英文摘要 | Large volcanic eruptions impact climate through the injection of ash and sulfur-containing gases into the atmosphere. While the ash particles fall out rapidly, the gases are converted to sulfate aerosols that reflect solar radiation in the stratosphere and cause a lowering of the global mean surface temperature. Earlier studies have suggested that major volcanic eruptions resulted in positive mass balances and advances of glaciers. Here we perform a multivariate analysis to decompose global glacier mass changes from 1961 to 2005 into components associated with anthropogenic influences, volcanic and solar activities, and the El Niño-Southern Oscillation. We find that the global glacier mass loss was mainly driven by the anthropogenic forcing, interrupted by a few years of intermittent mass gains following large volcanic eruptions. The relative impact of volcanic eruptions has dwindled due to strongly increasing greenhouse gas concentrations since the mid-20th century. |
