| 英文摘要 | Black carbon (BC) is considered as an important contributor to the Himalayan glaciers melt in the past few decades. However, the long-term source apportionment of BC remains unclear. Here we present the first radiocarbon (14C)-based annual variation of BC source apportionment in an ice core spanning the period of 1959-2012 drilled from the Southeastern Tibetan Plateau, a receptor site of South Asia outflow. We find fossil fuel combustion is a major contribution (73% +/- 5%), yet the biomass burning fraction (& fnof;biomass) has grown from 24% +/- 4% to 30% +/- 4% since 1990. Intriguingly, we further find the & fnof;biomass demonstrating a robust correlation with South Asian wildfires linked to climate oscillations. Thus, for mitigating BC impacts on Himalayan glaciers, South Asia's transition from fossil fuels to clean energy is a more efficient and urgent strategy than reducing residential biomass burning. |
