NASA will hold a media teleconference at 11 a.m. PDT (2 p.m. EDT) Thursday, Oct. 12, to discuss new research to be published this week on changing global levels of carbon dioxide in the atmosphere. The research is based on data from NASA's Orbiting Carbon Observatory-2 (OCO-2) mission and other satellites.

NASA launched OCO-2 in 2014 to gather global measurements of atmospheric carbon dioxide with the resolution, precision and coverage needed to understand how this important greenhouse gas moves through the Earth system and how it changes over time.

The teleconference panelists will be:

  • Michael Freilich, director, Earth Science Division, NASA Headquarters, Washington
  • Annmarie Eldering, OCO-2 deputy project scientist, NASA's Jet Propulsion Laboratory, Pasadena, California
  • Junjie Liu, research scientist, JPL
  • Scott Denning, professor of atmospheric science, Colorado State University, Fort Collins

Visuals to accompany the telecon will be available shortly before it starts at:

The public may ask questions during the briefing on Twitter using the hashtag #askNASA.

Audio of the briefing, as well as supporting graphics, will stream live at:
