According to a study, the Siberian Tundra might almost reappear due to rising global temperatures ...

Global warming is posing a potentially disastrous threat to the Siberian tundra, the frozen lands near the Arctic Circle, according to scientists. They used a computer simulation to build on the tundra''s special ecosystem of dwarf shrubs, sedges, grasses, mosses, and lichens. The tundra would virtually disappear by mid-millennium if temperatures continued to grow rapidly. However, only 30 percent of today''s tundra would be saved, according to experts. This is

The tundra soil is rich in nitrogen and phosphorus and has large amounts of biomass stored as methane in the frozen ground, which is creating a carbon sink for the planet. However, global warming is causing a rapid increase in temperatures in the Arctic. As a result, the treeline for Siberian larch forests is steadily advancing towards the north, invading the tundra biodiversity. And a huge carbon sink for the planet will also disappear with it.

Only consistent climate protection measures will allow roughly 30 percent of the Siberian tundra to survive to the mid-millennium, according to researchers. In all other, less beneficial scenarios, the unique habitat is likely to disappear entirely. In the journal eLife, they released their findings.

The current and future warming will have serious implications, according to Prof Ulrike Herzschuh, the author of the study. In the worst-case scenario, there will be virtually no tundra left by the middle of the millennium.

Prof Herzschuh and AWI modeller Dr Stefan Kruse used the AWI vegetation model LAVESI, which Dr Krusay said would very realistically depict the growing treeline in a warming climate.

The larch forests might spread northward at an angle of up to 30 kilometers per decade, while the tundra habitat, which cannot be transformed into colder areas due to the adjacent Arctic Ocean, would increase. In the majority of scenarios, researchers discovered that only 6 percent of today''s tundra would remain by mid-millennium. If we implement aggressive measures to reduce greenhouse gases, roughly 30 percent could be saved.
