How horses can save the permafrost

Source: sciencedaily.com

Permafrost soils in the Arctic are thawing. As they do, large additional quantities of greenhouse gases could be released, accelerating climate change. In Russia, experiments are now being conducted in which herds of horses, bison and reindeer are being used to combat this effect. A study from Universität Hamburg, just released in the Nature journal Scientific Reports, now shows for the first time that this method could indeed significantly slow the loss of permafrost soils.

Theoretically speaking, 80 percent of all permafrost soils around the globe could be preserved until the year 2100, as has now been demonstrated by Prof. Christian Beer from Universität Hamburg’s Center for Earth System Research and Sustainability (CEN), an expert on the permanently frozen soils found throughout the Northern Hemisphere. If no action is taken to prevent it, half of the world’s permafrost will thaw by 2100. The new study explores a somewhat unconventional countermeasure: resettling massive herds of large herbivores.
