Siberia: Why mysterious craters exploded in the Russian Arctic permafrost, according to scientists

CNN

CNN — A decade ago, a mysterious crater appeared in the Russian Arctic, forming a huge jagged hole hundreds of feet wide, plunging down into an inky abyss. It goes Sandwiched between the two are unusual pockets, about 3-feet thick, of salty, unfrozen water called “cryopegs.” As climate change drives warmer temperatures, the top layer of soil is melting, causing …

Glaciologist digs deep into permafrost to gauge future disasters

The Hindu

Possible collapse of permafrost, which are permanently frozen rock or soil formations, is an emerging climate-change induced issue in the upper reaches of the Himalayas. Remya from Kerala, who is part of this year’s India’s Arctic Expedition, currently based at the Himadri research station in Norway, says that her work is aimed at identifying the probability of disasters due to …

Arctic ocean may absorb less CO2 than projected due to coastal erosion

LA Times

As Earth warms, the Arctic Ocean’s ability to absorb carbon dioxide from the atmosphere is waning due to melting permafrost and worsening coastal erosion, according to new research. “For the first time, we can actually put a sign — maybe not a number but a sign — on the change in the Arctic Ocean’s ability to take up CO2 from …

Rivers in Alaska are turning orange. It’s an ‘unexpected consequence of climate change’

CNN

CNN — Rivers and streams in Alaska are changing color – from a clean, clear blue to a rusty orange – because of the toxic metals released by thawing permafrost, according to a new study. “But it’s very startling to see it when you’re on some of the most remote wilderness and you’re far from a mine source.” An aerial …

研究：气候变化导致阿拉斯加河流变为橙色

China Daily

几年前，人们惊讶地发现，美国阿拉斯加数十条河流里的水变成了“橙汁”。研究指出，事实上，这是被铁锈污染的河流，而铁锈则来自因全球变暖而融化的冻土。卫报截图 Dozens of rivers and streams in Alaska are turning rusty orange, a likely consequence of thawing permafrost, a new study finds. 研究作者、加州大学戴维斯分校环境毒理学助理教授布雷特·普林说：“这是美国最原始的一些河流中看到的气候变化的不可预见影响。” The permafrost thaw is exposing minerals to oxygen in a process known as weathering, which increases the acidity of the water and dissolves metals like zinc, copper, cadmium and iron – the most apparent metal that …

'Zombie Viruses' trapped in Siberia may trigger a new pandemic, warns study

India TV News

According to a study, a new pandemic could be sparked by the emergence of ancient zombie viruses that have been trapped in Siberian permafrost due to global warming and increased human activity such as shipping and mining. The viruses, which have been known for years as 'Methuselah microbes', are capable of reproducing and causing disease even if they have lain …

What is the effecting of thawing permafrost on seafloor?

The Hindu

A new study from Monterey Bay Aquarium Research Institute researchers and their collaborators have document how the thawing of permafrost, submerged underwater at the edge of the Arctic Ocean, is affecting the seafloor. Numerous peer-reviewed studies show that thawing permafrost creates unstable land which negatively impacts important Arctic infrastructure, such as roads, train tracks, buildings, and airports. Using advanced underwater …

Holes the size of city blocks are forming in the Arctic seafloor

CNN

Sign up for CNN’s Wonder Theory science newsletter. CNN — Marine scientists have discovered deep sinkholes – one larger than a city block of six-story buildings – and ice-filled hills that have formed “extraordinarily” rapidly on a remote part of the Arctic seafloor. Mapping of Canada’s Beaufort Sea, using a remotely operated underwater vehicle and ship-mounted sonar, revealed the dramatic …

Emissions Due to Arctic Fires, Thawing Permafrost Pose Growing Threat to Climate, Finds Study

News 18

The warming Arctic tundra will make it harder for the world to curb climate change, as thawing permafrost and wildfires release greenhouse gases that are not fully accounted for in global emissions agreements, a study said on Monday. “The Arctic is in the process of disintegrating as we know it, and the permafrost is one major component with some pretty …

Lightning strikes could spark more Arctic wildfires, says study

Live Mint

Lightning strikes inside the Arctic circle may double this century, sparking widespread tundra fires and increasing the risk of setting off the carbon time bomb held within permafrost, new research showed Monday. "We projected how lightning in high-latitude boreal forests and Arctic tundra regions will change across North America and Eurasia," said Yang Chen, a researcher at the University of …
