GIS Analysis Reveals Climate Trends and Projections Insights for Naga City

The Coastal Cities at Risk Project conducted by the Ateneo de Manila, Manila Observatory, National Resilience Council and the Ateneo de Naga University included data and information on the trends of various environmental parameters including temperature. The image below shows baseline temperature of Naga City for the months of March, April, and May covering 1986-2005.


Analysis of the data reveals distinct temperature patterns, with minimum average air temperatures ranging from 26.869 to 26.941 degrees Celsius (°C), predominantly observed in the upper barangays or elevated areas, while maximum average air temperatures range from 27.159oC to 27.232°C, typically felt in the downtown or urban barangays. 

Building upon these findings, projections for the period from 2016 to 2035 anticipate significant increases in air temperatures. According to these projections, the minimum increase in average air temperature ranges from 1.1374 to 1.1408 °C, predominantly affecting downtown or urban areas resulting in a 28.297 to 28.386 °C temperature. Likewise, the maximum increase ranges from 1.1509 to 1.1543 °C, primarily impacting upper barangays and elevated areas resulting in a 28.006 to 28.089 °C temperature.

These projections align with findings from the Intergovernmental Panel on Climate Change (IPCC) Report for 2023, emphasizing the critical importance of present and near-term decisions in shaping the climate future for generations to come.

These maps were generated using GIS at the REGIS Hub of INECAR, Ateneo de Naga University. Do you want to effectively visualize data that can easily be analyzed like what we did here?
