Glaciers’ Self-Cooling Effect Fades as Climate Change Wins Battle

Glaciers’ Self-Cooling Effect Fades as Climate Change Wins Battle
—————————————–
New research from the Institute of Science and Technology Austria (ISTA) reveals that glaciers possess a temporary self-defense mechanism against rising global temperatures, but this natural ability is rapidly losing the battle against climate change.

According to an article published by SciTechDaily, glaciers have been observed to resist warming by cooling the air masses that come into contact with their icy surfaces. This process, which creates cold winds that flow down the slopes (katabatic winds), helps protect the glacier’s microclimate and slows the melting rate.

However, a study published in Nature Climate Change projects that this self-cooling ability is expected to reach its maximum effectiveness within the next decade (between the 2020s and 2040s). After this point, the mechanism will fail as the glaciers’ massive ice loss and fragmentation intensify due to human-caused warming.

The research indicates that once the cooling ability peaks, the glaciers will “recouple” to the steadily warming atmosphere. This reversal will lead to a more rapid rise in near-surface temperatures and a corresponding acceleration of melting and retreat toward the middle of the century, sealing their decline.

Scientists urge global policymakers to accept the committed ice loss and focus efforts on limiting further climatic warming rather than pursuing ineffective geo-engineering strategies, emphasizing that every fraction of a degree reduction in warming counts.
