Title: Radiocarbon Fingerprinting Black Carbon Source History in the Himalayas

Journal Article · · Geophysical Research Letters

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 (ƒbiomass) has grown from 24% ± 4% to 30% ± 4% since 1990. Intriguingly, we further find the ƒbiomass 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.
