Nico Caltabiano, an oceanographer works for the World Meteorological Organization （WMO）， made waves in an entirely different field at the Paris Olympics this year—umpiring table tennis. Nico's transition from the depths of the ocean to the fast-paced world of table tennis officiating is as inspiring as it is unexpected.

During 2014 to 2017, Nico served at the International CLIVAR Project Office hosted by the First Institute of Oceanography （FIO） in Qingdao, China, which is also the leading institute of the OSF Programme. It was here that Nico developed a close connection with the FIO community not only in science but also in sports, as a regular of the institute's playground. Nico then joined the World Climate Research Programme and later the World Weather Research Programme, both under the WMO. His work in these roles has been instrumental in coordinating global research efforts on climate change—a cause he remains deeply committed to.

Yet, amidst his demanding scientific career, Nico nurtured a surprising passion: table tennis umpiring. What began as a simple act of keeping score at his son's tournaments gradually evolved into a serious pursuit. This year, his dedication culminated in a remarkable achievement—being selected as one of the officials at the Paris Olympics. Nico’s role as one of the two umpires in the Men’s Singles gold medal match highlighted his expertise and composure under pressure.
