An international research group led by Naveen Chandra of National Institute for Environmental Studies (NIES), Tsukuba, and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka performed the first quantitative study of CH4 growth rate in Earth’s atmosphere covering the past 3 decades. The research found out the emissions from oil and gas exploitation and natural climate events slowed down CH4 growth rate (1988-1998) and led to the temporary pause (1999-2006).
This achievement was published in Journal of the Meteorological Society of Japan online on December 4th, 2020.
