Our department is happy to share another achievement of prof. Parisa Ariya's scientific group. Their study about the development of sustainable and recyclable technology for removal of toxic metals such as mercury, instantaneously, has been published in the Scientific Reports section of the international journal of science, Nature Publishing. This technique uses metals which are found in airborne particles and on soil, and it does not use energy, and recycle and remove all materials.

Much of the influence on climate from air pollution in East Asia is driven by consumption in the developed countries of Western Europe and North America, according to research co-led by McGill University atmospheric scientist Yi Huang.

In a paper published online this week in Nature Geoscience, Huang and colleagues from China, the U.S. and U.K. report that international trade shifts the climate impacts of aerosols -- solid or liquid particles suspended in air -- from net consuming countries to net producing countries.

Study reveals how wind patterns change along with sea-surface temperatures

Shifting winds may explain why long-term fluctuations in North Atlantic sea surface temperatures have no apparent influence on Europe’s wintertime temperatures. The findings, published in Nature Communications, could also have implications for how Europe’s climate will evolve amid global warming.
