Climate Change Study via the Centennial Trend of Climate Factors
Background : The purpose of this work is to discover underlying trends of climate factors, identify their peaks and inflection points between 1880 and 2017, and study their response to climate change. Five climate factors including Land Temperature, Sea Surface Temperature, Temperature Over Land Plu...
