Ofa Fa'anunu was speaking during a meeting of the Pacific Meteorological Council held in Apia earlier this month.
The Samoa meeting brought together directors from the international development agency - the National Meteorological and Hydrological Services (NMHS), donor and funding agencies as well as the private sector to strengthen climate and weather services in the Pacific.
Mr Fa'anunu, who is also the Director of Tonga's Meteorology office, said the Pacific was at the forefront of the world's changing climate.
