...newly published report they note that the Yucatan rock around Chicxulub contains abundant amounts of sulfur. The blast must have vaporized the sulfur, they say, and spewed more than 100 billion tons of it into the atmosphere, where it mixed with moisture to form tiny drops of sulfuric acid. These drops created a barrier that could have reflected enough sunlight back into space to drop temperatures to near freezing, and could have remained airborne for decades. "It could have been up to a century," says Kevin Baines, an atmostpheric scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. "Most...
...China meets its energy needs has an impact far beyond its boundaries. Sulfurous emissions from Chinese power plants and factories blow eastward and fall as acid rain on Japan and Korea.
