a cooler band of water forming). In other words, without La Niña bringing global temperatures down, 2020 would have been even hotter.

Nowhere is that increase in heat more keenly felt than in the Arctic. In June 2020, the temperature reached 38C in eastern Siberia, the hottest ever recorded within the Arctic Circle. The heatwave accelerated the melting of sea ice in the East Siberian and Laptev seas and delayed the usual Arctic freeze by almost two months

Rune Rafaelsen has a bold plan that could raise the profile of his remote Arctic town — with a little help, he hopes, from China.

He is the mayor of Sor-Varanger, a municipality in the far northeast corner of Norway, close to the Russian border. His office is in the small town Kirkenes — population a little over 3,500 — which overlooks the icy gray Barents Sea.

"Now you can go from Asia to Europe through the Northern Sea Route.

A renewed buildup of Russian troops near the Ukrainian border has raised concern among some officials in the United States and Europe who are tracking what they consider irregular movements of equipment and personnel on Russia’s western flank.

The renewed movements of Russian forces in the area come as the Kremlin embraces a harder line on Ukraine. Russian officials from President Vladimir Putin on down have escalated their rhetoric in recent months, attacking Kyiv’s Western ties and even questioning its sovereignty.

The situation also comes as the simmering 7½-year conflict between Ukrainian forces and Russian-backed separatists in the eastern Donbas region enters a new stage. On Oct. 26, Ukraine’s military confirmed it had used a Turkish-made drone against a position in Donbas, the first time Kyiv has employed the technology in combat, prompting an outcry from Moscow.
