In that region, more than 50 miles above Earth's surface, carbon emissions cause cooling rather than warming because carbon dioxide molecules collide with oxygen atoms and release heat into space. Because such cooling makes the planet's atmosphere contract, it can reduce drag on satellites and debris that orbit the earth, possibly having "adverse consequences for the orbital debris environment that is already unstable," the researchers wrote. http://www.latimes.com/news/science/sciencenow/la-sci-sn-climate-change-satellites-debris-20121112,0,3501663.story?track=rss
