A new study indicates that the speed of glacier melt has "doubled over the past two decades" -- far faster than anticipated or previously measured.
Obtaining accurate measurements of glacier melt, or glacier mass loss, has been difficult, the authors said.
From 2000 to 2019, the rate of glacier melt accelerated from an estimated . 36 meters per year to . 69 meters per year, the authors wrote.
In turn, the authors believe that glacier melt has contributed to an estimated 21% of sea level rise since 2000 -- almost a quarter of an inch.
Although the authors did not study the cause of the glacier melting, they did indicate that the areas where glaciers shrunk experienced changes in long-term precipitation and temperature, which are consistent with climate change.
In calculating the glacier melt rates, the 11 authors wrote that they hope it contributes to more accurate projections for sea level rise and water management.
