Arctic Sea Ice 2021 : Environment, Weather & Climate - Peak Oil News and Message Boards

Another 2030 point, goal on the agenda. Great reset at work.
Despite the fact that the area of the Arctic Ocean covered by sea ice during the winter maximum has declined only slightly in recent decades, the ice itself is profoundly different than it used to be. Very old ice thick, strong, and more melt-resistant has nearly vanished, and the amount of first-year ice thin, salty, and unlikely to survive the summer has skyrocketed.
This time series shows the Arctic sea ice extent in millions of square kilometers over the past roughly 1,500 years. Scientists use climate proxies like sediment/ice cores, tree rings, and fossilized shells of ocean creatures to extend the sea ice extent records back in time. These records show that while there have been several periods over the past 1,450 years when sea ice extents expanded and contracted, the decrease during the modern era is unrivaled. And just as importantly, it is beyond the range of natural variability, implying a human compo ....

Oldest DNA of an Animal Not Preserved in Permafrost Extracted From a Cave Bear

Just days ago, I wrote an article about how the world’s oldest DNA was recovered from mammoths that lived more than a million years ago. The DNA was collected from three ancient mammoths that were preserved in the Siberian permafrost.
And now, new research has revealed that the oldest DNA from an animal not preserved in permafrost has been extracted from an ancient cave bear. The DNA was extracted from a large and vegetarian 360,000-year-old cave bear that lived in what is now Georgia during the Middle Pleistocene Period.
The cave bears’ scientific name is
Ursus kudarensis praekudarensis and they were known to hibernate in caves during the winter months. They weighed as much as a tonne (over double the size of a male polar bear) despite only eating plants and since they had a hard time storing fat away for their hibernation periods, they occasionally died during the winter months. ....

Prehistoric Animal Viruses From the Permafrost Caught Interest of Russian Scientists

Close
Scientists are examining prehistoric viruses from the Siberian permafrost in the animal dug. A lab in Russia s Siberia state is beginning study about prehistoric viruses conserved in the remnants of animals discovered in melting permafrost.
Led by the Biotechnology, University of Yakutsk and Vector State Research Centre of Virology, the research will begin by examining tissues from a prehistoric horse from at most 4,500 years ago.
These remnants were found in Yakutia, an area of Siberia, where Paleolithic animals such as mammoths are frequently seen.

Other Prehistoric Animals
The scientists strive to research other prehistoric animals including rodents, partridges, hares, elk, dogs, the 28,800-year-old Malolyakhovsky woolly mammoth, and more. Several of the remnants are above 50,000 years old. All the animals were discovered because of the thawing. ....
