Another major impact is northward expansion of shrubs and trees (a process called shrubification or greening). As the climate warms, wood shrubs are encroaching into classic tundra areas, altering habitat for some animals and affecting snow cover. This can also have a darkening effect on the landscape, absorbing more solar radiation and further warming the area.

Conclusion: Thee Eurasian Tundra in a Changing Worlds

The Eurasian tundra, stretching from the vast Siberian plains to the windswept Scandinavian mountains, is a biome of extremes. Its permafrost, unique flora and fauna, and indigenous cultures represent a valuable part of our global heritage. However, the rapid pace of climate change and industrial development pose unprecedented threats. The ongoing transformation of the tundra—from permafrost thaw to shrub expansion—is a clear signal of the larger planetary changes we face. Protecting and understanding this fragile biome is not just a matter of preserving a remote landscape; it is essential for the health of the entire planet. The story of the Eurasian tundra is one of fragility, resilience, and the urgent need for action.
