NEW YORK, Nov. 28 (Xinhua) -- Balloons are regularly released from different places in the United States and some sites around the globe to make up a system that alerts American scientists to geoengineering, said The New York Times on Thursday.
Every few weeks, researchers in Boulder, Colorado, release a balloon that rises 17 miles into the sky. Similar balloons are launched with less frequency from sites in Alaska, Hawaii and New Zealand; Reunion Island, near the coast of Africa; and even Antarctica.
