Abstract:
We employ a high-resolution Köppen climate classification dataset to examine
shifts in Tundra zones within the Alps and Asia. Our analysis shows substan-
tial reductions in Tundra areas by the mid-21st century under different Shared.
Socioeconomic pathways (SSP1-2.6, SSP3-7.0, SSP5-8.5). Tundra zones in the
Alps and the Tibetan Plateau are crucial for their unique climates and role as
water reservoirs. Characterized by short, mild summers and long, severe win-
ters, these zones are vital for the glaciers and perennial snow. The projected
climate instability may significantly reduce alpine snow cover by mid-century
with irreversible consequences. A 2C temperature increase from the 1981–
2010 baseline could eliminate the Tundra climate in the Alps and reduce it by
over 70% in Asia. This is particularly concerning given that rivers from the
Tibetan Plateau sustain nearly 40% of the global population.
