The world could lose as much as 41% of its total glacier mass this century, or as little as 26%, depending on today’s climate change mitigation efforts. With continued investment in fossil fuels, over 40% of the glacial mass will be gone within the century, and over 80% of glaciers could well disappear. Even in a best-case, low-emissions scenario, with increase in global mean temperature limited to +1.5° C relative to pre-industrial levels, over 25% of glacial mass will be gone and nearly 50% of glaciers are projected to disappear. A majority are small (less than one km2) by glacial standards, but their loss can negatively impact local hydrology, tourism, glacier hazards, and cultural values. Moreover, glacier melt across the world has accelerated over the past two decades with resulting meltwater accounting for 21% of global sea level rise over the same period.
