The Siberian tundra could almost completely disappear.?As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which home to a unique mix of flora and fauna. Experts from the Alfred Wegener Institute have now prepared a computer simulation of how these woods could spread in the future, at the tundra’s expense. Their conclusion: only consistent climate protection measures will allow roughly 30 per cent of the Siberian tundra to survive to mid-millennium. In all other, less favourable scenarios, the unique habitat is projected to disappear entirely. The study was just released in the journal eLife.

分析西伯利亞 1 月及 7 月的均溫,年降雨量和 3 項是否適合人類居住的指標,分別為生態景觀潛力（ecological landscape potential）,冬季嚴重指標（winter severity）及永凍土覆蓋率（permafrost coverage）,以進行模擬。團隊發現在未來西伯利亞的冬季均溫將升高 3.4~9.1°C，夏季均溫增加 1.9~5.7°C，降雨量則會增加 60~140 毫米（mm）。研究人員表示預計在 2080 年此地區氣候將變得溫和宜人,永凍土的覆蓋率將從當前的 65% 下降至 40%。

President Putin on Climate.

This political drama is being accompanied by evolving governmental positions on climate change. Putin’s public messaging has begun to pivot from promoting scientifically unproven theories, such as stating that "cosmic changes" are contributing to climate change and mocking the issue by expressing concern for worm populations near wind turbine installations. Putin has now noted how phenomena such as an unprecedented quantity of forest fires in Siberia are likely due to climate change and expressed a desire to collaborate with the US to confront increasing global temperatures. Officials speaking to the Japan Times indicated that the Russian COP26 delegation would be focusing on standards for calculating CO2 emissions and forest absorption, as well as exploring the idea of “rat[ing] nuclear power as green for carbon accounting purposes,” steps which are far from comprehensive solutions to the crisis. However, Putin’s decision not to attend brings into question his true commitment to aggressively confronting climate change.
