Second round of frigid air visits U.S.

Second round of frigid air visits U.S.

Another band of arctic air began creeping into the northern United States on Monday, bringing a wave of frigid temperatures that could linger for most of the week across the upper Midwest and New England. Temperatures plunged below zero in North Dakota and northern Minnesota on Monday morning. The cold front was expected to sweep south into Iowa and as far east as Maine by tonight, and remain entrenched through Thursday. The bitter blast will lead to a swath of subzero temperatures, with highs in the single digits and wind chills of minus 20 or colder, said Paul Collar, a meteorologist with the National Weather Service. "It's not to the extent of the last outbreak but it's still bitterly cold," he said, referring to the recent polar vortex that sent temperatures plunging well below zero across much of the country and was blamed for at least a dozen deaths.

Study says China pollution reaches U.S.

Filthy emissions from China's export industries are carried across the Pacific Ocean and contribute to air pollution in the western United States, according to a paper published Monday by a prominent U.S. science journal. The research is the first to quantify how U.S. air pollution is affected by China's production of goods for export and by global consumer demand for those goods, the study's authors say. It was written by nine scholars based in three nations and was published by Proceedings of the National Academy of Sciences, which last year published a paper by other researchers that found a drop in life-spans in northern China because of air pollution. The latest paper says that "outsourcing production to China does not always relieve consumers in the United States … from the environmental impacts of air pollution."

Dinosaur hall to close for renovation

More than 65 million years after they went extinct, dinosaurs are about to disappear again — at least from public view in Washington. The Smithsonian's National Museum of Natural History said that its high-traffic dinosaur hall will close April 28 for a $48 million makeover. Most of the popular specimens won't reappear until 2019, when the Fossil Hall is reopened at the world's second-most-visited museum.
