High Levels of Molecular Chlorine in Atmosphere Above Arctic Noted

Scientists, led by Greg Huey a professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, recently studied the atmosphere above Barrow, Alaska, which is located within the Arctic Circle, and have discovered extraordinary levels of molecular chlorine in the air.  Scientists are concerned that high levels of the highly reactive chemical will have a very strong influence on the atmospheric chemistry above the Arctic.

Meanwhile, the European Union's executive arm has unveiled what it calls an ambitious new climate change and energy policy. A new study reveals that the smog that frequently chokes China comes partially from factories that supply the rest of the world with various goods.  Some of that pollution also winds up being exported to other countries. Someday, implanted medical devices such as a heart pacemaker may be powered by the movement of the body's organs. Officials from China's space agency joined their peers from 30 other countries in a recent meeting held here in Washington, DC.  Some think China’s presence at the meeting may signal their possible cooperation with international space exploration efforts.
