Meanwhile, the new study suggests the effect will intensify in the future with continued climate change, based on computer models that attempt to project how rising temperatures would affect the Arctic's chemical reservoirs.
That echoes a report released in February by the U.N. Environment Programme and the Arctic Monitoring and Assessment Programme. "For some POPs, climate change-induced enhancement of emissions may reduce the expected effectiveness of the Stockholm Convention" -- the international treaty that bans use of several POPs -- "resulting in releases decreasing less rapidly than targeted."
That's a concern of Hung's, as well.
"The main purpose of this paper is to raise the awareness that climate change actually has an influence on contamination," she said. "It's not as apparent as other, more visible changes. ... People need to be aware there is an effect. As we evaluate the effectiveness of the Stockholm Convention, we need to take into account the effects of climate change."
