Research Abstract

We have reconstructed past climatic and environmental changes using an ice core drilled on King Col, Mt. Logan, Yukon, Canada. Climate of this site is strongly influenced by Pacific Decadal Oscillation. Sulfate and nitrate increased significantly since 1940s due to anthropogenic input of the atmospheric pollutants. This is in contrast with a higher elevation site on the same mountain, which does not show the anthropogenic increases of these species. This result confirms altitudinal dependence of environmental changes.
