Eine neue Studie bestätigt, dass die Hauptursache des immer schnelleren Anstiegs des Methan-Gehalts der Atmosphäre die Aktivität von Mikroaorganismen ist, die durch die globale Erhitzung zunimmt. Damit handelt es sich um einen Feedback-Mechanismus, durch den sich die globale Erhitzung selbst verstärkt. https://taz.de/Zu-viel-Methan-in-der-Atmosphaere/!6045201/

Sibirien macht gerade die schlimmste Hitzewelle der aufgezeichneten Geschichte durch. Im Juni wurden Temperaturen von über 40 Grad erreicht. damit droht sich das Abschmelzen des Permafrosts – durch die Freisetzung von Methan ein sich selbst verstärkender Prozess – zu beschleunigen. https://www.liberation.fr/environnement/climat/siberie-avec-40-c-la-region-connait-la-pire-vague-de-chaleur-de-son-histoire-20230611_QONTZ25VFRASJMR6UT44HXDO7A/

Tartary was a vast, cold country in the northern parts of Asia, bounded by Siberia on the north and west. A vast tract of land in northern and central Asia, it stretched from the Caspian Sea and the Ural Mountains to the west, all the way to the Pacific Ocean in the east. It was inhabited mostly by Mongol peoples.

This proportion would not change for the next 200 years, despite the large increase in populations in Siberia. In 1897, the huge eastern territory had a population of 909,000 Russian inhabitants, while the west had three times more.

The Medvezhye Pipeline is a pipeline built on the Medvezhye oil and gas field (Shabad). This naturally occurring gas field is located in Northern Siberia. Officials hoped the institution of the pipeline would provide industrial Russian communities with oil by the late 1970s. Siberia also signed contracts with Italy, France, and West Germany and agreed to provide natural gas in exchange for pipes. The pipeline was built in a sub-Arctic region with harsh weather and frozen ground and many worried that the pipeline would not be constructed according to schedule. The Medvezhye pipeline was constructed on warming, unstable permafrost. The pipeline was commissioned in 1972 and is Russia’s third most highly producing pipeline (Seligman). In 1977, a study was performed to measure pipe deformation due to warming permafrost conditions. No deformation was found due to the pipe’s thickness. As of 2011, the pipeline’s managers, Victoria Oil and Gas PLC, reported that the pipeline had 400 million barrels of oil in place (Victoria Oil and Gas). In continued monitoring and development of the pipeline, Victoria Oil and Gas also performed studies to determine possible new drilling and well sites, production infrastructure, and downstream hydrocarbon emissions effects. Victoria Oil and Gas also studied oil export from the pipeline to Siberia and other parts of Russia. Today, the pipeline is still a major source of oil and gas for Russia. A map of the Medvezhye oil and gas field can be found below. http://images.energy365dino.co.uk/standard/126082_7a87a50d3cd24d7da925.jpg
