A recent study finds that nearly 40% of the world's glaciers are doomed to melt due to fossil fuel emissions, a figure that could reach 75% if global temperatures increase by 2.7C. Such extensive glacier loss would drastically raise sea levels, threatening millions and triggering mass migrations. The research emphasizes the importance of limiting emissions to the 1.5C target to save half of the glacier ice. Each increase in temperature affects ice reserves, highlighting the urgency of climate action and its long-term impact on ecosystems and water security.
Almost 40% of glaciers in existence today are already doomed to melt due to climate-heating emissions from fossil fuels, with a potential 75% loss at 2.7C rise.
The massive loss of glaciers would push up sea levels, endangering millions and driving mass migration, profoundly affecting billions reliant on glaciers for water.
Every tenth-of-a-degree rise avoided could save 2.7 trillion tonnes of ice, making clear that every fraction of a degree matters.
Our study makes it painfully clear that every choice we make today will resonate for centuries, determining how much of our glaciers can be preserved.
