Clean Water and Sanitation (SDG 6), Climate Action (SDG 13)
Investigation of climate variability in different regions of Papua New Guinea related to global warming and El-Nino La-Nina effects Malcolm Dopaim 1 and Felix Beslin Pereira 2* 1 Division of Physics, University of Goroka, Papua New Guinea. 2 Department of Applied Physics, University of Technology, Papua New Guinea. 1 Malcolm Dopaim: dopaimm@unigoroka.ac.pg 2 Felix Beslin Pereira: felix.pereira@pnguot.ac.pg Study of climate change is crucial as far as a nation’s agriculture and thus economy is considered. In this study, we analyzed the temporal and spatial variations of atmospheric temperature and rainfall in Papua New Guinea using published meteorological data from 2001 to 2020. A significant increase in trend of yearly averaged maximum temperature (T max ) with an increase of 0.020 C/year and minimum temperature (T min ) with an increase of 0.0150 C/year and an increase in trend of rainfall is observed in the country. In Kavieng, the temperature variation and rainfall are associated with El-Nino La-Nina effects. The average increase in temperature is found to be 0.20C for the period 2001-2020 which is same as the global average increase in temperature of the atmosphere. This rise in temperature is due to global warming. Key words: Climate Change, Temporal, Spatial, variation, Increase, Temperature
