Группа выше: Изменение климата и углерод
Смысл: The main idea is that thawing Arctic permafrost poses a severe threat to the global climate due to the release of ancient carbon, and the restoration of Pleistocene-era grasslands through the introduction of megafauna is a viable scientific strategy to stabilize this carbon and prevent a climate catastrophe.
Pleistocene Park in Siberia attempts to combat global warming by restoring ancient mammoth-steppe ecosystems to prevent the release of massive carbon deposits from thawing permafrost.
Смысл: The main idea is that the thawing of Arctic permafrost creates a dangerous positive feedback loop where the release of massive amounts of ancient stored carbon and methane will accelerate global warming far beyond the impact of human industrial emissions.
Thawing Siberian permafrost threatens to release 1,670 billion tons of carbon, potentially raising global temperatures by 10 degrees Celsius and destroying regional infrastructure.
