A CAT scan for the Earth: CU, NOAA scientists are looping around the globe in a NASA airliner to measure greenhouse pollutants

Scientists treating Earth as a feverish patient are giving it the equivalent of a CAT scan, targeting short-life pollutants that spur climate change to try to find a remedy that dials back the heat.

The NASA DC-8, flying airborne chemistry lab, does a test flight over the Rocky Mountain Metro Airport runway on Sept. 26, 2017 in Broomfield. Climate researchers in the DC-8 plane will soon fly from the North Pole to the South collecting data that will make global climate modeling more accurate. NOAA, NASA and Harvard have partnered in the mission. (Credit: RJ Sangosti, The Denver Post)
