Abstract: Dampak yang paling terasa dari perubahan iklim adalah peningkatan suhu. IPCC pada tahun 2018 menyatakan bahwa penyebab utama perubahan iklim adalah aktivitas manusia. Kegiatan industri 50 tahun terakhir menyebabkan suhu rata-rata global meningkat 0,76 oC pada tahun 2005. Perjanjian internasional seperti Paris Agreement dibuat guna membatasi kenaikan suhu rata-rata global dibawah 1,5 oC. Penelitian ini bertujuan untuk mengetahui wilayah yang rentan terhadap perubahan iklim di Sumatera Utara. Wilayah yang rentan dapat diketahui dengan mengombinasikan potensi peningkatan suhu wilayah dengan kepadatan penduduk di Sumatera Utara. Climate change hotspots digunakan untuk mengetahui wilayah yang berpotensi mengalami kenaikan suhu hingga 1 oC menggunakan data model CSIRO, MIROC, BCC dan CCSM4 pada skenario RCP 4.5. Hasil penelitian menunjukkan wilayah Sumatera Utara yang berpotensi mengalami peningkatan suhu sebesar 0,75 oC sebanyak 18 kabupaten pada model CSIRO dan 30 kabupaten pada model MIROC. Potensi peningkatan suhu 1 oC di Sumatera Utara sebanyak 20 kabupaten pada model MIROC. Hasil dari potensi peningkatan suhu dikombinasikan dengan kepadatan penduduk yang menghasilkan 5 kelas prioritas yang rentan terhadap perubahan iklim, dengan kelas prioritas 1 merupakan wilayah yang paling rentan terhadap perubahan iklim.
The most pronounced impact of climate change is the increase in temperature. The IPCC in 2018 stated that the main cause of climate change is human activity. Industrial activity in the last 50 years caused the global average temperature to increase by 0.76 oC in 2005. International agreements such as the Paris Agreement were created to limit the rise in global average temperatures below 1.5 oC. This study aims to determine the areas that are vulnerable to climate change in North Sumatra. Vulnerable areas can be known by combining the potential for increasing regional temperatures with population density in North Sumatra. Climate change hotspots are used to determine areas that have the potential to experience temperature increases of up to 1 oC using CSIRO, MIROC, BCC and CCSM4 model data in the RCP 4.5 scenario. The results showed that the North Sumatra region had the potential to experience an increase in temperature by 0.75 oC as many as 18 districts on the CSIRO model and 30 districts on the MIROC model. The potential for a temperature increase of 1 oC in North Sumatra is as many as 20 districts in the MIROC model. The result of the potential increase in temperature combined with population density results in 5 priority classes that are vulnerable to climate change, with priority class 1 being the region most vulnerable to climate change.
