Researchers last week claimed that sulfur emissions from cargo ships are causing ocean and coastal pollution and affecting scientific understanding of global climate change. Scientists at Carnegie Mellon University in Pennsylvania and Duke University in North Carolina said in a letter to the science journal Nature that ships are spewing more sulfur from their funnels than previously suspected which could be an important factor in solving the puzzle of global warming. "You've got to consider ships explicitly if you are going to understand ocean chemistry which is a foundation for understanding atmospheric chemistry and climate change," said James Corbett, an engineer at Carnegie Mellon. In some coastal regions ships also have a significant impact on air quality, he added.
