In an article in journal Science, it was reported that planetary science professor Yuk Yung, along with physics research scientist Tracey Tromp, Assistant Professor of Geochemistry John Eiler, planetary science research scientist Run-Lie Shia, and Jet Propulsion Laboratory scientist Mark Allen, were concerned that leaked hydrogen gas for use in hydrogen cars, in a hydrogen economy, could indirectly cause as much as a 10-percent decrease in atmospheric ozone.
His climate and space research relates to the work of Professor Kenneth J. Hsu (Swiss Federal Institute of Technology), Dr. Charles A Perry (United States Geological Survey) and Henrik Svensmark (Danish Meteorological Institute), in particular in the field of carbon-fluxing.
