Glaciers on the Brink: 82,000 Gone by 2100 if Global Warming Hits 4°C

Researchers at ETH Zurich have estimated that if global temperatures rise to 4.0 C, only about 18,000 glaciers would remain worldwide by the end of this century. This drastic reduction is in stark contrast to the scenario where temperatures are limited to 1.5 C, which could preserve roughly 100,000 glaciers. The findings, published in a recent international study, mark a significant milestone in understanding the impact of climate change on glaciers globally. According to the study, the researchers introduced the concept of "Peak Glacier Extinction," which marks the year when glaciers are expected to reach their lowest point. This concept highlights the urgent need for immediate action to mitigate climate change and preserve the world's glaciers. "The study shows that every fraction of a degree of warming could decide the fate of glaciers," said Dr. Lander Van Tricht, Chair of Glaciology at ETH Zurich and lead author of the study. "It's a stark reminder of the importance of taking drastic measures to reduce greenhouse gas emissions and limit global warming." The study, which analyzed data from over 200,000 glaciers worldwide, found that the rate of glacier loss is accelerating at an alarming rate. In the Alps, for example, the number of glaciers has decreased by 50% since the 19th century. The researchers warn that the loss of glaciers will not only have significant environmental impacts but also affect local communities and economies that rely on glacier tourism and hydroelectric power. The study's findings have significant implications for policymakers and governments around the world. "The study highlights the urgent need for immediate action to reduce greenhouse gas emissions and limit global warming," said Dr. Van Tricht. "We need to take drastic measures to preserve the world's glaciers and mitigate the impacts of climate change." The researchers are now calling on governments and international organizations to take concrete steps to reduce emissions and protect glaciers. The study's findings have also sparked concern among environmental groups and local communities. "The loss of glaciers is a tragedy that will have far-reaching consequences for our planet," said a spokesperson for the environmental group, Greenpeace. "We urge governments to take immediate action to reduce emissions and protect glaciers." The researchers are now working with policymakers and international organizations to develop strategies to preserve the world's glaciers and mitigate the impacts of climate change. As the world continues to grapple with the impacts of climate change, the study's findings serve as a stark reminder of the urgent need for action. The researchers are now working to raise awareness about the importance of preserving glaciers and mitigating the impacts of climate change. "The study is a wake-up call for the world to take immediate action to protect our planet's glaciers," said Dr. Van Tricht. "We hope that our findings will inspire governments and international organizations to take concrete steps to reduce emissions and preserve the world's glaciers."
