Located in the northern midland and mountainous region, Bac Giang's economy depends on natural conditions, especially agriculture, forestry, and tourism. Thus, climate change has significantly impacted the province's socio-economy. This correlational study finds a correlation between time and temperature factors. However, the variation trend of the annual average maximum or minimum temperature is more common than that of the annual average temperature. The trend of changes in the temperature factors is highest in the western territories of the province and lowest in the high terrain in the eastern part of the province, in mountainous districts. The research results will be used for the next local climate change response plan to ensure the sustainable socio-economic development of the province.
