Global glacier mass loss is projected to increase alongside rising temperatures

In short: A modelling study of global glaciers found that mass loss is linearly related to temperature increases. Researchers projected that glaciers could lose between 26% and 41% of their mass by 2100, depending on the level of global warming, potentially causing nearly half of all glaciers to disappear.

The study used projections for various socioeconomic pathways to estimate how glaciers, excluding ice sheets, will respond to different temperature scenarios. This research is significant because glacier retreat impacts sea level rise and water resources. However, the findings are based on climate models rather than direct physical observations of future changes.

The researchers found that a +1.5°C increase corresponds to a 26 ± 6% mass loss, while a +4°C increase corresponds to a 41 ± 11% loss.

Why it matters: The scale of glacier retreat and its impact on sea levels is directly tied to the degree of global warming.
