BALI - The Meteorology, Climatology and Geophysics Agency (BMKG) said that the sea level in Indonesia is estimated to increase by 0.8-1.2 centimeters (cm) per year due to the impact of climate change. "This is significant because it has an impact on the loss of several small islands in the territory of Indonesia or the coastal urban area," said BMKG Center Climatology Research and Development Coordinator, Donaldi Permana in a virtual seminar in Denpasar, Bali, Antara, Thursday, April 18. In his presentation, Donaldi also mentioned the national situation affected by climate change, namely an increase in temperatures of 0.45 to 0.75 degrees Celsius. In addition, it is estimated that 5.8 million square kilometers of Indonesian waters are dangerous for fishing boats, especially those less than 10 gross tonnage (GT). Then, as many as 18 thousand kilometers of coastline are estimated to fall into the vulnerable category due to climate change and changes in rainfall by about 75 millimeters per month. Meanwhile, the global average temperature has also increased over the last 10 years, namely 2014-2023 reaching 1.20 plus minus 0.12 degrees Celsius above the 1850-1000 period. He explained that the increase in temperature caused global warming, especially due to the high concentration of carbon dioxide due to the consumption of fossil energy, including coal, massive petroleum. In addition, deforestation is one of them for land clearing because it is associated with high demand after the growth of the world's population. The rising temperature also contributed to the disbursement of ice on the north and south poles which pushed sea level rise globally to reach around 4.72 millimeters per year in the period January 2013-December 2022. “ The affected early rise in sea level is a country in a tropical climate region compared to countries in the northern and southern hemispheres,” he said.

To suppress global warming, he revealed that mitigation efforts need to be made, including by reducing the use of fossil fuels, switching to using clean energy or new renewable energy. In addition, reforestation movements, saving electricity, and reducing the use of private vehicles.
