A webinar entitled “Sea Level Rise: Is it Climate Change or Land Subsidence?” was conducted as part of NAMRIA’s celebration of the National Climate Change Consciousness (NCCC) Week. The webinar, aimed at raising consciousness on addressing the impacts of climate change, was streamed on 23 November 2022 via Zoom and YouTube Live.
The webinar consisted of two topics, both discussed by resource persons from the NAMRIA Hydrography Branch (HB): Sea Level Trends: A NAMRIA Perspective
, by the Physical Oceanography Division (POD) Chief Dennis Arsenio B. Bringas; and Future NAMRIA Project Proposals and Experiences in Relation to the Sea Level Observation in the Philippines
by POD’s Oceanographic Survey Section Chief, Engr. Jan Bryan O. Navarro.

A prayer on climate change kicked off the program, followed by the showing of the NAMRIA audio-visual presentation. An excerpt from Channel News Asia (CNA) Insider’s “Asia’s Sinking Cities” episode, where the City of Manila was featured, was also screened.
In his opening remarks, HB Officer in Charge (OIC) Dir., Capt. Antonio G. Valenzuela, Jr. explained that the rise and fall of sea levels may be attributed to several factors. He cited geothermal expansion of water due to global warming, tectonic activity, or vertical land motion. He said that “the rising sea level trend observed in a tide station may not be due to rising sea level but due to subsiding soil.” After the webinar’s presentation and discussion proper, the resource persons answered the questions of the participants through a question-and-answer portion. Geospatial Information System Management Branch (GISMB) Director Febrina E. Damaso concluded the program by thanking the resource persons, organizers, and participants for making the webinar a success. She also hoped that everyone gained additional knowledge on climate change in relation to the mandates of NAMRIA.
The webinar was conducted through the partnership of HB and GISMB. POD-HB Chief Bringas and Geospatial Information Services Division (GISD)-GISMB’s Mr. Jeffrey A. Quodala served as the activity leads. Mr. Jeffrey M. Aguillon and Mr. Erwin D. Famatiga served as technical staff.
