If such steps are not taken, the increase in temperature could potentially exceed the 1.5 degrees Celsius threshold.
During a discussion here on Wednesday, the BMKG's greenhouse gas coordinator, Albert C. Nahas, informed that the agency's records for the 1951–2021 period show a rising trend in temperatures in Indonesia with the rate of increase varying from one area to another.
He noted that the largest rate of increase was recorded in the areas of Kalimantan, Sulawesi, and southern Sumatra, as well as Jakarta and its surrounding areas, with some areas experiencing an average increase of 0.15 degrees per 10 years.
"With a simplification of 0.15 degrees per 10 years, by the middle of the 21st century, Indonesia will have exceeded the 1.5-degree limit, which is often used as the threshold for climate change mitigation and adaptation," he pointed out.
He explained that under the Representative Concentration Pathway (RCP) 4.5 climate scenario, there will be an increase in the average temperature despite mitigation and adaptation measures. However, it will not be as high as in the zero mitigation RCP 8.5 scenario, he added.
"We can see how important mitigation action is, and it must not stop because even though we take mitigation and adaptation measures, the increase still occurs," he said.
