Short summary
Energy consumption in Asia has substantially risen since 1970, leading to increased levels of air pollution, which can have severe impacts on human health and the environment. We present the first continuous ice-core record of toxic trace metals that covers 1971–2015. This new record from the Guliya ice cap in northwestern Tibet shows that Pb, Cd, Zn, and Ni, emitted mostly from fossil fuel combustion and biomass burning in South Asia, have reached the remote, high-altitude glacier since 1990.
