Arctic air pollution: origins and impacts.

Local Arctic air pollution: Sources and impacts

Local emissions of Arctic air pollutants and their impacts on climate, ecosystems and health are poorly understood. Future increases due to Arctic warming or economic drivers may put additional pressures on the fragile Arctic environment already affected by mid-latitude air pollution. Aircraft data were collected, for the first time, downwind of shipping and petroleum extraction facilities in t...

Impacts of climate change on air pollution levels in the Northern Hemisphere with special focus on Europe and the Arctic

Ecological Monitoring of Acid Deposition in the Arctic Region

The issue of atmospheric air pollution in the Arctic is of global nature and concerns the entire humanity. The fragile nature of high latitudes is extremely vulnerable to human impacts. The negative effects are caused not only by plants and factories located in the northern latitudes but also by far away plants in Central Europe, America, and Asia. As a result, pollutants migrating to the Arcti...

Climate change and environmental impacts on maternal and newborn health with focus on Arctic populations

BACKGROUND In 2007, the Intergovernmental Panel on Climate Change (IPCC) presented a report on global warming and the impact of human activities on global warming. Later the Lancet commission identified six ways human health could be affected. Among these were not environmental factors which are also believed to be important for human health. In this paper we therefore focus on environmental fa...

The North Atlantic Oscillation controls air pollution transport to the Arctic

This paper studies the interannual variability of pollution pathways from northern hemisphere (NH) continents into the Arctic. Using a 15-year model simulation of the dispersion of passive tracers representative of anthropogenic emissions from NH continents, we show that the North Atlantic Oscillation (NAO) exerts a strong control on the pollution transport into the Arctic, particularly in wint...
